Sonoma Goodyear Tire Notes:

Teams in the NASCAR Sprint Cup Series will run the same Goodyear tire code on all four tire positions at Sonoma . . . this is the first time teams will be running this code, which came out of a Goodyear test at Sonoma on March 25-26 . . . teams and drivers participating in that test were #9-Marcos Ambrose, #14-Tony Stewart, #18-Kyle Busch, #24-Jeff Gordon and #55-Brian Vickers . . . compared to what was run at Sonoma last year, this tire features a compound change designed to give the cars more grip . . . as on all NASCAR road courses, teams will not run inner liners in their tires at Sonoma. While Goodyear will have wet weather tires at Road America for the Nationwide Series race, it will NOT be bringing its wet weather radials to Sonoma for the Sprint Cup Series race (Goodyear), see tire codes. pressures, set limits and more on the‚ Sonoma Race Info page – Goodyear section.
