I had high hopes and I'm very disappointed.
They are pretty good in light snow, I have not had the occasion to try on deep snow or ice. They are ok on dry road but they are DANGEROUS on wet road. I have had several close calls on wet roads because they won't break, lock and slide (I don't have ABS). I drive with Goodyear GT Eagle the rest of the year which are very good tires and break well on wet road, I was shocked the first time I slid, now I know and take more precautions.
The ride comfort is however very good compared to my all season tires and they handle good enough on dry for my driving, I did not try to push corners because the sidewalls are soft which makes for the comfortable ride.
I will not buy them again just because they are terrible on wet road conditions.
