Jeep Tires

AT, MT, P235, R17, LT315 - there sure are a lot of letters and numbers when looking at what types of tires may be best for your vehicle. And if you are not sure what you want or need, then things can get confusing pretty quickly. Are all-terrain tires the best, or mud-terrain? What about tread patterns and tire size? Will all tires fit a Jeep's wheels, or are different ones required as well as a body lift or lift kit?
