Can anyone yell me the biggest tire I can fit in the rear of my 69 camaro? And what backspacing?

Thanx

Depends what you are looking for. Do you want 15's, 16's, 17's. Do you want the tire to sit high, gap between top of tire and fender lip, or low with no gap. Are you willing to roll the fender lip? There are lots of variables.
