Do a search here, you will find that info..
Since you have a heavier 4 door (which sits a little lower than the 2 door), you MAY be able to fit 31x10.50's but you may have to do some trimming, maybe not. If you had a 2 door you could fit them for sure (I have a 94 2 dr, I know) without a lift or trimming. IMO get a el cheapo lift, like coil spacers in front and add-a-leaf in back for 1" or 2" lift. Might look better too, less "stalky".
