I was about to buy a set of MTRk Goodyear, but I bought a set of the original Xtreme MT a few years ago. They are not good in very deep mountain snow. Sometimes my Jeep will just stop making forward progress while the rest of the group keeps on moving.
I also sent a stick through the sidewall right next to their Tri-Ply logo Lol!
The closeup picture in the shoot out link above shows the Xtreme MT1. I had to buy one MT2 to replace the one I destroyed. It is a little different. Every other tread edge are now offset/scalloped like most every MT out there. The tread blocks are also stepped like a Cepek Mud Country.
The MT2 is a better tire than the MT1. Would I buy them again? No. I received no help from Procomp on the replacement. Not even a pro-rated price.
The date on the sidewall was just over the 5 yr warranty, even though the tires were not on the Jeep that long.
Something I will always check from now on for any tire I buy. Make sure the date on the sidewall is current, and they have not been sitting in a warehouse for a couple years.
