I have them on the rear on my truck. They seem to be holding up alright so far (only about 10-15,000 miles). I've been more impressed with them than the BFG Land Terrains (Wal-Mart tire only) on the front. I also like them alot more than the Micheln XTs. The Michelns wore down within about 15,000 miles on the rear and the fronts lasted about 25-30,000 miles. When I bought the truck it had some strange off brand tires on it that weren't worth a crap. They got down to about 1/4 thread and had 2 blowouts.
