We have changed the 245's on our truck to 265's Michelin LTX M&S and keep the front at 65 and the rear at 80. They will fit the same rims. Many of us have made the change to 265's and there are many posts in the past regarding the pros and cons.
The only tire G rated that I know of that SOBs use are Goodyear GB14 RST (I think) and to keep the rating of 3042 lbs keep them inflated at 80lbs. You can go up to 3750 lbs but need to use 110 lbs. inflation which your rims can't handle.
I am in the process of putting on Cooper SRM radial Lt LT235/85 R16 rated at 3042 lbs @ 80 PSI.
Others will probably also reply with their comments. We have a couple of tire people on the forum.
