Winter tires

Look for the peaked mountain with snowflake symbol when shopping for winter tires. Tires marked with this symbol meet specific snow traction performance requirements and have been designed specifically for use in severe snow conditions.

Tires marked “M + S” (Mud and Snow), or “all season” tires that do not have the peaked mountain with snowflake symbol, may provide safe performance in most weather conditions, but are not designed for snow and ice-covered roads.

At temperatures below 7°C, standard tires begin to lose elasticity, resulting in reduced traction. Winter tires retain their elasticity to grip at much lower temperatures.

Wide, high-performance tires, other than those specifically designed as winter tires, are not suitable for use on snow-covered roads.

As a tire wears, traction is reduced. Tires that are worn close to the tread wear indicators should not be used on snow-covered roads.

To assist you in controlling your vehicle in winter conditions, always install your winter tires in sets of four only.
