What are winter tires? One of the biggest myths about "Winter Tires" is that they are "snow tires". Winter tires are designed for improved traction in cold/wet/slippery conditions. The main factor in all of these conditions is the low temperature. Specific winter tires have design features that maximize their performance in cold weather, not just snow. So if you want maximum performance and the safest cold weather driving possible; snow tires are a huge upgrade. There is a vast difference from a winter tire to an all season tire. A great set of all season tires will be outperformed by true winter tires in the cold and wet weather.
