A winter tire features the Three-Peak Mountain Snowflake symbol (also referred to as the ‘Alpine Symbol’) on its sidewall. The tire carrying this symbol meets the industry snow traction performance requirements. Winter tires marked with 3PMS symbol must follow the ASTM F-1805 test method on medium-packed snow in standardized testing conditions. Only tires with advanced designs, treads, and rubber compounds can pass this performance-based test. Canadian federal regulation under Transport Canada mandates that all tires that are marked with the 3PMS symbol must meet or exceed a specified minimum threshold.
