LMS Goodyear Notes

Teams in all three NASCAR series will run the same tire codes throughout Charlotte Speedweeks . . . this is the first time NASCAR teams will race on these tire codes at Charlotte . . . teams in both the Sprint Cup and Nationwide Series successfully tested on this tire set-up at Charlotte over the past several weeks . . . compared to the tire codes run at Charlotte in 2007, this left-side code (D-4128) has more grip, while this right side code (D-4130) contains incremental changes to enhance durability . . . Charlotte is the only track at which NASCAR teams are scheduled to run this specific combination of left- and right-side tires this season, though teams in the Sprint Cup and Nationwide Series raced on this right-side code with a different left-side at Darlington . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire. The estimated pit window for Sprint Cup cars is every 50-55 laps, based on fuel mileage. Goodyear PR
