Both Sprint Cup and Camping World Truck Series teams won’t have to worry about a new tire compound this weekend at Martinsville Speedway.
Goodyear will be providing teams with the same left and right-side tire combinations they have used at the short track since 2014. The left-side tire code has been used since 2013.
Left-side tires — D-4588; Tire Circumference: 87.44 in. (2,221 mm); Minimum Recommended Inflation: Left Front — 10 psi; Left Rear — 10 psi.
Right-side tires — D-4468; Tire Circumference: 88.70 in. (2,253 mm); Minimum Recommended Inflation: Right Front — 23 psi; Right Rear — 22 psi.
Martinsville is the only track where NASCAR teams are scheduled to run either of these two tire codes. Teams will not run inner liners in their tires at Martinsville.
Sprint Cup teams will have five sets of tires for practice and qualifying and 10 for the Sunday’s race. Truck series teams will have five sets of tires for the entire weekend.
