A lot of lifts have a "recommended backspacing" usually around 4.5". Is that a minimum, maximum, or exact? As I understand it, 0" backspacing would essentially mean that the inside wall of the tire is on the same plane as the axle hub. In that case, there would be plenty of room between the inside of the tire and the shocks/coils/control arms. So I assume that means that less backspacing is better (i.e., more clearance.) Therefore 4.5" would be the MAXIMUM backspacing, otherwise the tire would collide with the shocks/coils/control arms. I've read that the stock Rubicon rims have 6.5" backspacing, which would not work with a lift that recommends 4.5" backspacing. Am I correct, or do I have this backwards?
