Winter/snow tires offer superior grip to go, stop, and corner in cold, inclement weather. But they typically have faster treadwear than all-season tires because the tread is specifically designed to bite into snow and ice, and the rubber is formulated to stay pliable at freezing temperatures. Also, winter/snow tires generally take longer to stop than all-season tires on cleared roads. We test winter/snow tires suited to cars, performance winter/snow tires for sports cars, and truck winter/snow tires for pickups and SUVs.
