I am a mechanical engineer by profession and I live at 7000 ft in Arizona with 108 inches of average annual snow fall- more than Anchorage AK. I can say with high confidence that these tires drastically outperform new BFGR AT Tires in winter driving conditions. The traction is so much better than typical tires that I believe it creates a safety hazard for the driver because they project an unrealistic opinion of road safety. I have had many instances of watching cars slide sideways off the road in front of me at 5 mph on sheets of ice only to find myself thinking what's their problem? Be careful with these tires - you can forget that people with non snow tires won't be able to stop behind you. When I first got these tires I took them out for a snow test in 20 inches of medium weight snow with icy road underneath. The hill I used to test them was a 10% grade hill that had not been plowed as of the city wide closure of all roads to residential travel. In two wheel drive, I wasn't able to push snow too far up the hill and I eventually stopped. in 4 wheel drive however, I devoured the hill and the traction allowed for enough acceleration that I upped the test a notch. I then started backing down at about 5-10mph slamming it into forward trying get the tires into a spin. It was so convincing to feel just a little slip and then feel the g's accelerating up that wicked hill in deep snow. The wear seems to be great since after two seasons now they still look very new. I've also taken them down into phoenix on warm days and I'll admit that they are a bit spongi on dry pavement cornering, but not enough to be concerned.
For winter driving conditions, if you have a 4X4 that you want to behave like a snowcat, or a front wheel drive car that you want to behave like a 4X4, or a rear wheel drive that you want to give a fighting chance to - and on all these awesome winter stopping traction - then buy these tires.
Hats off to the engineers that made this tire!!
