Tires...33 ?
I had 32x11.50x15 and they rubbed slightly at full lock. Now I have 31x10.50x15 and they clear. There are tons of tire threads talking a out it. You can probably make 33's work with the right rim spacing.
Your missing your tire width in that measurement, unless your tires are 15" wide. You'll need f250 coils or a levelling kit, very offset rims, and your bumper trimmed and probably spaced out as well. 4x2 trucks sit about 2" lower then 4x4 so it'll be tight.
