All three NASCAR national series are in action this weekend at Bristol Motor Speedway, and they will all use the same Goodyear tire setup.

Action begins Wednesday night with the Camping World Truck Series UNOH 200 and teams expect there to be a lot more grip on the bottom after Bristol recently “polished” the lower groove.

TRUCK, XFINITY, AND SPRINT CUP TIRE INFO: 

Set limits: Sprint Cup – five sets for practice and qualifying and nine sets for the race; Xfinity – six sets for the event; Camping World Truck – five sets for the event

Tire Codes: Left-side — D-4416; Right-side — D-4526

Tire Circumference: Left-side — 87.64 in. (2,226 mm); Right-side — 88.43 in. (2,246 mm)

Minimum Recommended Inflation: Left Front — 20 psi; Left Rear — 18 psi; Right Front — 43 psi; Right Rear — 40 psi

Teams in all three NASCAR national series will run the same Goodyear tire setup 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.
