Ok i asked earlier what size tires i could fit on a 91 4door 4x4 blazer, and I was told 30'. But what if i use and add-a-leaf kit. Would that make enough room for the 31' tires?

Mike,
I have a 92 4door 4wd and the biggest tire without a lift is the 30 in. The problem with 31's rubbing is not in the rear of the vehicle ( not as bad anyway) it is with the tire rubbing on the back of the front fender ( by the bottom of the door) and rubbing the frame on the inside. Like I posted before all vehicles are different and have different wear patterns however I doubt you would ever get 31's under a stock 4x4 suspension without rubbing,or hacking upo your wheel wells. Best of luck victor
