Notes — Cup teams have both "Prime" and "Option" tire set-ups at Phoenix: Being on the 18-inch bead diameter tire, NASCAR Cup teams will run different tire set-ups than those in the Xfinity Series at Phoenix this week . . . similar to the 2025 All-Star race at North Wilkesboro in May and the points-paying Richmond-2 in August, Cup teams will have both "Prime" and "Option" tire set-ups available this weekend . . . on the Prime set-up, this same combination of left- and right-side tires was run at Iowa, New Hampshire, North Wilkesboro, Phoenix-2 and Richmond-2 last season . . . on the Option set-up, these are the same two Goodyear tire codes that Cup teams ran at both North Wilkesboro and Richmond-2 last season . . . with this 18-inch tire, and its lower profile sidewall, NASCAR Cup cars do not run inner liners in any of their tires.

Wet Weather Tires — Goodyear brings white-lettered "wets" 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 the wet weather tire in competition at Chicago in July . . . 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.

Goodyear quote — Stu Grant, Goodyear‘s general manager of global race tires: "Phoenix has been an important track, with it being the site of championship weekend for the past several years.  This weekend we continue with the development of the short track package for the Cup Series, and we will have an Option tire as part of the racing.  We quite successfully ran an Option twice last season so we now get a look at it on a racy, one mile track. Cup teams will have two sets of Options for the race so we‘ll see, like at the second Richmond race last season, how teams will deploy them to best maximize their strategy."
