72 Nova, with 15x7 rallys (probably a 4.5 backspacing?)

Currently the car has 215/65's on all 4 corners, they look too short and skinny to me.

What is the largest (tallest/widest) Must stay on these wheels
for the front ?
for the rear ?

The front I'd say 235/60-15 and the rear 255/60-15. Some people run 275/60-15's on 15x7 wheels, but they really need to be on 15x8's. The 235 on the front may rub a little though, it's the same height as the 215/56, but about an inch wider. The 255/60 is about an inch taller and about an inch/inch and a half wider. They look good on these cars.

Thanks !!!

The 255/60 for the rear is what I was thinking too.
I have 275/60 on 8" wheels on the rear of my 70 chevelle, and I feel they might look to big on the Nova for my taste.

I would really like to avoid having any rubbing at all, is anyone else running 235/60 on 7" rallys in the front ?

i ran a 275/60 on a 15x7 with stock bsp and it never rubbed..i have a pic if you would like..if it were on an 8" rim you might have some rubbing issues

Were you running air shocks with the 275's ?

My car does currently have air shocks, but that is one of the things I hope to change soon.

NO hotchkis rear dropped mulitleafs in the back, no rubbing issues what so ever

A 275/60/15 tire on a 15 x 8 rim will fit fine without rubbing issues. I've clearanced (rolled) my fender lips but that's more for the 10" wide slick I run when racing the car. The 275/60/15 tire will work fine on a 15 x 7 rim as well, but it looks better on the 8" rim IMHO. Pics are on my webshots page in the link in my sig.

275's fit perfect on the 8" wide rim , but i wasnt sure if it would with the stock rally's

im running 275/40's but i have a different offset
