Width is the biggest problem. Forget about any of those 12.50 width tires.
WITH flares I have run 33 x 12.50s without a lift. But that does require trimming at all 4 corners.
Lift does not mean more clearance. Interference points are at the front/rear of the wheel opening. Lift gains clearance at the top, not front/rear. And unless the bumpstop is changed for something taller the up travel will still have the same limits. So the fact you didn't mention lifted or not doesn't bother me.
It's been a long time, but I think about a 32 x 9.50 was about as big as you could go. I think that still took a tad of trimming an inner lip here and there as well. Also at that point it was getting to matter what brand and model of tire as well since the dimensions do not run true to the size.
And we are not even to the wheel size either, and offset. Those are huge when dealing with uncut Broncos.
