I drove on them for one wisconsin winter. The ONLY reason I didn't replace them right away was I was waiting for the buy 3 get one free sale. That was a scary winter. I didn't have any mishaps, but I had no confidence in the tires. They just didnt feel right. Like the truck was floating on the road, more like driving a boat - not quite in control of what the vehicle is doing. I dont know if the problem is the tread pattern, soft sidewalls, or poor rubber compound, but I thought they were terrible especially at higher speeds.
