    Standard answer for OBS 4x4's is 285/75/16 (about 33x11.50) usually fits. Occasionally someone will need to do a little trimming to keep those wheels from rubbing, so if you absolutely want no risk of rubbing or trimming, you may want to limit yourself to 32x11.50 (265/75/16)

    The 1st number in metric tire sizes is the nominal tread width in mm, so, yes 285's are about 20 mm (~1 inch) wider than 265's.

    nope didnt have to cut a thing. they fit the wheel wells pretty well tho but I had zero issues running them on the stock truck. however, I did have aftermarket wheels, but I believe they were the same specs as stock wheels
