Yeah, they are a hybrid tire with a tighter tread patter in the center and a wider lug spacing on the shoulders. Lots of siping and they were made for diesel trucks, so they have a 55k mile wear warranty. I have them on one of my 100 series and a friend has them on his 07 cummins, they are fantastic on both. They look more aggressive in person than they do in pictures - or at least the pictures on the Mickey Thompson websiteSo the mickey thompson ATs do good offroad even though they are all terrains? I like the quite and less wear if I can run AT I will
