You can get about 15" of tire width from the frame rail to the fender, if you roll the lip and push the quarter out a little but the real issue is the wheel opening. Without stretching that no way you will get that to fit.

Not sure if that rear axle is too wide, looks that way. More info would be handy, unless you're just kidding. 13x31s ride under my Duster using its original rear rails. Worst case, new rails further inboard, tubs and some under-car cussing...

I have 295/50 on mine and there's loads of room. Well, "loads" relative to most things on an A-body project
