I have Goodyear Assurance all weather tires on my Subaru Crosstrek, and I feel very confident in the worst of Minnesota and Vermont winter weather. The only down side is that they increase the road noise on dry pavement, which is already a problem in a Crosstrek.

I don't know anything about Subaru's all weather tires, but my inclination is to buy tires from a local tire store, not a multinational car manufacturer.
