As an example, I just installed the following. 17 x 7 with 4" BS, 0 offset with 255/45/R17 on my son's stock 1970 Nova SS. The tires are 26.06" high and have a section width of 10.04". It's close to the fender lip, but won't rub as I can fit my fingertip in between. Quite a bit of room on the inside but the only way to go bigger would be with less offset to pull the tire/wheel in. I test fit an 8" Corvette Rally wheel with no tire during the tire /rim decision stage and I was concerned that it was very close to the shock mount. Without a tire on it I couldn't test the fit against the fender lip, but with about 4 1/2 inches of backspace, IIRC, the tire would have to end up right against the fender.
The 17's moved the inner lip below the shock mount which helped too but the 8" Rally would have fit on the inside, just close. I'm not promoting the bigger size as I voted for 15's but our son wanted bigger. I think it turned out looking very nice. A pic is attached.
Hope this helps.
