In 1965, General Motors requested a lower profile, wider tread tire for the Corvette. Goodyear responded with the Goodyear Power Cushion Bias-Ply Tire. This tire is the most faithful reproduction of those tires available anywhere! The whitewall on this tire measures 5/8" just as the factory originals did in 1966-1967. While it is a correct reproduction for 1966-1967, it will also fit 1965s for the owner who likes the narrower whitewall appearance.
