Storyline – Goodyear introduces change to Phoenix tire set-up as the sport works on short track package: Since the Next Gen car was introduced for the 2022 NASCAR Cup season, the sport and its stakeholders have continued to make changes, updates and enhancements. For this week’s race at Phoenix Raceway, Goodyear will continue on a path it began at the race at Martinsville Speedway last October and at a test at Phoenix last December. The change Goodyear has brought forward is to increase the gage – or tread thickness – in its short track tire package. The thicker gage is designed to keep more heat in the tires on short tracks, which is designed to increase lap-time fall-off in order to bring tire management into play and make for even more competitive racing. In testing, drivers also gave feedback that the new tires have more “feel” and increase grip.
“We’ve been working on our tire set-up as the sport has made adjustments to the short track package with this Next Gen car,” said Greg Stucker, Goodyear’s director of racing. “We first increased the gage in the Martinsville set-up last fall and that’s the direction we’re going for the other short tracks on the schedule. NASCAR held a test with six cars at Phoenix in December, which gave us another chance to get on the track and get feedback from the teams and drivers. That test went well from our perspective so we start this season with the new set-up at Phoenix and many other tracks.”

Notes – New tire set-up for Cup cars at Phoenix: Being on the 18-inch bead diameter tire, NASCAR Cup teams will run a different tire set-up than those in the Xfinity Series at Phoenix this week . . . this is the first time Cup teams have run either of these two Goodyear tire codes . . . compared to what teams ran at Phoenix last season, both this left-side and right-side tire have more gage (tread thickness) . . . the increased gage helps keep some heat in the tire and give the cars more grip with this NASCAR short track package . . . Cup teams are also scheduled to run this same tire set-up at Gateway, New Hampshire and Richmond later 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.

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 4 sets of wet weather tires for the event . . . NASCAR Cup teams last ran a wet weather tire in competition at the Chicago street course last July, and last ran it on a short track in the All-Star race at North Wilkesboro last 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.
