The Blizzak DVM-2 were the only top rated studless tire i could get here in Alaska locally, all the police and troopers use them. They work pretty good. I would recommend them very much, just limit them to wet, snow or slush as they are very soft and will wear down, BUT...they are dual layered, after you wear off most of the soft outer tread the inner tread is much harder and then wears longer as a normal all season tire.
My Mercedes C300 has the AMG package which has different front and rear tire sizes. Blizzak does not make tires that fit my rear wheels. Yokahama made the best rated at the time. Going on my second year.
