I put these tires on my FJ Cruiser before going to North Dakota. I'm extremely glad I did. The roads were eventually closed due to blizzard conditions with deep drifts across the roads. I had total confidence with these tires. There was a variety of ice on the roads and there was very little loss of traction.
I tested the tires in snow from one to two feet deep and never got stuck. I was in 4 wheel drive at the time so that helped :)
I have Blizzaks on my Subaru STi and is unstoppable due to great traction and AWD.
