[QUOTE="XFIRE82, post: 139557, member: 2292"] I didn't think radials were used back then nor that brand from factory. It is old but not correct for the 72. I did a quick search and came up with this info : For 1970-72 Corvettes, the same F70-15 bias ply tires from 1968-69 were used as original equipment. The standard tire was a black wall, with an optional white stripe or raised white letters. The redstripe tire was no longer used. All 1970-72 Corvette tires are of nylon cord construction. The correct white stripe tires used during these years were manufactured by the following manufacturers under the following brand names: the Firestone “Super Sport Wide Oval” and the Goodyear “Speedway Wide Tread”. The correct Goodyear tires should not state “Custom Widetread” or “Poly Glass” as these tires are incorrect. The later issued raised white letter tires were manufactured by the following manufacturers under the following brand names and were either the “Goodyear Wide Tread F70-15” or the “Firestone Wide O Oval”. In 1972 only, a U.S. Royal tire was also used with the “Uniroyal Tiger Paw” lettering. The legitimacy of this tire is still being researched since so few original cars with this tire have been found. The Goodyear striped tires have a 5/16” stripe located 1” from the rim, while Firestone striped tires have a 3/8” stripe located 1 7/8” from the rim. In 1971, new Federal Regulations were instituted that required every tire manufacturer to mold into every tire a new TIN (Tire Identification Number) for traceability in case of a safety recall.
