All-Season vs. All-Weather: Which Is Right for You?

All-season tires are a warm-and-mild-climate compromise — great spring through fall, but they stiffen in real cold. All-weather tires carry the 3-Peak Mountain Snowflake (3PMSF) symbol, meaning they are certified for severe snow service while still being safe to run year-round. For most Greater Toronto Area drivers who want one set of tires and occasional winter capability, all-weather is the sweet spot. For drivers who see heavy snow or want maximum cold-weather grip, a dedicated winter set still wins.
