I mounted a set of 265/70/17 Goodyear Fortera Triple Treads on the rig last week. This is for highway use. I did consider going with a more moderate sized 265/65/17 (30.6") size (hard to find); finding 18/19" wheel takeoffs (small tires, ugh!); or finding a set of Nokian WRs (nearest dealer in Utah). I am going with these 31.7's - retaining the same rough size as my BFG spare, odometer benefits, and same familiar driving height and clearance.
On first evaluation, these tires do feel a bit lighter and a bit tackier on highway pavement. I have not driven in rain or snow yet. Fuel mileage seemed better than the original Dunlops and slightly better than the big BFG's based on a 5 hour trip from Vegas to Phoenix. They are 5/2 ply - okay, but they look prime for a rock slice. Speed Rating is T - 118 mph, good enough for the 3.2 V6. Goodyear rates these 10s for wet, dry, and snow; TireRack puts them in the 9 range.
These should work well on light trails, but I am certain to remount the BFG AT KO 265/70/17's (on separate wheels) when the big trails call.

Gets a bit tighter when the wheel is cranked. But clears!
The BFG's still have the meaner look. Good to keep'em for the trails.
