Not that anyone seems to be reading this, but:
O.K. I made a mistake when I mentioned the tire size; they are actually 285/75 16's on the rear and 265/75 16R on the front (that's f'd up)
Here is a pic. I've been trying to figure this out for two weeks and finally asked for help before I spend a lot of money on a lift. I don't want to find out I already have one.
Any input is appreciated
