Storyline – Change in Cup tires to introduce more lap-time fall-off at Phoenix: The tire set-up that Goodyear brings to Phoenix Raceway has traditionally lined up with what is run at similar tracks like New Hampshire Motor Speedway and Richmond Raceway. After a test and successful race at New Hampshire this July, NASCAR Cup teams will move to that same set-up for this weekend. The change moves along lines that Goodyear has rolled in at many tracks throughout the 2023 season – the second on the Cup Series’ Next Gen car – that increases grip and tire wear, which leads to lap-time fall-off.
“Increasing fall-off has been something we’ve worked on with a lot of our tire set-ups this season,” said Greg Stucker, Goodyear’s director of racing. “For the group of tracks that Phoenix falls into, we held a test at Loudon earlier in the year and made a change to that set-up for the July race. That race went very well, and after further confirmation at a Richmond test, we decided to bring the new set-up to Phoenix for the championship weekend. Tire wear and fall-off is an important element to good racing because it brings the driver more into the equation with tire management. Those drivers that are easier on their tires early in a run are the ones you see gaining spots later. That means more passing throughout the field and, ultimately, better racing for the fans.”

Notes – Cup teams switch to New Hampshire tire set-up at Phoenix: Being on 18-inch bead diameter tires, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Craftsman Truck Series for at Phoenix this week . . . this is a different tire set-up than Cup teams ran at Phoenix in March . . . compared to what was run in that earlier race at this track, both this left-side and right-side tire feature compound changes to add grip and introduce wear . . . this tire set-up debuted at New Hampshire 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.

Goodyear is the longest-running continuous partner in NASCAR history and has been the exclusive tire supplier to the sanctioning body’s top three national divisions since 1997 . . . 2023 is also a milestone year for Goodyear, marking the company’s 125th year in business dating back to 1898.

Wet Weather Tires – Goodyear bringing wet weather tires to Phoenix: Goodyear will bring its 18-inch wet weather radial tires to Phoenix for the NASCAR Cup cars, should NASCAR determine that conditions warrant . . . Cup teams will have a maximum of four sets of wet weather tires for the event . . . NASCAR Cup teams last ran a wet weather tire in competition at the Chicago street course in July, and last ran it on a short track in the All-Star race at North Wilkesboro in May . . . in addition to the obvious difference of a tread pattern versus Goodyear’s dry weather “slick” tires, the “Goodyear” and “Eagle” lettering on the sidewalls of the wet weather tires is white, not the standard yellow.
