I have 20x10 with -24 offset with 3 1/2 leveling kit/lift. I had to trim inner fender quite a bit and will most likely trim bumper support. Rubs occasionally when turning and I hit a bump just right.
I have toyo AT2's on my f350 and they were 35 but actually 34.5" I ordered 37 1350 18 toyo mt's and its a HUGE difference side by side. Toyo does measure actual 37inches but it was more of a difference than I expected. FWIW
