What is Full traction's recommended tire size, width, and backspacing of rims for the 2 and 3 inch lift??

I have a set of 35X12.50x15 MTR's that I plan on running. I have to see what lift and wheel selection is out there for it to work.

For the 2" lift, I'm pretty sure they recommend a 33x12.50 max tire size and on the 3", a 35x12.50. As far as wheels go, not all 15" wheels will fit on the JK but the ones Full Traction shows is a 15x8 - 5x5 bolt patter with 3.75" of back spacing. The factory back spacing is 6.25" and I can tell you first hand that you will need at least 5.5" of back spacing or less in order to keep your 12.50 tires clear of the rear sway bar.

Is that backspacing on the axle or on the wheel?:confused: Since I was planning on the larger BFG 285/70 17s on the stock 17x7.5 rims, will that screw me up with the 2" lift?
