It depends on how tall you have it. I have 33x12.5 If I wanted to I could fit 35s. I have a 4in up front and 5 back. If it stock you could fit 33 by cranking on the torsion bars. You may need to lift the rear. The 12.5 width will rub just a little on full lock just like a 1/4 in just back of a little and it would be okay. The 33 will also fit on a stock rim. The fist place I went said they will not fit so they wont sell them to me. But they do no problem. You should change your gear ratios. I had 3.55 and changed to 3.90.
