Know your tire

One symbol does the heavy lifting.

Tires with the three-peak mountain snowflake have passed a standard snow-traction test. M+S is just a tread-pattern marking, and it doesn't meet Quebec's rule.

  • Winter tires: softer compound and deep sipes for snow and ice
  • All-weather: carries the snowflake, stays on year-round
  • All-season (M+S): the legal minimum on BC highways, not a winter tire

Coast to coast
