I recently had a Rancho quicklift installed and I wanted to know if I would have any problems if I went to a bigger size mud terrain tire like a 285/70/17, 295/70/17 or a 33x12.5.
I put on some LT285/65 R18's and also had to do the heat mod, to the wheel wells. I know the speedometer is off but haven't really tried to figure by how much.
i would think something around 33" would be fine with the melt mod, but keep in mind tire weight too. the heavier the tire the more that mileage/ power will be hurt.
