Bristol NASCAR Goodyear Tire Notes
Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same Goodyear tire codes at Bristol this week -this is the same combination of left- and right-side tires these teams ran at this track last August.
Bristol is the only track at which NASCAR teams are scheduled to run either of these two tire codes – unlike on most NASCAR ovals one mile or less in length, on which teams generally do not run inner liners in their tires, teams are required to run liners in their right-side tires only at Bristol.
Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire. Goodyear Technical Bulletin.
