Journal Update

Although the C2 had an outstanding chassis update, it retained the 6.70-15 bias-ply tires from the previous generation. As horsepower increased, a lack of traction became a real problem. The initial solution involved a new tire size, which provided a slightly shorter sidewall and a wider contact patch. Introduced in the 1965 model year, the 7.75-15 size became the standard tire size for the Corvette. In terms of sidewall styling, the one-inch whitewall remained in the lineup from 1963 to 1965, then reduced to 5/8-inch for 1966-1967. The 1965 and 1966 models offered special gold stripe tires. By 1967, the gold stripes had become red, and the 7.75-15 sizing remained in place for the final year of C2 production. Black wall tires were also an option in 1963-1965 (Option Code P91).
