1968-1972 C3 Goodyear Speedway Wide Tread Tire F70x15

With the introduction of the C3 in 1968, the engineers from GM chassis design working in conjunction with their counterparts at Goodyear, advanced tire development by designing the F70x15 Goodyear Speedway Wide Tread, and what a tire it is! Although belted bias construction existed, the belted tires caused the Corvette's chassis to begin drifting when cornering at a lower rate of speed. That had to go, the Goodyear Speedway non-belted tire solved the problem. Allowing the Corvette to attain a higher level of performance. The raised white letters version of this tire was only available from the factory from 1969-1972, but will also fit 1968s for a custom look!

Nylon body ply tires were exclusively used on this high performance platform to further enhance impact resistance and heat dissipation - lessons learned from NASCAR, F-1, Indy car, and drag racing. Goodyear F70x15 Speedway Wide Treads are unique in bringing you this total OE package. Maximum performance on the street or judging field, with Goodyear you’re “Doing It Right”.
