First off, All-Season tires should be appropriately named “3 Season” Tires, our reasoning is:
- All-Season Tires are less effective below 7 degrees Celsius, generally because their compound is harder, decreasing rolling resistance, increasing longevity, and maximizing fuel economy.
- Smaller tread blocks, which reduce noise but also limit ability to grip.
- In the winter, the narrower channels on All-Season Tires can clog with snow, slush and ice creating a slippery surface with less defined tread.
All-Weather Tires are designed for milder winters that do not typically hit too hard, with the ability to handle well in common rain and snow accumulation that does not stick around for too long.
- All-Weather Tires are designed to stay flexible, and the compound stays softer in temperatures both above and below 7 degrees Celsius which ensures stronger grip in many adverse driving conditions like rain, slush, and snow.
- Thicker tread blocks and more aggressive sipe pattern to grip snow and evacuate water and slush.
- All-Weather Tires are 3-Peak Mountain Snowflake Rated.
Winter Tires are designed to be used in climates where snow and ice are constant factors. Areas in mind would be where snow accumulates in large volumes over longer periods of time and the risk factor of ice and other potential hazards are common.
- Winter Tires are designed with a compound that is softer than both All-Season and All-Weather tires to stay playable in temperatures well below freezing.
- Winter tires provide the best braking and handling capability compared to All-Season and All-Weather tires in snowy and icy conditions.
- Deep, chunky tread blocks provide grip, and most aggressive sipe pattern to evacuate as much snow and water as possible for maximized contact with the road.
- Winter Tires are not good for summer use as the softer compound will wear much quicker than All-Season and All-Weather tires.
