I have limited experience, having only run BFG AT KO2, but they have worked great on both my Gladiator and my CJ7. On the Gladiator they also have a winter in Idaho and were great.
Like many others here I have Toyo Open Country AT III's (35x11.5R17) and they have the snow rating. However we had a very mild winter last year in Midwest Nebraska so I wasn't able to really put them thru their places.
I will say they aren't all that great on icy cobblestone brick streets tho. But to be fair, nothing short of a winter tire is.
