It is funny how many opinions there are of tires. That being said there are a lot of different conditions out there and some tires at that particular day, time, and temperature will just work better...
I was almost all set to buy the Cooper STT Pros, but then found a rebate or sale on my BFG KM3s so I bought those instead. About a month later the offroad group went to an area I had never been at before. All of us aired down on the road and I found it real interesting that a Land cruiser had the SST Pros. Both of us had the same tire size (315/75R16) and both of us aired down to 10 psi. Figure vehicle weights between us were very similar. (he had a lot of crap on board and a diesel engine). He had front and rear air lockers, I have a trutrac/detroit. Very similar and capable vehicles.
Within the first 100 yards there was a drift. The Land Cruiser in front of me slid sideways trying to go thru it and then got stuck. Since there were now tracks going towards the drop off I figured I'd really have problems. Nope. Crawled right thru and there was no slipping to the side.
For the next 6 hours following this guy he was always slipping to the side on off camber sections of the trail. He also got stuck 3 times that day. A 4 door jeep on some Toyo "country" tires got stuck twice. I didn't get stuck or have any issues all day.
After the 3rd time he got stuck I passed him and was behind the Jeep on 40s breaking trail.
The KM3s should not do well in a heavy moisture filled snow but they have proved themselves quite a few times. They don't do well on hardpack snow or ice on the road itself though.

Here was the Jeep getting stuck on Toyos.

I even made it up the other side of this ravine my first try. Didn't think there was a chance...
