Las Vegas Goodyear Tire Notes

Teams in the NASCAR Sprint Cup and Xfinity Series will run different tire set-ups at Las Vegas this weekend . . . this is the first time Sprint Cup teams have run either of these two tire codes . . . this right-side tire incorporates Goodyear Racing's multi-zone tread technology, which features two distinct tread compounds — one for endurance and heat resistance on the inboard two inches of the tread and one for traction on the outboard 10 inches . . . compared to what was run at Las Vegas last season, this right-side code (D-4690) features the same compound on the inboard, with a different compound for more grip on the outboard . . . this left-side tire code (D-4680) also features a compound change to give more grip.

Goodyear held a tire test at Las Vegas on January 12-13 . . . drivers participating in that test were Kurt Busch, Jimmie Johnson, Matt Kenseth and Brad Keselowski . . . as on all NASCAR ovals greater than one mile in length, teams are required to run liners in all four tire positions at Las Vegas . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
