Hey, this sound like a good question for a Canadian, i live in Whistler, BC and drive though the snow alot. I've owned several sets of BF AT's 31x10.5's, 33x12.5's and just got some 33x9.5's AND Let me tell you they all worked excellent in the snow. Ice is Ice and unless you have studs everything is going to slip. I was recently on a trip to Slouquet hot springs where the snow was only about 6-8" for 90% of the trail, but that last 10% got pertty deep and ugly, So i let my buddies ( highly mod'd Jeep's ) go ahead, and break trail. Needless to say they didn't make it far and my "4Runnah" was breaking, like a CHAMP thru 12-16" of fresh on hard pack. Felt like I was a snowmobile with snow coming over the hood, and let me tell you those 33x9.5 BFG AT KO's (pizza cutters) sure did there job and then some. Very pleased with snow performance.
