Winter tires

Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking.on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and have
been designed specifically for use in snow
conditions. Use of winter tires is the only way
to achieve the maximum effectiveness of the
®
ABS and ESP in winter operation.
For safe handling, make sure that all mounted
winter tires are of the same make and have the
same tread design.
