Notes — Left-side tire change for Cup cars at Las Vegas:Being on the 18-inch bead diameter tire, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Craftsman Truck Series at Las Vegas this weekend . . . this is the same right-side tires that Cup teams ran twice at Las Vegas last season . . . this is a different left-side tire code than Cup teams ran at this track last season (compound change for more tire wear and lap-time fall-off) . . . Cup teams ran this same tire set-up on the Charlotte oval, Darlington and Homestead last season . . . with this 18-inch tire, and its lower profile sidewall, Cup cars do not run inner liners in any of their tires.

Goodyear quote — Stu Grant, Goodyear‘s general manager of global race tires: "Generally speaking, the track surface at Las Vegas does not produce a lot of tire wear on its own.  We have worked over the past several seasons at designing our tires to wear more, and we have made a change to the left-side for this weekend‘s Cup race to do just that.  Wear is an important part of racing in that it allows the tires to run 'cooler‘ and produce more fall-off over the course of a run."
