This is an update after two seasons of summer to winter driving. These tires are still performing great in the snow and mild ice road conditions. I had confidence driving across HYWY 2 to and from Seattle to Yakama over the Cascade Mountains in zero degree down to -10 weather. The conditions changing from wet ice in Seattle, light snow, to slightly icy roads at night, over the pass, and the vehicle never felt like it was losing traction or sliding in any way. I know it was icy, because leaving Leavenworth Washington, several cars driving slow in-front, spun their tires and slid sidewards before gaining control. I had no traction issues and without using my chains. The weather got so cold I had to add air in the tire because of contraction. The tires had lost 7 to 10 psi. I should have taken up the offer from my Ford Dealer to put nitrogen in the tire for extra cost and it would not have been effected by the cold. Once pumped up to 38-40 psi, they road smooth, quiet and returned 21 highway mpg. The wear on the tires are very even. I have not hit the half way wear markers on the tires with 26,500 miles.
