Default Biggest Tires

Anyone know the biggest tire that you can fit on a stock 81 wheel? I've been at a couple cruise nights and seen some late 70's Vettes with 255 Radial T/A's all around. I definately want the T/A's since it's my daily driver, but I think the look of more rubber is awesome. Can you go bigger than 255? I don't want to change wheels or anything, just the biggest tires on stock wheels w/ no modifications.

I don't know about 80, but I am pretty sure on the early 70's vettes any bigger than 255/60 would require trimming and/or moving some components on the rear.

I have 255/60 rear and 245/60 front on stock rally rims. Fits well, the 255/60 would have rubbed a bit on the front of my particular hand crafted car, but some fit fine.

255/60-15s on mine. Any bigger that that and you're looking at serious rework of the fenders or trailing arms.

Any of you have 76's? I'd like to throw on 255's on my 76, but not sure for that year. ALSO, what's the difference between 70 or 60?

255/60-R15 were optional in '80. That's what I have all round. Any wider and you'll have rubbing problems in the front. I have a couple minor rub spots from sharp turns before I intalled Steeroids.

I had 275/60s on mine before going to bigger wheels. My only issue was the parking brake cable rubbed on the tire. Rod
