215 is a small tire, won't do much for your groud clearance, probably limiting your off-highway experience to just gravel roads. You can fit a 235 or even 245 on a stock TJ. Most use the standard tire sizes, ie. 31x10.5, 30x.9.5, etc.
You talking on your TJ or XJ? What brand/model tire you looking to use?[addsig]
