Storyline – Concrete + resin will lead to multiple racing grooves at Nashville: Nashville Superspeedway is the longest concrete track on the Cup circuit at 1.333 miles. That surface, along with the resin applied, make it a challenge for drivers and teams to keep up with. Goodyear designs its tread compounds for concrete tracks to rubber-in the surface quickly and consistently, enabling drivers to change lanes as the race goes on in search of grip. Air pressure in the rear tires will be important at Nashville. As teams use air pressure to gain grip, going too far below Goodyear’s recommended levels can cause over-deflection in the tire, which can damage the sidewall of the tire to the point of air loss.
“Laying rubber on the track surface is always the number one goal when we race on concrete,” said Greg Stucker, Goodyear’s director of racing. “Nashville adds resin to the track surface to help accelerate the rubbering-in process, so we should be able to develop multiple grooves over the course of the weekend. When drivers are able to change lanes as the track takes rubber, that leads to more side-by-side racing and a more competitive race.”

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

Notes – Xfinity, Truck teams on on established tire set-up at Nashville: Being on 15-inch bead diameter tires, Xfinity and Craftsman Truck Series teams will run a different tire set-up than those in the Cup Series at Nashville this week . . . this is the same combination of left- and right-side tires teams in both of these series have run at Nashville since 2022 . . . this left-side has been run at Las Vegas (both series), Texas (both series), Kansas (Trucks only) and Charlotte (both series) earlier this season . . . Xfinity teams also ran this right-side at Dover in May . . . 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 Nashville . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
