I hear you can get great treadwear out of them if you roatte them every oil change, but that goes for every tire. I've never owned a set personally, so I can't speak to it.

I did own a set of Pro Comp ATs. I got an easy 60k out of them and while they didn't look as good as the BFG, they performed just as well and catching 4WP on their buy 3 get 1 free sale is hard to beat.
