All terrain tires and i want to keep my Stock wj rims ( they have 245/70/16 on them now ) and Im not sure if i have to Have a lift for the BFG all terains but im guessing i do. I also saw 2" bb? not sure what they are but i saw a similar jeep to mine with a 2" bb and the bfgood tires that i want. Is that a Spring Lift so i can fit larger tires on basically?
