The new tires that Firestone has brought this weekend to the recently-repaved iconic four-mile road course in Wisconsin adds another variable for teams to juggle with. Although overall times were much faster than last year, there wasn’t the expected jump in speed on alternate rubber.
Rossi lapped under Alex Zanardi’s fastest-ever Road America race lap in practice on Friday but did so on Firestone’s harder primary tire. Drivers struggled to improve on the softer alternate rubber, but Rossi believes there are gains to be made ahead of qualifying tomorrow.
