UPDATE: We had about 8 inches of snow on the ground this past weekend and I was pleasantly surprised how well the A/S 3 performed.
My 1/8th mile driveway had tracks from neighbor's cars, which I used to get out to the road. Coming back I was more confident and made my own fresh tracks in 6-8" no problem- up and down hill.
I was able to accelerate, brake and steer much better than I would expect from these tires. On the road with mixed snow, ice and slush they were very stable and predictable.
They are not as good as a snow tire, but running a V-rated 215/45-17 all season tire year-round, that actually works in snow, makes me a happy camper.
