I have Procomp Xtreme MT's 35's....the first version. Not impressed. Terrible in the deep snow due to all the side lugs being even, not staggered like most MT tires.
As for their "Tri-Ply" sidewall...I am not sure what that means, but it will not stop a big stick from going right through it. My MT 1's were at 90% and I had to buy one MT2 to replace the destroyed one. Procomp pretty much said "too bad" on any help with a new tire.
Although the new MT2 has a couple added features (staggered/scalloped tread, and stepped lugs like a Cepek Mud Country), but the rest looks the same.
I will not be buying another set due to my experience with the tires, and Procomp.
If you live in the Pacific Northwest, I'll make you a good deal on the 3 and 1 combo! LOL
Tri-Ply sidewall. Check.
