They need to be 36-37" tires.

The Nitto terra grappler 2, the cooper Maxx, and the BFG at KO 2 are all in the 36.5-37" diameter. The Nitto has a 50k mile warranty. I have had the BFG AT's on this truck before and got 50,000 miles before switching to the giant Toyo's 37X13.50 96b tires. Although the BFG's at about 40-45 were difficult to keep balanced and hydroplaned too much.

I looked at my mileage log and see that the BFG's were getting me 16-17mpg, these toyos dropped it to 12-13. I've recently redone my front wheel bearing with Spyntec and warn lockout hubs. That alone will be 1.5-2mpg so going back to the far lighter less aggressive tires should put me back into the 17-19 range and a bit better for highway road trips.
