jeep gambler wheels

My wheels are 18x8 with zero ET and tire size is 235/55R18. I had to make a little room in all four corners to make them not rub. I can honestly say that this is the extent to what it comes to tire size with stock wheel wells in the back, they're close both on the inside and the outside on an M-body.

I have a 1980 Volare
On the rear; I installed 275/60-15s on 8.5s with a 4.5 bs. I looks pretty good in there, and no touching anywhere. I like the look of a deep-dish,with the offset to the outside; it seems to pop better.

On the fronts I've never installed more than 7s with a near zero offset, so like maybe a 3.75 bs.
