Storyline - At Bristol, Good Racing is as Simple as Black (Rubber) and White (Concrete): Goodyear brings a unique tire combination that matches up well with the concrete surface at Bristol. This tire set-up lays down rubber quickly, which helps create multiple racing grooves and makes for the highly competitive racing that Bristol is known for. While Bristol is a short track, it also has speedway characteristics. Goodyear's left- and right-side tire constructions are built with both in mind -- optimizing handling, as well as withstanding the loads and speeds generated by the steep banking.
Notes: Teams in both the Monster Energy NASCAR Cup and Xfinity Series will run the same Goodyear tire set-up at Bristol this week . . . this is the same combination of left- and right-side tires that NASCAR teams have run at Bristol since August 2014 . . . 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.
