Last winter, I got a set of Dunlop Graspic DS-2's like these:

Got them in the same size as the stock all seasons, and they are not studded or studdable. Anyhow, they don't allow studs (on tires that is) here in Ontario.
Weather around here can get as cold as about minus 25 C (-13 F), we usually get a few feet worth of snow, and the shoulders of winter can be pretty wet and slushy.
My wife, who drives the V mostly, is a community nurse, so she drives around the region all day and needs to be able to get around regardless of weather and be safe while doing it.
Very satisfied with them so far, and got them for something like $85 per at Walmart.
