Based on our testing and experience, as well consumer reviews, the Continental ExtremeContact DWS is a very solid choice if one is looking for an all-season tire that is good in the winter and performs well the remainder of the year. If you like to drive hard year-round and only want to use one tire, this would be it.
But not everyone should go with this tire. First, it is a performance tire. You'll sacrifice some comfort, some road noise suppression and some longevity to get handling on dry roads. There is no way around it. One tire cannot do everything well. However, if you are looking for a performance tire that is decent in the snow, this would be my pick.
