Re: Correct tire size for Yenko/Double COPO Camaro
All of the 1969 COPO Camaros that came with the COPO 9737 "Sportscar Conversion" package were equipped with E70x15 Goodyears. No exceptions!
However, the COPO 9737 "Sportscar Conversion" package was also available on the Chevelle with the COPO 427 engine. These cars would have gotten the same 15" rally wheels as the Camaro, but would have come with F70x15 Goodyear tires.
More realistically, I'd guess that at least the rear tires were replaced, after the original tires were trashed, with the F70x15 Goodyear tires as replacemnts. Back then, very few performance would have the original tires last for 28k.
