450 bucks for 2 tires, plus mounting etc.??? Thats seems quite steep to me. I've heard that BFG all-terrains kick up and spit out a lot of stuff. I think it was Petersons 4-wheel magazine said they are the worst sand and rock throwing tire ever. But anyways. I'm sure they won't bother anything.
You can get 33x12.5x16.5 tires at Sams Club for 135 bucks a piece. They're Dunlop Mud Rovers, and are more aggressive then All-terrains. Plus they have a D load rating. Just thought you'd like to know.
