Along with a new rules package, Cup teams will have a new left-side tire at Atlanta Motor Speedway this weekend.

NASCAR’s new rules package includes a tapered spacer that will limit engines to 550 horsepower, an 8-inch spoiler, a longer 2-inch splitter overhang and a radiator pan that is 37 inches at the front and tapered to 31 inches at the rear.

The left-side tire Goodyear will bring to Atlanta features a construction update that aligns Atlanta with what is run at other speedways. The right-side tire remains a multi-zone tread tire. This is the same right-side tire teams have used at Atlanta since 2016. The tire setup came from a test last year with Ross Chastain (Chip Ganassi Racing), Erik Jones (Joe Gibbs Racing), Ryan Blaney (Team Penske) and Paul Menard (Wood Brothers Racing).

Xfinity and Gander Outdoors Truck Series teams also will have a new left-side tire compared to what each series ran at Atlanta last year. As in Cup, the change to the left-side tire for Xfinity and Truck teams is a construction change.
