Storyline – Cup Series back on historic Indy oval: After three years on Indianapolis Motor Speedway’s road course, the NASCAR Cup Series returns to racing on the facility’s historic oval in 2024. The racing surface provides a challenge for these heavy cars, with more lateral slip in the corners compared to the lighter, higher downforce cars that race on the track in May. The Cup tire set-up will be similar to the one Cup teams ran at Pocono Raceway last weekend, but with a couple changes. The Indy right-side tire features a “softer” tread compound to give the cars more grip and introduce more wear, and both will use heavier tread thicknesses..
“We’re back on the Indianapolis oval this week, and our work preparing for this race started right after last year’s race on the road course,” said Greg Stucker, Goodyear’s director of racing. “Once we knew that racing on the oval was a possibility, we held a test last August to establish a baseline with the Next Gen car on the track, since we hadn’t raced on it in three seasons. We followed that up with another on-track session there this June. That tested yielded a new right-side compound for additional grip, and adjustments to the tread thickness on both sides of the car.”
Notes – Cup teams on unique tire set-up at IMS: Being on 18-inch bead diameter tires, NASCAR Cup teams will run a different tire set-up than those in the NASCAR Xfinity Series at Indianapolis Motor Speedway this week . . . this is the first time Cup teams have run either of these two Goodyear tire codes . . . in preparation for this race, Goodyear first held a test on the IMS oval directly after last August’s race on the facility’s road course . . . there was another test at the track this June, with Richard Childress Racing (Kyle Busch), Front Row Motorsports (Todd Gilliland) and Joe Gibbs Racing (Denny Hamlin) . . . with this 18-inch tire, and its lower profile sidewall, NASCAR Cup cars will not run inner liners in their tires.

Notes – Second straight week on this tire set-up for Xfinity teams: Being on 15-inch bead diameter tires, NASCAR Xfinity Series teams will run a different tire set-up than those in the Cup Series at Indianapolis this week . . . this is the same tire set-up that Xfinity teams ran at Pocono last weekend . . . they have also run this left-side tire code with a different right-side code at Darlington and Dover this season . . . as on all NASCAR ovals greater than one mile in length, Xfinity teams are required to run liners in all four tire positions at IMS . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
