Looking at 37X13.5-18 in Pro Comp Extreme AT and M/T ATZ in the same size. Does anybody have experience with the ATZ in the larger sizes, I do alot of highway driving and don't want to replace tires every 30K. Thanks for any help you can provide, got some good feedback on the Extreme with the search feature but little on the ATZ.

I know the MTZs will last 40K+ and would only think the ATZs would be better, but not for sure.
