Here's my current '62 that I fitted with a Corvette Rallye 15 x 8 (4.00 B.S.) and M&H Racemaster 275-60-15's. They are DOT-approved and have a true 10 inches of tread. I really like 'em because they hook like crazy, look Nostalgic with their "M&H Racemaster" sidewall lettering and keep the police off my *** by being DOT. Although some of the newer Drag Radials hook like crazy, they just don't look "right" on these early Chevies. Kinda like crossflow radiators, but's that a whole different subject!
