tire size

Hey folks,just joined and really like this site. I have a 66 Coronet 500 and want new wheels and tires. Before I spend the $$$ I want to make sure I get the right stuff. Want 8" 15's on the back and 7" 15's on front What is the biggest tires I can use without modifying or rubbing issues? Thanks in advance

Welcome to Moparts. I don't have an answer for you regarding your early B-body, but someone will chime in with the answer or you can try using the painfully cumbersome search feature.

thanks I hope someonecan lead me in the right direction. I also need info on the backspacing. Thanks again

Welcome to Moparts! I had a '66 Coronet 440 w/ that same combo, 4.25 b/s on the front & 4.5 b/s rear, 225/70-15 on the front & 255/60-15 on the rear, no issues rubbing with no load and I had it kinds low. But if you put ANYTHING in the back seat the top edge of the rear tires would rub the outer wheelhouse. Another issue I had was I know the shocks were shot, maybe the springs too 'cause it sat so low. But that didn't bother me 'cause I did'nt drive it that much and I liked the look.

Hey thanks,I have air shocks on back so maybe those 255's won't rub at all,but still not 100% convinced yet
