Did about 25K on BFG MTs before I had to ditch them. I Got a great deal on discount tire's ebay page ($100 coupon) and ended up with 255/75r17 cooper AT3s for $515 shipped. Barely put any miles on them yet, but they're so much quieter and more well mannered on the road/wet. Grip the rock better too. If price and weight are a consideration I'd check them out.
Thanks 4xdog, those do look pretty good! My ideal size would be 33x10.5x15, but I'd have to buy new wheels. You've pushed me towards the pizza cutters though.
