Tire prices have skyrocketed in the past year. One BF goodrich All Terrain is around 200 dollars here in Atlanta now. There are a few other oddball brands I and a friend have been looking at, Federal Couragia M/T is around 100 a tire. They look awesome but I have no idea how they would hold up. They also make an all terrain Couragia. These could very well wear out in a few thousand miles. I have never had a problem getting them to mount the 31x10.50 15 on the rims. The BFG AT is the best tire out there for all around road, off road, mud traction and comfort but you have to pay an arm and a leg. The 31's may rub a tiny tiny bit in the front at full steering lock without a torsion bar crank. You can go to the bump stops on the back with the most hardcore axle articulation in the rear and they wont rub. I have read conflicting posts that the 33's may or may not rub at certain points.
