Excellent posts and replies! Absolutely get winter tires if your driving conditions warrant it! I did so for the first time on my 05' Focus last yr. Needed to buy extra rims (Used $100) and Michelin X-Ice's from DTD. (With the rebates from 3 different sources, very, very reasonably $.) Should have done sooner. Well-worth the piece of mind and the extra measure of safety it provides. (ALSO, consider going slightly narrower width but keeping diameter/load ratings very close.) BTW...the Michelin's IMO (and I haven't driven on other winter tire brands) are superb.
