My 65 GT convertible has dual redline bias ply tires...I really wanna upgrade to radials. Do I spend the $600 for a set of Coker dual red repro radials, or spend $250 for a set of nice whitewalls at my local Goodyear store? The car is white with white top and red pony interior, ss wheels, etc. Anybody have experience with the dual redline radial repros??? THANKS!!!!
