Just got these on a couple of months ago and had a chance to drive them in dry, wet, and snow. So far their traction in both dry and wet is superb, with low road noise and excellent comfort in sub-zero temperatures. Fresh snow traction in 1-3 in. is also excellent and with the Audi Quattro 4WD system, the car is as capable as any jeep or truck. The tread pattern on the tire is also aesthetically attractive, overall an excellent purchase and would buy again over Blizzaks.
I almost want to give 1/5 under wet and snow, but I thought I give this the benefit of the doubt till I get more time on snow. On dry roads, they are quite impressive as they feel more like an all season tire. In snow and slush however, they don't perform a ton better than all seasons. In particular during turn in, my car would severely understeer, and during braking, it tends to slip quite a bit. Being fair however, I have to remind myself that this is a performance winter tire, which may explain some of the qualities I've mentioned earlier. My recommendation is don't buy this tire if you get a lot of snow. Where I am in the city, the roads tend to get cleared pretty fast, so I am sort of ok trading performance for a lack of snow handling.
