I run a 245 60 15 on a 7" rim with no issue maximum offset is about 3.5", 4" will rub and they will accept as much as 5" of backspace. You can run an 8" with 5" of bs but a 7" rim with 4" of bs will take a lot of tire too.

Won't an 8" rim with 5.5" backspacing fit a 275/60/R15 tire? Thought I read that a while back from a member on here who did that.

I have a 7" rim with 4.5" backspacing I believe and I run a 255/60/R15 on mine. Plenty of clearance on each side of the wheel. I tried a 275/60/R15 but it rubbed.

if im not mistaken it goes tire height/ width/ rim size right? sorry im a newbie haha i like the tire height of the 235 but i really wanna put the widest tire i can under the car and does a rim with 5" of backspacing look "stupid" and is it super obvious that its not a stock rim?

Yes some cars will take more then others, depending on the rear end centering, folks have run 275 60 15.

Nope, not at all you can't really tell because most rims have 3" on the front side so 1 more of bs has little affect. I do prefer the look of a 8" rim that's 4 & 4 with the rear end narrowed.

i was thinking of putting the car up on jacks getting the bare rims on the car and getting them level so i can take a measurement from the outter edge of the rim to the fender lip and from the inner edge of the rim to the frame rail, once i accomplish that i should want the two measurements to be the same correct? so i know they would be as center as possible in the wheel well?

Nope

It's width / height / rim size So a 235 is wider than a 225 And a 235/45 is shorter than a 225/70... Bt the way The height is a factor of the width So a 235/45 and a 225/45 will have a different total diameter and sidewall height..

The first number is the width in millimeters- 235
The second number is the aspect ratio (height) - 60 means the height of the tire is 60% of the width
The third number is rim size

I run 275/60/15's on my '68. They fit fine. If a 235 rubs I think you have the wrong rims with too little backspacing.

I have 15 x 8's with M/T SLR street radials, 28x15x10.
I believe the rims are 5" BS. My fender lip is cut a little, and I have maybe 1/2" on either side.
