I ran my 33x12.50's with a backspacing of 3 5/8" on 10 " rims with cronic rubbing (stock height) of the front lower fender lip and the wheel well right behind the tire. This was caused mostly by not enough backspacing....
The 15/8 will have less backspacing than stock wheels or any 16/8 you would get later, plus the 33/12.5 is about an inch wider than a 285, so they will stick out more. This will mean it will cause more wear on your steering compontents and possibly cause vibration. Also the 285s(basically the same height as the 33/12.5)will have less sidewall to flex because the wheel itself woould be taller, plus the sidewall on the 285 would be stiffer because of the higher load rating. That means it will handle better, even if you really dont need the higher load rating for towing or anything. It will be a stiffer, tougher, and overall better constructed tire. I debated weather to get 33/12.5 on 15/8 or 285/75 on 16/8 for my chevy z71 when i lift it and decided to get the 285/75 when i do it, even though it will be more expensive. You get what you pay for.
Hope that helps.

MrJoe, with slightly more backspacing and 2" narrower rims, think the rubbing would be much better?
DRED, yeah, I see that little sucker there. My grinding wheel doesn't want to work with the new air hose here, but guy I work with has a Sawzall.
I bet you would have less rubbing than I did, but I think you'll still hit offroad...Mine was fine, as long as I didn't turn slightly and hit a dip....It gave me the "excuse" I needed to con the wife into a lift
