Try the General Grabber AT2's from www.tirerack.com
They have the same tread pattern as the BFG AT's. The BFG's have no mileage warantee, the General's have 60,000 miles, and the General Grabber AT2's are about $80 a tire instead of $140. I have them on my Jeep Liberty, and really like them. The reviews on the tirerack website are pretty good too.
