Bristol Goodyear Tire Notes

Teams in both the NASCAR Sprint Cup and Nationwide Series will be running the same combination of left- and right-side tires at Bristol this weekend . . . this will be the first time Goodyear has brought this combination to the track in 2009, though this is the same tire set-up that NASCAR teams ran at both Bristol (both series) and Pocono (Sprint Cup only) in 2008 . . . Bristol is unique in that teams will be required to run inner liners in only their right-side tires this weekend . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire. The estimated pit window is every 130-140 laps, based on fuel mileage (Sprint Cup). Goodyear PR
