Re: 1975 Highboy tire size?
Well, there's more than just the outer diameter in this. With the throw of my rims, I have about 4" between the wheel well and the tire, if your rims tuck you tire in further, you might not have the clearance, but I'm assuming your rims have similar dimensions as mine, they're designed to go on a highboy.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
