Storyline – Designing tire wear into Last Vegas tire set-up: Las Vegas has always been a low tire wear track. When race tires don’t wear, heat is allowed to build up and the they don’t run at an optimal level. To help introduce some wear on the Las Vegas surface, Goodyear designs the tread compound for this track to wear more on their own to help dissipate some of that heat. Being an intermediate track, teams are in a constant search for grip. One way they do that is reducing the air pressure in their tires. Goodyear has brought an updated construction to the Las Vegas right-side tire that is designed to be more robust. Still in all, Goodyear recommends that teams observe the minimum posted air pressures.
“Being a low wear track, we have worked over the past several years to find a compound that wears at tracks like Las Vegas,” said Greg Stucker, Goodyear’s director of racing. “Excessive heat can be an enemy of the tire and of grip, so wear is a mechanism we use to manage heat and keep the tire in the right temperature range. The other factor we face on intermediate tracks like Las Vegas is teams going below our recommended air pressures in an effort to find grip and speed. As we have since the advent of the 18-inch tire, we have continued to evaluate performance and have designed several updates to our tire constructions to help expand the tuning window for teams.”

Notes – New right-side tire for Cup teams at Vegas: Being on the 18-inch bead diameter tire, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Craftsman Truck Series at Las Vegas this week . . . this is the same left-side tire Cup teams ran at Las Vegas last season, but with a new right-side tire (construction update) . . . Cup teams are also scheduled to run this same tire set-up at Texas, Kansas and Nashville . . . with this 18-inch tire, and its lower profile sidewall, Cup cars do not run inner liners in any of their tires.

Notes – Xfinity, Trucks return to Las Vegas on established tire set-up: Being on 15-inch bead diameter tires, NASCAR Xfinity and Craftsman Truck Series teams will run a different tire set-up than those in the Cup Series at Las Vegas this week . . . this is the same combination of left- and right-side tires teams in both of these series ran at Las Vegas since the beginning of 2022 . . . as on all NASCAR ovals greater than one mile in length, Xfinity and Truck teams are required to run liners in all four tire positions at Las Vegas . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
