New Goodyear tires will be used for the NASCAR Cup and XFINITY Series races at Dover International Speedway this weekend (Sept. 30). All four tires will be a different compound from the last race at Dover in June as Goodyear reacts to NASCAR’s new low-downforce aero package.
NBC Sports reported that the tires were borne out of a Goodyear tire test at Dover on July 25 conducted by Dale Earnhardt Jr., Matt Kenseth, Joey Logano, Landon Cassill and Chris Buescher.
The left-side will change to enhance grip, while the right-side tire will be more durable to cope with the loads of Dover’s high degree banking. The right-side tire will also rubber-in the Dover concrete surface to a more adequate level.
Cup teams will receive four practice sets, one qualifying set and eight race sets, while XFINITY teams will get six sets for the whole weekend.
Left-side tires have a minimum recommended pressure of 19 psi and the rights at 45 psi.
In addition, a single-day Goodyear tire test was held on Tuesday at Bristol Motor Speedway. Participating for Furniture Row Racing were No. 77 driver Erik Jones and Ty Dillon in a Richard Childress Racing Chevrolet. This test was designed to test new tire compounds for next years’ races at the high-banked half-mile.
