i'm also running the ATM's. i don't know anyone who's had the MT's, but i love these all terrains. they're smooth, quiet, balanced easily, are wearing well, and survived a week's worth of driving all over johnson valley without any damage period. they went through deep sand, mud, rocks, broken up granite/shale/volcano type stuff, and high speed lake bed blasts while half flat. i couldn't be happier with them.
