Rim Size for my 101A2

How can I figure out if 285-75-16s will fit my trailer without rubbing anything or sticking out?
They will be on this rim as well: Pro Comp Alloys Series 7089 Flat Black Wheel (16x8"/8x6.5") by Pro Comp Alloys http://www.amazon.com/dp/B002TUTE06/ref=cm_sw_r_udp_awd_J9titb04TMEPV

I have a tough time with rims, I know very little about back spacing and such.

See how they compare to the stock wheels. On the inside offset, you might get away with another inch, but I wouldn't go more, and that might be too much for off road work, where its likely to rock around more. But those are real fat tires, and they might be too much. The short answer is, pay your money, and see. The more I think about it is, its probably way too much, but that is just a guess. I have had some severe loads on mine (2 tons), and there isn't much room above the tire, to the fender.

My end goal is those rims (available in other widths as well) with a 33" tire on it to match the tow vehicle. Different lug patterns but aesthetically will be great. I could also settle for 32" tires as well if the 33s are going to be to tall. The last thing I want is tires limiting my load capacity.
