I have found a set of 15" rims, 10" wide with 3and3/4" back spacing. Would these rims fit without using spacers on my GenI? I just thought I could try these with 33s.

These are bit wide for regular width (12.5) 33s IMHO. The backspacing is also pretty bad. It will most likely rub with such little backspacing quite a bit. Spacers will only make it worse.
