I have a 285/75 (on the stock wheel) under mine and it fits fine - I'm pretty sure I read that you can fit a 305/70.... As long as your exhaust isn't too close to it.... I think I remember my exhaust being pretty close to the spare - (way back when it was routed that way)

285 75 16 will fit with monster exhaust with an half an inch to spare. I you leave your stock exhaust on you can go to a 295 and maybe a 305. However, I would not go any bigger then the 285 because your hoist will give out.

I have a factory hitch and I have a 285/75/16 with a vinyl cover on it in the factory spot. I have read about guys putting 35's under there as well.
Here is a 315/75/16.

This is where it came from.

I suppose you can swap it out. It is a relatively dinky hoist. If you do not swap it out do like I did. I cabled/locked it to the frame and hitch rails.

I've had a spare 295 BFG All-Terrain under my truck using a stock alum wheel for well over a hundred thousand miles without incident. The key is to make sure the tire snugs up nice and even and seats right. They can get a little off center and go snug, only to loosen up as it seats right.
