Never heard of it. I looked it up, seems legit but don't have any feedback on that one. I, myself, own 33" General Gabber AT2 and I just love them. I'd go the same route again when it's time to upgrade but they don't make it in 37's. So the BFGoodrich AT KO2 is my second prime choice since the thread pattern is similar to the AT2 and I can't complain about it, it does it's job and it does it good.
I also had the chance to experience the well prized Wrangler Duratrack but haven't loved them as much as the AT2 on snow and ice during Quebec winters. So I ended up getting the AT2 and they kept me on track all winter, even in the worst conditions.
Hell, one night me and my buddy were traveling from Montreal to Ottawa and it was a real shit show! Saw at least 10 accidents on the way there and we both had to drive really carrefuly since there was freezing rain falling from up above and the temperature was like -30 degrees Celsius. Let me tell you it was one hell of a drive, a real ice highway to Hell. Took us 3 hours to get to Ottawa instead of the usual 1h.
Good times! XD
