  • Several teams have tire problems at Texas: When Sunday's race got under way on Sunday afternoon, it did not take long for tire issues to pop up. Chase driver #22-Joey Logano was running fourth in the opening laps of the race when his left-rear tire exploded, going down the backstretch. The shredded tire destroyed the left-rear quarter panel of the car, brought out the first caution of the day and took the Team Penske driver out of contention. On Lap 36, reigning series champion #4-Kevin Harvick also had a flat left-rear tire, but the car did not suffer any damage. With just 54 laps to go, Harvick had another flat tire -- this time it was the left rear. Harvick was forced to give up the second spot to hit pit road. Crew chief Rodney Childers determined Harvick ran over a piece of debris on both occasions.
    The tire problems were far from over, though. #88-Dale Earnhardt Jr. had a right-front tire go down on Lap 50. #42-Kyle Larson suffered two separate left-rear tire failures on Lap 101 and Lap 232. #31-Ryan Newman lost a left rear on Lap 145. Kyle Busch had a tire coming apart on his #18 Toyota, but was able to hit pit road during a cycle of green flag pit stops with 84 laps to go, and did not lose any ground.
    Despite the multiple problems, Goodyear's director of racing, Greg Stucker, said it was a myriad of issues causing the tire failures in Sunday's race, but he stood behind the compound. Stucker said both Harvick and Earnhardt ran over debris, which cut the tires. "The left rear is most certainly the most common occurrence," Stucker said inside the Texas Motor Speedway media center during the race. "We're seeing signs of over-deflection type air losses, which we have seen before. I think one of the other factors you have to consider is the impact the weather had." Stucker pointed out that with no practice on Saturday, teams were unable to properly gauge the tire wear and find the edge. "I think that's just where we are right now," he said. "They're still trying to sort through that and find where they can be with left-rear deflection, where they can be with air pressures and where they can be with their setup." The tire compound used Sunday at Texas is the same that will be run in the season finale at Homestead-Miami Speedway.(Fox Sports)(11-9-2015)

  • Drivers complete test at Atlanta: NASCAR Sprint Cup Series drivers were on track at Atlanta Motor Speedway participating in test sessions for the second straight week on Tuesday and Wednesday this week, ahead of the 2016 Folds of Honor QuikTrip 500 Weekend. #1-Jamie McMurray, #17-Ricky Stenhouse Jr., Bobby Labonte and David Ragan, again subbing in for Carl Edwards in the #19 car, were all on hand for a closed Goodyear tire test. The Goodyear test followed a Sprint Cup Series open team test last Thursday in which teams were testing the low-downforce aero package that will be used full time next season and for the first time at Atlanta. Inclement weather shortened the sessions on both days, but cars were eventually able to log laps after jet dryers worked overtime to prepare the track for safe driving. Tuesday, drivers worked predominantly on short runs, while longer runs were the name of the game on Wednesday. Often, Goodyear will invite a handful of teams to participate in a tire test as they prepare a new tire customized for optimal performace at specific tracks. Atlanta Motor Speedway's aged, rough surface popular with many drivers, combined with the new aero package in 2016 prompted the track to host the test in preparation for the unique racing anticipated in next season's Sprint Cup Series event.(AMS)(11-7-2015)

  • Some teams using shorter valve stems: Some Sprint Cup Series teams began using shorter valve stems in their tires two weeks ago at Charlotte Motor Speedway, a move that they hope will lessen the likelihood of suffering a flat tire caused by contact with lug nuts. There have been several instances of flat tires shortly after pit stops this year, and at least one crew chief has said lug nuts hitting the valve stems during tire changes have been the culprit. The shorter stems, it is believed, are less likely to be struck in the rush of a pit stop. "It's not a new design; we just shortened it as much as we can to allow the same core to be inside the valve stem," Greg Stucker, Director of Race Tire Sales for Goodyear, said. "It just gets it out of the way a little bit more. It's not going to be a fix; but that's all we can do right now. It's a reaction to the people wanting us to do something so we did it as quickly as we could."(

  • Goodyear expects to use softer tires in 2016: Goodyear is expecting to build more softer tires with the adoption of a lower downforce rules package for the 2016 Sprint Cup season. Greg Stucker, the director of race tire sales for the NASCAR supplier, said tires will be tuned to each track with a goal of increasing grip. That likely will mean a softer compound at many 1.5-mile to 2-mile tracks, but tires are expected to remain the same at Daytona International Speedway and Talladega Superspeedway (neither of which will feature the new package) and short tracks such as Martinsville Speedway and Bristol Motor Speedway. "There will be some commonality but probably a lot of change through the rest of '16," Stucker said Friday morning at Kansas Speedway. Even as the tire construction changes, Goodyear probably will continue to use the same combinations at multiple tracks. For example, the 1.5-mile ovals of Chicagoland Speedway, Texas Motor Speedway and Homestead-Miami Speedway traditionally have featured the same tire compounds. NASCAR has stressed it plans to tinker with gear ratios on a weekly basis to improve the quality of racing, but Stucker said that won't have an impact on tire production.(NBC Sports)(10-17-2015)

  • NASCAR to meet with teams at New Hampshire about 2016 rules package: NASCAR will hold a meeting with drivers, crew chiefs, manufacturers and Goodyear next Friday in New Hampshire to help chart the course for the 2016 Sprint Cup rules package. "I think (the rules will) be finalized," Goodyear general manager of worldwide racing Stu Grant told NASCAR Talk in a Saturday interview at Chicagoland Speedway. "It should be a good session to say here's where we are going to make sure we're on the same page." After receiving rave reviews at Kentucky Speedway and Darlington Raceway, it's expected the low-downforce package assuredly will be implemented next season at 1.5-mile superspeedways (which comprise the bulk of the schedule with 13 of 36 races). Grant expects much of Friday's discussion to focus on whether the low-downforce package also would be used at short tracks (Richmond International Raceway, Martinsville Speedway, Bristol Motor Speedway) and the bigger ovals (Michigan International Speedway and Indianapolis Motor Speedway). The low downforce package is intended to reduce the emphasis on aerodynamics, theoretically enhancing drivers' ability to pass because their cars aren't as glued to the asphalt. Aerodynamics typically play less of a role on short tracks, but there was chatter last Saturday after a mostly lackluster regular season finale at Richmond International Raceway that low downforce would work on the 0.75-mile oval.
    Grant said Goodyear is a "big fan" of using low downforce more frequently. "It brings tires into play and takes aero away," he said. "We were really happy with the results we had (at Kansas). We're big fans of taking the air away. The stress on the tire and loads run for years has been tough at these fast tracks. Take some of the load off the tire, and it gives us more freedom to design. I like that." Goodyear will begin production on its NASCAR tires by the end of October for next season's Daytona 500 (though that race wouldn't feature low downforce). It has scheduled further 2016 testing within the next month at Phoenix International Raceway and Atlanta Motor Speedway and also will test at Homestead-Miami Speedway in December and Las Vegas Motor Speedway in January.(NBC Sports)(9-20-2015)

  • Test at Auto Club cancelled: NASCAR has cancelled a Goodyear tire test and open team test scheduled for Oct. 27-29 at Auto Club Speedway in Fontana, CA. Goodyear determined it wasn't necessary to return to the 2-mile track based on tire wear results from this past season's race. And with Goodyear canceling the two-day portion of the test, teams opted not to make the cross-country trek a day before having to be in Martinsville, Virginia, for the opening race of the Eliminator Round in this year's Chase. Only two open tests remain on this year's National Series Unified Testing schedule -- next week (Sept. 14-16) at Kansas Speedway and Oct. 12-14 at Phoenix International Raceway.(

  • Teams to test at Homestead UPDATE: NASCAR has scheduled a Sprint Cup Series test for Homestead-Miami Speedway on Wednesday, August 26. One team from each organization will be eligible to take part in the test, which will run from 9:00am-5:00pm. Teams will test at Homestead-Miami Speedway in preparation for the season-ending Ford EcoBoost 400 on Sunday, November 22, where the Championship 4 drivers will battle for the 2015 NASCAR Sprint Cup Series championship. Testing will be open to the public from 9:00am-5:00pm in the infield Pit Road Cabanas, as well as from the chair-back seats in the Speedway Club on the fourth floor of the tower building. Fans may enter and park in the parking lot on SW 336thStreet and SW 137th Avenue and take a tram into the infield to watch testing. Snacks and drinks will be available for purchase in the infield.(Homestead-Miami Speedway)(8-18-2016)
    UPDATE: Four drivers will participate in a Goodyear tire test at the 1.5-mile South Florida track Monday and Tuesday with an open test scheduled for Wednesday -- NASCAR allowing each Sprint Cup Series team to be represented by one car. Trevor Bayne (Roush Fenway Racing), Clint Bowyer ( Michael Waltrip Racing), Ryan Newman (Richard Childress Racing) and Kyle Larson (Chip Ganassi Racing with Felix Sabates) are scheduled for the Goodyear test.

  • Goodyear explains early unusual tire wear at Sonoma: Tire issues affecting at least four NASCAR Sprint Cup Series teams during Sunday's Toyota/SaveMart 350 were the result of the soft compound and harsh race conditions, according to Goodyear. The teams of #1-McMurray, #78-Truex Jr., #24-Gordon and #48-Johnson saw unusual tire wear after early pit stops in the 110-lap race. According to a Goodyear spokesperson, the tire being used for Sunday's race was on the softest end of the range of compounds. Compared to what was used previously at Sonoma, this tire featured increased thickness for improved wear, however some tires were showing signs of tearing. Individual set-ups by the teams were not considered factors in the unusual wear.(

  • Goodyear schedules June 30 test at Darlington: A tire test with three Sprint Cup teams has been scheduled for June 30 at Darlington Raceway, Goodyear confirmed Tuesday. The session will include Brad Keselowski's #2-Ford, Tony Stewart's #14-Chevrolet and Matt Kenseth's #20-Toyota. This will be the second Goodyear test at Darlington in three weeks. NASCAR held a two-day test at the 1.366-mile oval on June 9-10 with the first day devoted to testing tires for the Southern 500 on Sept. 5. It's common for Goodyear to hold "confirmation" tests in the weeks leading into a race to select a tire, but it's unusual for multiple sessions to be conducted. The test is unrelated to the July 11 race at Kentucky Speedway, which will feature the debut of a lower-downforce rules package that NASCAR is trying in the hopes of increasing lead changes. NASCAR hasn't committed to the change beyond Kentucky, but executive vice president and chief racing development officer Steve O'Donnell hinted Monday that another race-specific rules package could be rolled out prior to the Chase for the Sprint Cup.(NBC Sports)(6-24-2015)

  • Testing at Richmond: A week after testing at Darlington Raceway, it's off to Richmond International Raceway for Goodyear officials and a handful of NASCAR Sprint Cup Series teams. The official tire supplier for NASCAR will test with four teams Tuesday at the 0.75-mile track in preparation for this year's Chase for the NASCAR Sprint Cup cutoff race. #42-Kyle Larson (Chip Ganassi Racing with Felix Sabates), #6-Trevor Bayne (Roush Fenway Racing) and #55-David Ragan (Michael Waltrip Racing) are scheduled to take part in the Goodyear tire test. NASCAR XFINITY Series driver Brian Scott (Richard Childress Racing) will also take part, stepping into the #27 for driver Paul Menard. The four will join several others on Wednesday for an open team test. According to officials, those scheduled to be on hand are #24-Jeff Gordon (Hendrick Motorsports), #19Carl Edwards (Joe Gibbs Racing), #22-Joey Logano (Team Penske), #9-Sam Hornish Jr. (Richard Petty Motorsports), #30-Jeff Green (The Motorsports Group) and #75-Clay Rogers (Beard Motorsports). Stu Grant, Goodyear's general manager for global race tires, said several options would be considered. "We've got a pretty good baseline at Richmond," he said. "I don't want to move too far off of that. We're not going to test a whole lot of different things. We ran a (multi-) zone tread at Richmond; we'll try a couple of zone treads, we'll try a couple of non-zone treads to see what happens ... we don't have a real big program (scheduled) so we can get that done in a day." Wednesday's test will be open to fans, with access to the grandstands through Gate 70 only.(

  • Goodyear still working on tires packages: The discussion continues between NASCAR and Goodyear as to what type of tire compound best suits the Generation 6 Sprint Cup car. While the tires were first in the news last weekend for the "Support Our Troops" branding as part of the Goodyear Gives Back program, the focus changed to the tire itself following the Coca-Cola 600. Although many of the teams have acclimated to the right-side multi-zone tires at Charlotte Motor Speedway by reducing camber to increase the contact zone and achieve grip, others are still searching for the right feel. Listening to Sunday's radio chatter and the consequent conversation on Twitter, it was clear that the current combination was a struggle for many of the competitors. Goodyear provided teams with the same left-side tires at the 1.5-mile track since 2012, the right-side tires were first run at Charlotte in the All-Star Race - as well as in the XFINITY Series race last Saturday. Teams first tested the tire in December with the new rules package for the Gen 6 cars. A confirmation test followed on March 10 performed by Martin Truex Jr., Aric Almirola, Kasey Kahne and J.J. Yeley. Introduced in 2013, the multi-zone tread tire incorporates two different compounds - one as a safety measure, the other for traction. The inside two inches is a more durable compound designed to resist heat. The "endurance zone" compound was used at Texas earlier this season. The outside 10 inches of tire features a tread intended to provide more grip for the drivers, hence the "traction zone". Still, as NASCAR attempts to solve its aero issues with the 2015 car package - and develop another set of rules for 2016 - the onus has been put on Goodyear to provide a tire that will enhance the competition.
    "We have had a lot of discussions with NASCAR over the last couple of weeks and have covered everything from hard tires to super soft tires," Stu Grant, Goodyear's general manager of global race tires told "There is no clear direction at the moment. I would say it is a work in progress to figure out what the future rule package would be. Everything has been mentioned at one point over the last two weeks. We're fine as long as it's in the discussion stages but when it comes down to determining a strategy and a direction for a rules package and you start manufacturing tires and generating data, that's the long-leadb time item. You can talk all you want to about soft, hard, whatever tire but what we need to do is get some consensus on where we want to go and then say, alright Goodyear, this is where we want to go. But we need to get it finalized."(Motorsport)(5-28-2015)

  • Goodyear Gives Back" program - Support Our Troops: For the sixth straight year, The Goodyear Tire & Rubber Company, exclusive tire supplier of NASCAR's three major national series, is rallying NASCAR fans to support members of the U.S. Armed Forces through its "Goodyear Gives Back" charitable program benefitting the Support Our Troops organization. To kick off the program, Goodyear will once again transform its NASCAR race tires by replacing the "Eagle" sidewall design with "Support Our Troops" messaging on all tires used during Memorial Day weekend at Charlotte Motor Speedway. This effort coincides with the launch of Goodyear's charity auction at, which features autographed NASCAR memorabilia, VIP race experiences and rides on the Goodyear Blimp. Proceeds benefit Support Our Troops, a nonprofit nationwide organization that works to bolster the morale and well-being of America's troops and their families. To-date, Goodyear Gives Back has generated nearly $1 million in cash and product donations to support the cause.
    "For the past six years, the Goodyear Gives Back program has helped us bring race fans and the NASCAR community together in showing support for troops and their families," said Kris Kienzl, Goodyear's NASCAR marketing manager. "The response has been overwhelming. More than 40 NASCAR teams, sponsors and tracks have joined this year's effort by providing items for our charity auction and spreading the word among fans."
    Fans can get involved by visiting through July 6, 2015 to bid on unique NASCAR autographed items, Support Our Troops tires and VIP experiences, purchase Support Our Troops merchandise, or make a direct donation.
    "The Goodyear Gives Back program has played a critical role in raising awareness and funds to better the lives of service men and women and their families," said Martin C. Boire, executive director of Support Our Troops. "It's a great symbol of support for those who sacrifice so much for our freedom."
    This year's program is also a cornerstone of the "NASCAR: An American Salute" initiative, which highlights the sport's ongoing support of the U.S. Armed Forces and veterans. "The Goodyear Gives Back program continues to be one of the most visible symbols of military support during the Memorial Day race weekend," said NASCAR President Mike Helton. "We hope the combined efforts of Goodyear and NASCAR will encourage fans to show their support for the men and women who serve or have served our nation."(Goodyear)(5-24-2015)

  • Goodyear shortens upcoming Darlington test: Goodyear officials have changed next month's tire test at Darlington Raceway from a two-day to a single-day tire test, a move that will also change the date of the open team test. The Goodyear portion of the test, originally slated for Tuesday and Wednesday, June 9-10, has been shortened to a single-day test on June 9. The open team test will now be held Wednesday, June 10. Each NASCAR Sprint Cup Series organization may have one team on hand to participate in the open test. Organizations scheduled to participate in the Goodyear portion of the test are Richard Childress Racing, Roush Fenway Racing, Michael Waltrip Racing and Chip Ganassi Racing with Felix Sabates. Only one Goodyear tire test and open team test is scheduled for this month, May 11-13 at Dover International Speedway. Organizations participating in the Goodyear portion, set for May 11-12, are Stewart-Haas Racing, JTG Daugherty Racing, Team Penske and Joe Gibbs Racing.(

  • Spring Goodyear testing underway: With the warming temperatures around the country, the Goodyear Tire & Rubber Company embarks on one of its rites of spring - testing season. The busy schedule started with a test two weeks ago -- April 7 -- at Richmond International Raceway with drivers A.J. Allmendinger, Denny Hamlin, Brad Keselowski and Tony Stewart. Coming out of that session, Goodyear confirmed a set-up that included the same left-side tire as last fall with a new multi-zone-tread right-side tire. NASCAR's official tire supplier followed that up this week - April 13-14 - with a test at Kentucky Speedway. Drivers participating in that test were Greg Biffle, Jamie McMurray, Brett Moffitt and Ryan Newman.
    "The main objective of the Kentucky test was to bring the right-side tire there in line with several of the other high-speed mile-and-a-half speedways. What we tested incorporated a different mold shape and construction from what we raced there in the past," said Greg Stucker, Goodyear's director of racing. "Additionally, with the lower downforce of the 2015 rules package, we felt a left-side compound adjustment to increase grip was justified. Both those goals were met, and all drivers involved in the test felt like the new combination was a nice improvement over the package raced in 2014 and prior."
    Next up on the calendar is a trip to the famed Indianapolis Motor Speedway on April 27-28. The organizations scheduled to take part are BK Racing, Furniture Row Racing, Hendrick Motorsports and Richard Petty Motorsports.
    "The ground track surface at Indy makes it very sensitive to tire set-up," said Stucker. "The focus of the Indy test will be to make sure we have the correct tire combination to match the new characteristics of the low downforce, low horsepower 2015 rules package. The surface of the track is very abrasive, so getting the correct compounds and constructions to generate the desired wear characteristics, while maintaining the level of grip for competitive racing, is critical."
    This season has brought a host of changes to the Sprint Cup set-up, and Goodyear has reacted to that with changes to race recommendations for three of the first eight points races. "To date, we're happy with the way the 2015 season has gone," said Stucker. "We feel like those adjustments we have made to tire recommendations from 2014 have been nice improvements, adding back some of the grip in a mechanical fashion to compensate for some of the grip lost through the aerodynamic downforce reduction. That will continue to be our focus in 2015 testing."
    Upcoming Goodyear test sessions include Iowa Speedway on May 5 (Xfinity Series only), Dover International Speedway on May 11-12 and Darlington Raceway on June 9-10.(Goodyear Racing)(4-18-2015)

  • Goodyear explains problems of altering tires: The biggest topic of conversation over the past few weeks in the NASCAR garage has been tires -- more specifically, teams altering tires. Starting at the end of the 2014 season, NASCAR began taking tires from select teams as their post-race inspection process. The practice began again this year starting with the third race of the Sprint Cup Series season at Phoenix International Raceway. The rumor in the garage has been team are poking tiny 0.001- to 0.002-inch holes in the sidewall of the tire to bleed air pressure, allowing the tire to reach optimal pressure sooner and maximizing grip. Last week, NASCAR issued a P5 penalty to the #31 Richard Childress Racing team for manipulating tires at Auto Club Speedway. NASCAR did not say specifically how the tires were altered, and the team has appealed the penalty. While it is clear altering tires is a major violation of the NASCAR rulebook, why is it a bad idea to do so? Greg Stucker, director of racing for Goodyear, sat down with Friday at Texas Motor Speedway to explain.
    "The tire is a structure and it's kind of a membrane, it requires the air pressure to give it rigidity and to give it the load-carrying capacity that we need," he said. "It's not just the tire itself; it's a combination of the tire and the inflation pressure that's in the tire, the air that you put in the tire that enables it to carry that load. We make a pressure recommendations knowing what the loads are at a place like Texas, knowing what the construction of the tire is, so those two work together to carry the loads that the car is going to see," said Stucker. "If you try to manipulate that you could be operating outside the envelope where the tire is meant to operate. The other thing is ... you run the risk of damaging the structural members of the tire itself," he said. "The tire has cords; it has fabric that creates its structure. If you damage one of those cords, then you lower the integrity of that component. You certainly have a high risk that the tire could fail because you've damaged one of the components."
    So while NASCAR made it clear with the penalties to Newman and the No. 31 RCR team that altering tires isa major offense, there is much more to the reasons behind the rule. According to Stucker, altering tires is not a concern for Goodyear in terms of competitive advantage; it is really all about maintaining the integrity of the tires on each car on the track.(FoxSports)(4-12-2015)

  • NASCAR opposed to use of bleeder valves: In other forms of motorsport, including short track and dirt racing, bleeder valves [for tires] are commonplace and allowed. That has been the number one question in the aftermath of the tire tampering penalty handed down to Ryan Newman, Richard Childress Racing and the #31 Sprint Cup Series team last week. This had prompted numerous drivers to suggest that NASCAR would be better off allowing bleeder valves as well. Jeff Gordon has been perhaps the most vocal proponent of bleeder valves in the Sprint Cup garage. Sprint Cup Series director Richard Buck [says] the technology is too inconsistent for use in NASCAR.
    "In regard to the tire bleeders, we work our partner Goodyear and with our teams and at this point, I personally don't know if there are any bleeders out there at the level that these cars would require," Buck told Popular Speed on Friday afternoon. "I know there are other forms of motorsports like dirt car racing and sprint car racing that I've seen before and (those valves) were very touchy and non-repeatable. If they fail, it was a catastrophic failure of the system, so I don't think there is a system that is out there today." Furthermore, Buck is content without having bleeder valves because it's the same and fair for everyone in the garage. "It allows teams to adjust on the tires," Buck continued. "It allows for drivers to provide feedback on the tires. A driver can change the handling based on how he changes the load of the tire pressure. "So there still a lot of human interaction in working with the tires."(Popular Speed)(4-11-2015)

  • Testing at Kentucky: Eight NASCAR Sprint Cup drivers and teams are scheduled to participate in the April 15 open test at Kentucky Speedway ahead of the track's Quaker State 400 in July. The open test will be preceded by a closed Goodyear tire test on April 13 and 14 with one team each from the following organizations: Chip Ganassi Racing, Michael Waltrip Racing, Richard Childress Racing and Roush Fenway Racing. On April 15, #16-Greg Biffle, #88-Dale Earnhardt Jr., #20-Matt Kenseth, #22-Joey Logano, #1-Jamie McMurray, #10-Danica Patrick, #31-Ryan Newman and #9-Sam Hornish Jr. are scheduled to participate in the open test with April 16 serving as a rain date before the Sprint Cup Series heads to Bristol Motor Speedway next weekend.(

Fans can enter the grandstands through Gate 70 only.(RIR) Teams will also test on Tuesday, but the track is close to the public then.(4-7-2014)
    UPDATE: The engineers and mechanics who hunched over an array of computers plied their trade with typical high-tech flair during Wednesday's open NASCAR test at Richmond International Raceway, analyzing data feeds and crunching numbers while their drivers made the rounds. The seven-hour session, which started 2 1/2 hours late because of early morning rain, came on the heels of Tuesday's rain-delayed Goodyear tire test here, where teams confirmed the rubber that will be used in the springtime 400-lapper. But in addition to making tires work, teams used the extra time to try different setups that may pay dividends in a little over two weeks. Thirteen drivers added the Richmond detour before heading to this weekend's racing at Texas Motor Speedway, driving cars equipped with ride-height sensors and pitot tubes to measure wind velocity. Additionally, three "wheel-force" cars -- one for each manufacturer and marked with a "W" beside their number on the scoring sheet -- also made the trip, each outfitted with a complex sensor attached to each wheel to measure load on the tires. The information from those three cars -- with Team Penske representing Ford, JTG-Daugherty Racing for Chevrolet, and Joe Gibbs Racing for Toyota -- would be shared within each manufacturer network. Tuesday at Richmond, teams tested tires for nearly four hours after steady showers pushed back the on-track schedule. Goodyear will employ zone-tread technology -- using two different rubber compounds, one for improved endurance and one for enhanced traction, in a single tread -- on its right-side tires. The left-side tire compound will remain the same as the one teams raced on last September.(

  • Are some teams tampering with tires? UPDATE: Hendrick crew chiefs Alan Gustafson and Chad Knaus talked to the media Friday morning at Martinsville Speedway:
    The last two weeks NASCAR has taken tires from teams. After Fontana they sent some of those tires off to an independent laboratory. NASCAR said that is a part of a regular tire audit. What do you guys make of what is going on there? Do you thing they are looking for something specific?
    GUSTAFSON: "It's hard to speculate because that is all I could do. In my experience there is a lot of smoke around that. There is a lot of talk, there is a lot of dialogue and there are a lot of rumors in the garage. Yeah, I think it is obvious that some people think something is going on and is NASCAR reacting to that? Or do they feel uncomfortable with what is going on? I don't know that answer. But I do think that it is something that is on the forefront of a lot of people minds. Obviously NASCAR is trying to make sure that we are all on level playing field and if anybody is violating that they will pay the price, which they reminded us this morning is very stiff. That is all I know. Anything beyond that is speculation besides the fact it is a hot topic."
    So they warned you?
    GUSTAFSON: "I don't want to say warned. Warned may not be the right term, just reminded."
    Do you think something is going on?
    GUSTAFSON: "Do I think something is going on? I mean I'm busy on Sunday's. I don't really watch what is going on. It's hard for me to say. I don't feel that I have enough information that would warrant a comment."
    KNAUS: "I don't know. I don't know if there is anything or not. I really don't. Like Alan said, I'm busy on Sunday and I don't have a lot of friends in the garage. So, I don't talk too much. I don't talk to anybody else either so it's okay. My friends are outside of racing. So, I don't know what is going on. I really don't. I know I sent Richard Buck (Managing Director of the NASCAR Sprint Cup Series) a text and said 'hey man could we poke holes in our tires is that okay?' He sent me a text back and said 'absolutely not'. So that is all I know."(Chevy Racing PR)(3-27-2015)
    UPDATE: Alan Gustafson, Jeff Gordon's crew chief, termed it a "reminder." But those who may have engaged in alleged unapproved "bleeding" of air pressure from their racing tires-the source of prevalent rumors in the garage-would be well-advised to interpret it as a stern warning. When NASCAR assembled Sprint Cup Series crew chiefs for a Friday morning meeting at Martinsville Speedway one of the topics covered was to "remind" teams of the three primary taboos of NASCAR racing:
    " Don't alter the engines in a manner outside the rule book.
    " Don't do anything to alter the fuel provided by Sunoco.
    " Don't make any unapproved alterations or treatments to the tires provided by Goodyear.
    Tires, in particular, have been the center of attention since NASCAR made what it termed a routine "audit" of tires two weeks ago at Phoenix International Raceway. The consensus in the garage is that certain teams have been drilling minute holes in the tires to bleed off air pressure as it builds throughout a tire run. By maintaining consistent air pressure, it's easier to maintain the balance of the car.(NASCAR Wire Service)(3-28-2015)

  • NASCAR sends Fontana-used tires for further evaluation: NASCAR confirmed Wednesday that it sent some of the tires used by teams at Auto Club Speedway for further evaluation in a third-party review. The tires of #4-Kevin Harvick, #41-Kurt Busch, #27-Paul Menard and #31-Ryan Newman were taken after Sunday's Auto Club 400 and brought to the R&D Center in Concord, N.C., as part of what NASCAR deems a "tire audit." NASCAR wouldn't confirm which tires were sent for more examination, nor where they were sent. Goodyear is uninvolved in the process. The decision to confiscate the tires for further scrutiny was made independent of the tire supplier and unrelated to durability. Goodyear occasionally keeps tires for further examination (such as with tire failures on the cars of Brad Keselowski and Dale Earnhardt Jr. last October at Kansas Speedway). It was the second consecutive Sprint Cup race that NASCAR conducted a tire audit. After the March 15 race at Phoenix International Raceway, NASCAR checked the tires used by Joey Logano and Kevin Harvick and found nothing out of the ordinary. NASCAR executive vice president and chief racing development officer Steve O'Donnell told SiriusXM Satellite Radio's NASCAR channel that the audits were "just something we like to do every once in a while."(NBC Sports)(3-26-2015)

  • NASCAR reducing number of tires for teams at some tracks: NASCAR issued a bulletin Tuesday containing various updates to the Rule Book. The changes include a reduction in how many sets of tires a team can have for Sprint Cup races at Martinsville, Dover, Pocono, Michigan, Sonoma, Kentucky, New Hampshire Indianapolis and Watkins Glen. NASCAR cut the number of sets by one at each track for those races. Teams will be allowed 10 sets of tires for Sunday's race at Martinsville. They'll have nine sets of race tires available at Dover, Michigan, Kentucky and Indianapolis. Teams will have eight sets of tires for both Pocono races with seven sets available at New Hampshire's July race and five race sets at Sonoma and Watkins Glen. With a set of tires costing about $1,900, having to buy one less set will save teams teams about $20,000. NASCAR also reduced how many sets of tires teams are allowed for practice and qualifying by one set at Talladega (now allowed three sets), Daytona (three), Sonoma (four), Watkins Glen (four) and the August Bristol event (four). This reduction will save teams about $10,000. NASCAR has not set the limits for tires for the races starting with Richmond in September through the end of the season. Those races could provide teams more savings.(NBC Sports)(3-25-2015)

  • NASCAR examines tires from Harvick, Logano: NASCAR confirmed it found nothing out of the ordinary with the tires used by Joey Logano and Kevin Harvick in Sunday's Sprint Cup race at Phoenix International Raceway. The tires were seized during Sunday's 500 in what was described as a "regularly scheduled audit" by NASCAR executive vice president chief racing development officer Steve O'Donnell. "We've done it in the past," O'Donnell told SiriusXM's "The Morning Drive" during a Monday interview. "It's something we check working with Goodyear, making sure the tires supplied are where we want them to be. It's just another area of the car. We don't expect to find anything; it's just something we like to do every once in a while." NASCAR normally examines tires at its R&D Center in Concord, N.C., but those from Logano and Harvick were checked at a remote site with NASCAR haulers on the road in the midst of a three-race swing through Las Vegas Motor Speedway, Phoenix and Auto Club Speedway. The decision to confiscate the tires for examination was made independent of Goodyear and unrelated to durability. The tire supplier occasionally keeps tires for further examination (such as with tire failures on the cars of Brad Keselowski and Dale Earnhardt Jr. last October at Kansas Speedway).(NBC Sports)(3-17-2015)

  • Teams testing this week at Charlotte: Four teams are scheduled to take part in a Goodyear tire test test Tuesday at Charlotte Motor Speedway. Those teams are Hendrick Motorsports (#5-Kasey Kahne), Furniture Row Racing (#78-Martin Truex Jr.), Richard Petty Motorsports (#43-Aric Almirola) and BK Racing (#23-JJ Yeley). Tuesday's session is closed to the public. There will be an open test Wednesday at the track. Charlotte Motor Speedway officials state that teams expected to test that day include Kahne, Truex, Kevin Harvick, Joey Logano, Jamie McMurray and about half a dozen other teams. Wednesday's session is open to the public. Gates open at 9:00am. Testing is scheduled to run from 9:00am-12:00pm and from 1:00-5:00pm/et. The next scheduled test is April 7-8 at Richmond International Raceway. Four teams will test there. Each will have one car. Those teams testing will be Stewart-Haas Racing, JTG Daugherty, Team Penske and Joe Gibbs Racing. That begins a busy test period. Tire tests are scheduled April 13-15 at Kentucky Speedway and April 27-29 at Indianapolis Motor Speedway.(NBC Sports)(3-10-2015)

  • NASCAR no longer regulating minimum air pressure requirements: NASCAR will not regulate minimum air pressure requirements this season, giving crew chiefs more control of how little they put in their tires but also increasing the risk of a blowout. Goodyear will continue to provide teams with a minimum tire pressure recommendation. Previously, NASCAR mandated the right front tire pressure and, in some cases, left-front tires. Now, it is up to teams to determine how low they inflate their tires. Robin Pemberton, senior vice president of competition, said NASCAR is allowing teams to police themselves in this area. "With Goodyear constantly working on their communications with the teams on tire durability, it's putting it in the team's hands for different strategies,'' he told NASCAR Talk Friday at Daytona International Speedway. "How low they think they can go.'' Greg Stucker, Goodyear's director of race tires sale, said: "(Teams) have to make those calls. We try to give them as much data as we can for them to make those types of decisions.'' Pemberton said officials are working on having a tire pressure monitoring system on the dashboard to give drivers a warning when tire pressure is too low. Pemberton said that the system is "a ways away" from happening.(NBC Sports)(2-14-2014)

  • Atlanta tire test canceled: The March 2-3 NASCAR tire test at Atlanta has been canceled. That was to have been held Monday and Tuesday after the Atlanta race and just before the Cup series begins its three-week West Coast swing. Teams that were to have taken part in that test: Richard Childress Racing, Chip Ganassi Racing, Roush Fenway Racing and Michael Waltrip Racing.(NBC Sports)(2-3-2015)

  • Goodyear tire test at Las Vegas UPDATE: The first NASCAR test of the 2015 season is scheduled to take place Monday when four Sprint Cup Series teams participate in a one-day Goodyear tire test at Las Vegas Motor Speedway. The teams of #41-Kurt Busch (Stewart-Haas Racing) and #47-AJ Allmendinger (JTG Daugherty Racing) will be on hand as representatives for Chevy; #20-Matt Kenseth (Joe Gibbs Racing) is the Toyota entry while Brad Keselowski (Team Penske) and his #2 Ford team will be on hand to round out the test teams and vehicles. According to a Team Penske representative, Keselowski's teammate Joey Logano, crew chief Todd Gordon and several members of the #22 Team Penske group will be on hand as well to help and observe. In previous years, tire tests haven't generated a great deal of interest. Now that NASCAR no longer allows private team testing, however, track time is considered more valuable. Goodyear has scheduled 14 tests for the upcoming season; Monday's trip to Las Vegas is the only one currently on the schedule that does not dovetail with a team test. Others will be either one- or two-day tires tests followed by a single-day team test. For now, only a stop next month at Atlanta will see teams test prior to a Goodyear tire test at the facility. Teams will be given a four-hour window for testing one day before the start of that track's race weekend. A two-day Goodyear tire test will be conducted at the track on March 2-3 after the completion of the Sprint Cup event. In all other cases, the team test will come after the Goodyear test is completed.(
    UPDATE: Monday's Goodyear tire test at Las Vegas Motor Speedway took on added importance for drivers #20-Matt Kenseth and #2-Brad Keselowski because of a slew of rules changes put in place this year by NASCAR. Kenseth and Keselowski were joined by fellow Sprint Cup Series drivers #41-Kurt Busch and #47-AJ Allmendinger for the one-day test on the 1.5-mile LVMS speedway. Although all Cup drivers will have to adjust to a number of changes this season, including a reduction in horsepower and a modified aero package, the biggest change will be NASCAR's ban on all private testing in 2015.
    "I think any track time you get is really important with the new testing rules, banning all off-season testing, which I think we all like, but you've really got to take advantage of the tests when you get them and try to gather as much information as you can - hopefully useful information that you can use down the road," Kenseth said. "For us, we didn't run particularly well last year and we've got a new nose on the Camry this year and new rules changes and aero package and all that stuff, so we're just trying to get it sorted out and try to find a baseline and hopefully find something that drives good so we've got something decent when we come back here (March 6-8).
    Keselowski, the defending winner of both the Kobalt 400 Sprint Cup Series race and the Xfinity Series Boyd Gaming 300 at Las Vegas Motor Speedway, said he agreed with Kenseth. "More so than the changes to the car, the testing ban makes every test you do have that much more critical because you have so much less," Keselowski said. "In that light, a lot of what testing is isn't always developing the car, but you're developing your people, developing your techniques. We added two or three more people to our team so we're trying to develop them and get them up to speed, so it's really a great time for us as a team to have a test."(Las Vegas Motor Speedway)(1-20-2015)

  • Proposed 2015 NASCAR testing dates for Sprint Cup Series UPDATE: When NASCAR announced in September it was banning all private team testing, the perception was teams would not likely see the opportunity to do much on-track testing. NASCAR at the time said it hoped to incorporate more teams into the 12 to 15 tire tests done each season by Goodyear but that plan seemed to hit logistical roadblocks in recent months. The finished product, outlined in the 2015 NASCAR Sprint Cup Series Rulebook, actually provides teams many opportunities to test on series tracks in the coming season. At Atlanta, an extra testing day has been added to the regular weekend schedule. In addition, an extra day of open testing as been added to Goodyear tire tests at Charlotte; Richmond; Kentucky; Indianapolis; Dover; Darlington; Chicago Bristol; Homestead; Kansas; Phoenix; and Auto Club Speedway:
    Proposed 2015 NASCAR testing dates for Sprint Cup Series

    UPDATE: While teams will be prohibited from testing independently, there will be 12 Goodyear tire tests (with four teams apiece) that will be followed by a one-day open test that will allow one car per organization. Attendance isn't mandatory, and teams must indicate their attendance at least three weeks ahead. If a multicar organization has participated in the preceding tire test, it must use the same driver and team in the open test. The Goodyear tests will be held with a rotating set of three groups of four full-time teams. The first group comprises Stewart-Haas Racing, JTG Daugherty Racing, Joe Gibbs Racing and Team Penske. The second group: Richard Childress Racing, Chip Ganassi Racing, Roush Fenway Racing and Michael Waltrip Racing. The third group: Hendrick Motorsports, Furniture Row Racing, Richard Petty Motorsports and BK Racing.
    NASCAR also will hold "Rule Change Open Tests" in which all teams are allowed to "familiarize themselves with any rule changes from previous race seasons." The sessions will be limited to one "per racetrack grouping" (i.e. short tracks, road courses, speedways). A four-hour session Feb. 26 at Atlanta Motor Speedway (a 1.5-mile superspeedway) is the only Rule Change Open Test scheduled so far for the 2015 season.
    While any other tests are banned for existing teams, the 2015 rulebook allows "New Organization Testing" for those "new to NASCAR to establish themselves." Those teams will be allowed five two-day tests at any track and must be approved by NASCAR. The rulebook defines a "New Organization" as a team that hasn't competed in more than 20 races or two seasons, whichever is first. Teams absent from a circuit for five years also can qualify for new organization status. The Goodyear tests are closed to the public and the news media. The news media will be allowed at open tests, and the public will be permitted access at each track's discretion.(USA Today)(12-12-2014)
