Goodyear tire info for Bristol Motor Speedway

[ad_1]

NASCAR makes its first visit to Bristol Motor Speedway and “Thunder Valley” this weekend and it will do so with a new set of Goodyear tires in both Cup and Xfinity.

Compared to what was run at Bristol last year, this tire setup features construction updates on both sides of the car and a compound change on the left-side tire. This is the only track at which NASCAR teams are scheduled to run either of these two tire codes.

Unlike on most NASCAR ovals 1 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.

Here’s the tire info for this weekend’s races.

Set limits: Cup: Three sets for practice, one set for qualifying and nine sets for the race; Xfinity: six sets for the event

Tire Codes: Left-side – D-4860; Right-side – D-4862

Tire Circumference: Left-side — 2,223 mm (87.52 in.); Right-side – 2,251 mm (88.62 in.)

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