NASCAR Sprint Cup Series teams will be using a new compound on all four tires this weekend at Sonoma Raceway.
According to Goodyear, the new tire provides superior grip over the compound employed at the Northern California road course a year ago. The compound was chosen after a late March tire test at Sonoma that involved Marcos Ambrose, Tony Stewart, Kyle Busch, Jeff Gordon and Brian Vickers. The same compound will be used on all four wheels, different from ovals where separate tires are used on right and left sides.
Nationwide Series teams at Road America in Elkhart Lake, Wisconisn, will use the same tires employed on the road course a season ago, again on all four wheels. Goodyear will also bring its wet-weather radials for use at Road America, should NASCAR determine that conditions warrant them.
