Goodyear Racing will bring a new right-side tire for the Monster Energy NASCAR Cup Series race this weekend at ISM Raceway in Phoenix for the Round of 8 finale.
The tire features a slight construction update for Sunday’s Can Am 500 (2:30 p.m. ET, NBC/NBC Sports App, MRN, SiriusXM NASCAR Radio), the ninth of 10 postseason races for NASCAR’s top division. The switch is intended to promote adequate cooling on a 1-mile track where braking and brake heat are often a factor. The left-side tire code remains the same one that has been in place since March 2016.

The decision stemmed from a tire test Oct. 2-3 at the Arizona track. Denny Hamlin, Matt Kenseth, Kyle Larson and Paul Menard participated in the two-day session.
The NASCAR Xfinity Series and NASCAR Camping World Truck Series also will hold races this weekend that will determine the four-driver championship field for each circuit. The tire combination for both of those series remains unchanged from their most recent race at ISM Raceway.
