I know NorCal Nick is running a set of Toyo Mud Terrain 295/70r17 on his LMM. He is also running a set of 2" Fred's spacers. I know he has towed a combined weight of 32,000 lbs with his truck. Hope this helps.

I took the stock tires off and put on 265/70/17 Toyo Open Country A/T's on my 08' LMM and had zero clearance issues. I used 1.5" wheel spacers on the rear and have plenty of room in between the duals with a load on the tires.
I am running 235/80 17s on my work rig. I do not have spacers and I haul 10-12k daily with about 3k worth of bed and tools on the back. I have not had any clearance issues. Here is a Pic the 235s look alot better than the stock "pizza cutters"
