33X12.5 Won't fit our vehicles with any wheel/tire combo unless you...

A: Lift so high your CV boots shred once a month.
B: Body lift and Torsion crank/OME912/Spring Puck.
C: Do a lot of trimming.

I think everyone here did C... I of course had to do more than most because of my offset.

If you're just looking to make your vehicle capable, more than aesthetically mean. Todd Adams probably has the best set up. I think he can go more places than the rest of us.

He has ~32X10.5" tires, on near factory spec wheels. But he has an ARB Locker up front.

I'll answer your questions as well (for me not on Littlte Beasts Behalf)

1. I would have had to cut less, but still would have had to cut.

2. Mine are 20X8.5

3. We all lift our vehicles in the same method OME912 Coils in the rear, and a torsion crank. I did OME rear, with a 1" Coil spacer. And a hefty torsion crank. 15+ I started at ~32" to the bottom of the fender. And now I'm up there... with 33" tires below. (I'll measure if you need me to.

4. I trimmed my fenders and inside the wheel wells as well. Also had to cut off the front of my Sliders. No close ups. But I know LittleBeast has them in his Gallery, I used his images to prepare me for what I had to do.
