91 Ford Bronco, what is the largest tire size possible WITHOUT any lift? [picture]?

I had 32/11.50/15 Mud Kings on a stock '90 F-150 which is the same truck with a longer wheelbase. They just barely cleared. 33/12.50's rubbed. If you want a taller tire, there are some brands that come in 33/10.50 sizes. You won't clear anything bigger than that with no lift. They will rub on the inner fenders and the rear corners of the front bumper.
