In addition to the M+S marking, winter tires also have the i snowflake symbol on the tire wall. Tires with this marking fulfill the requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) regarding the tire traction on snow and have been especially developed for driving on snow.

The speed index of tires mounted at the factory may be higher than the maximum speed that the electronic speed limiter permits. Make sure that your tires have the required speed index as specified in the "tires" section (Y page 272), e.g. if you buy new tires. Further information about reading tire data can be obtained from any qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. i Tire data is vehicle-specific and may deviate from the data in the example.
