I have 275/40/18 on mine and there's a finger's-width of room between the outside sidewall & outer (inner) fender, and to the best of my recollection there was still about an inch or more between the inner sidewall and framerails/leafs... I say do a 275 for SURE, maybe even a 285 or 295... I can take pics of the 275 fitment for you tonight...

These are a 275 on an 8" rim (ideally I woulda picked up a 9.5) with an equivalent backspacing of 4.375" on a drum rear end.
A piece of 1/4" MDF barely hangs in on the outside, and there's a constant 1" clearance all around the inside. I'd say if you were confident the rear wasn't going to float side-to-side too much, go with some more backspacing and do a 295 filling up the inboard side!!
If not, could stay conservative and do a 285 with 0.25" less backspacing to bring the rim inboard a bit more.

you need a 15x8 5" B/S if you have a stock width rear, if its too tight you can push it a bit and do a 4.5 B/S on a 15x7 & a 275/60/15 but a 8" rim will be better i have done both, right now i just switched rear ends 12 bolt to 9" with discs, was same i width , i had a 255/60/15 street tire on it with a 4.5 b/s which fit ok but wouth clear my new wilwoods and probally wouldnt of worked witha 275 i had other rims (same ones) but in a 5.5 b/s and they just barely contact the shock stud(on the traction bars) so .5" spacer put it perfect....= you need a 15x8 with a 5" b/s to run a 275/60/15, i have done several rims/back spacing on my nova...

I will have to find the pics, but i have The DSE kit in my car , they told me that I could only run a 10" wheel and a 295. I had a MT 325/50/15 drag radial on the rear of my car on a 10" rim if would have had a .25 more back spacing they would have cleared with 0 rubbing.

use 5.5" B/S wheels and a .5" SPACER thats what i'm doing, i tried a 15x8 with a 4.5" B/S they will fit a 255/60/15 but a 275/60/15 will rub on the outter edge/qtr panel...even if trimmed/ rolled, novas are a bit tight, B/S has to be right

I agree on the 8", 5.5 bs as thats what I ended up doing too. A 4.5bs wouldnt work on my car as it rubbed the outside wheelwell pretty bad. Every car is different though and should be checked. Its sure easier to make a 5.5" bs wheel a 5"bs wheel by using a spacer......the same cant be said for a 4.5" bs wheel if it ends up rubbing the wheelwell.
