In my experience with both the mud terrains and the x terrains they just dont seem to wear the greatest. My dad had a set of muds on his 2000 super duty, granted its a heavy truck, but the mechanic at work is real good about maintanence and I have been less than impressed with the way the procomps wear. They always seem to start cupping and wearing awkardly after half of the tread life is gone. Alignment has been good on all said trucks, tires at proper psi, and kept them rotated regularly. I havent had any personal experience with the all terrains, only the muds and x's. So I dont know, theyre cheap enough but try them out they might work alright for you. If tehy dont then dont buy them again.
