> Of course, you could buy used, but I would wager most of the things that make winter tires good in the winter tend to wear out by the time they make it to a used tire shop.
probably not. the main thing that makes a winter tire good in the winter is the rubber compound. as long as the tire has enough tread and is less than about six years old, it will outperform all-seasons in cold weather. every rubber compound has a temperature window where it performs optimally. too cold and the tire is like a rock; it doesn't grip well even on dry pavement. too warm, and the tire is too supple and will wear out much faster. if you expect to do a lot of driving in ambient temperatures much below 40F, you need winter tires. you might get away with all-seasons for a long time, but you probably don't realize how close you are to the tire's limits.
