Comments: I bought these tires (32x11.5) about two years ago and finally decided to post a detailed review after I had enough time to really experience them. I use my jeep as a DD and spend most of my time on the paved roads but I also do some pretty aggressive offroading on weekends. After 2 years and about 28k miles I still have about 40% tread life left on all 4 tires and they have worn completely even. I'm still able to get through some of the deepest mud and trails around my area and plan on buying the same tire when I move up to 33s.
Snow / Ice: These tires handle good on snowy roads. I live in IL where we see our fair share of snow and ice and these tires do better then I would expect in the worst conditions. No brand of tire performs "excellent" on ice (especially mud terrains) however, the STTs exceed my expectations and plow through deep snow with no problems!
Rain: As with snow, these tires also grip really good in wet conditions and have very minimal slipping. The siping in the tread patterns help tremendously to keep all 4 tires under control and keep you heading in the right direction. I truly believe that driving in dangerous conditions is dependent on 80% driver / 20% tires but it helps to have a tire that really grips and performs well
Mud: I have not been stuck once... that should say it all right there! STTs have very deep lugs that extend all the way down the sidewall and you can really feel these tires pull you through ruts as well as self clean the treads while paddling through thick mud. I've been very happy with how these tires perform offroad and like I said earlier, they still perform good after 2 years.
Road: These tires are built from a harder compound rubber which helps with longevity as well as even wear. I would estimate at least three years or 40k before these tires are done. They are pretty loud and only get louder with more wear but that doesn't bother me. Don't buy a mud terrain if you want a quiet tire
Cooper tires own and make mickey thompson and if you look at the STTs compared to the MTZs, they have very similar tread design and the MTZs are rated as one of the best. I spent a lot of time researching different brands and tread designs before I bought these tires and they have performed better then I ever expected!
