It all depends what your plans are for the jeep. You can wedge a 35 in there with no mods. But it obviously isn't ideal. Read around plenty of threads on this topic. Do your research so you only make the purchase once.( that's what alot of people are going to respond with) You also need to consider gearing too. Have fun and be meticulous in your planning. Welcome!
