No way in hell I would want the hassle of changing tires more than twice a year. I find my Nokian 106 tires work as well as anything for winter driving. Clearly, they have limitations on icy trails chewed up by pedestrians. I deal with this by temporarily using alternate routes to bypass severely ice-rutted areas. However, the issue is not traction, but the very rough ride.

These conditions normally persist for only a few weeks in the DC area.
