NASCAR will use a smaller fuel cell and a different tire compound for the Nextel Cup and Busch races at Las Vegas Motor Speedway March 10-11. “We decided to go with a 13-gallon fuel tank for Las Vegas,” said Pemberton. “We discussed it with Goodyear and felt we have the potential for some of the same issues we had at the Charlotte track last year.” The fuel cell this season for most races is 17.5 gallons. Using a smaller fuel cell will cause the teams to pit at shorter intervals, enabling crew members to check tire wear and make changes frequently, if needed. NASCAR officials were concerned with tire wear last year at Lowe’s Motor Speedway after the surface was repaved, which added additional grip. The Las Vegas track was completely rebuilt in the offseason, adding increased banking to the new surface. Cup teams tested at the 1.5-mile two weeks ago and the Busch teams were there last week. Some drivers complained about the speeds the cars were reaching on the new asphalt, along with the hardness of the tires. “Goodyear has decided to change the left-side compound [at Las Vegas] and maybe a construction that is different from the tests,” Pemberton said. “As we go into the day and age with new pavement, the surface is a little too abrasive right off. We just need one race under our belts. We have to get a little time on the racetrack.”(ESPN.com)(2-11-2007)
