Storyline – Nashville’s track surface provides multiple challenges: Nashville Superspeedway is unique among NASCAR race tracks, being the longest concrete track on the Cup circuit at 1.333 miles. That surface, along with the traction compound that the track applies to it, make it tough for drivers and teams to keep up with. Concrete always poses a challenge in taking rubber, so Goodyear designs its tread compounds to do that as quickly and consistently as possible. With the traction compound being applied just off the apron as well as up near the wall, drivers will likely use the lower lane early in the event and then some will move up the track searching for fresh concrete. Creating those multiple racing grooves is the goal
“This week at Nashville we have a concrete surface to tackle, which means our number one goal is to lay down rubber,” said Greg Stucker, Goodyear’s director of racing. “With the aid of some traction compound and tires being dragged on the surface before we arrive, we will do that fairly quickly. After that, drivers will start to move up the track to find some grip they get from the fresher concrete. Having a full practice with three sets of tires on Friday, teams will get a good idea of how the surface evolves over the course of the weekend, and that will make for a good race on Sunday.”
Notes – Cup teams switch to Fontana/Vegas/Kansas tire set-up for Nashville: Being on an 18-inch bead diameter tire, 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 a different tire set-up than Cup teams ran at this track last season, with construction updates on both sides of the car . . . Cup teams have run this same combination of left- and right-side tires at Fontana, Las Vegas and Kansas earlier this season . . . with this 18-inch tire and its lower profile sidewall, NASCAR Cup cars will not run inner liners in any of their tires in 2023.

Notes – Xfinity, Truck teams on on popular left-side tire 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 series ran at Nashville last season . . . this season, this left-side has been run at Charlotte, Kansas, Las Vegas and Texas already . . . 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.
