Both the Sprint Cup Series and Xfinity Series will use the same tires codes this weekend at Bristol Motor Speedway. It will be the only track both series are scheduled to use the tire, which has been used since last year’s April race at the half-mile bullring.

Left side -- D-4416; Tire Circumference: Left-side -- 87.64 in. (2,226 mm); Minimum Recommended Inflation: Left Front -- 20 psi; Left Rear -- 18 psi.

Right side -- D-4526 ; Tire Circumference: 88.43 in. (2,246 mm); Minimum Recommended Inflation: Right Front -- 41 psi; Right Rear -- 38 psi.

Teams are required to run liners in their right-side tires only at Bristol. Air pressure in the inner liners should be 12-25 psi greater than that of the left-side tire.

Sprint Cup Series teams will be given five sets of tires each for qualifying and nine sets for Sunday’s race. Xfinity Series teams will be given six sets for the entire weekend.
