Just a suggestion but if you are going to lift it and wheel it. You should real get some 1.5' or 2" Diff drop brackets. I just install a set because I have had to replace my drive side half-shaft twice and my passenger side once. The half-shafts can be hard to find and are expensive to installed so I would strongly recommend the brackets. Another thing to think about is the bigger the tire the slower ride, unless you change your gear ratios. I have 265/75/17 which is around 31.5" +/-.
