Tire size with 4" lift

I have a 90 2dr with a 4" lift. I was just given (for free) an almost new set of 33 x 12.5 x 15 BF Goodrich Mud-terrain T/A.

Do you think they will fit?

They will fit easily if you trim the fenders for YJ, TJ, or similar flares. They probably could fit if you trim the inside of the fenders (below/inside the stock flares) and bumpstop them.

If you run stock wheels you will probably have significantly more issues with clearance while turning and/or stuffing. They would work much better on a wheel with more off set (3.75-4.25 of Back Spacing).
