With no lift 285 on stock rim is perfect fit. Once u lvl it 305/70r16 is ideal. I ran 35 with 10 wide rim and had to take off fender trim n beet in some peices with a mallet. I am switching to 315/70r17 BFG KM2 on 17x9 crager soft 8. I got 2.5" on TT and 1.75" on 2" coil spacer. Leave stock cushion in for full 2". I higly recommend 285/70r17 with stock rim or 8" wide aftrrmarket 16 or 17.
