Goodyear held a tire test at Dover with the No. 8 Dale Earnhardt Incorporated Chevrolet (Mark Martin) and #43 Petty Enterprises Dodge (Bobby Labonte) on September 3 . . . based on that test, Goodyear decided to bring back a different right-side tire than it ran at the track earlier this season . . . “Our goal was to provide a slight increase in grip without negatively impacting tire temperatures or wear, and we feel like we accomplished just that,” according to Greg Stucker, Goodyear’s director of race tire sales . . . the new right-side code (D-4186) will be paired with the same left-side code (D-4134) that teams ran here before . . . teams in both the NASCAR Sprint Cup and Nationwide Series will run the same tire codes at Dover this weekend . . . in addition to Dover, this left-side code has been run with a different right-side code at Texas, Michigan (twice), Chicagoland and Kentucky (Nationwide only) already this season . . .unique among NASCAR’s one-mile ovals, teams are required to run inner liners in all four tire positions at Dover . . . air pressure in those inner lines should be 12-25 psi greater than that of the outer tire. The estimated pit window is every 75-80 laps, based on fuel mileage.(Goodyear PR), see pressures, codes and more on my Dover Race Info page or see codes for each race on my 2008 Tire Notes page.(9-20-2008)
