I'm keeping it simple, I'm going to run 15 X 7 Rally wheels on mine. Probably 235/70/15 on the rear, 225/70/15 on the front maybe a little smaller on the front. I just bought a set that came with 275/60/15 on them but way too tight in the rear due to the stance and no tubs. I have a 75 Nova rear end under it.
