Winter Tire Markings


"Snowflake-on-the-Mountain"
labels winter tires according to the industrial standard that is based on the American definition of winter tires.
These tires perform exceptionally well on snow, icy roads, and at low temperatures in general with regard to safety and control.
In wintry conditions, we recommend the use of winter tires with the "Snowflake-on-the-Mountain" symbol on the sidewall and a tread depth of at least 4 mm.

 
Compared to a normal tire, an "M+S tire" provides improved driving characteristics in snow with regards to driving off or stabilizing vehicle motion owing to its tread pattern, tread compound or construction.  

 


M+S labeling for 4x4/SUV tires

  • Many SUVs and off-road vehicles are equipped with tires that features the 'M+S' symbol. The reason for this is that this vehicle category was initially available in North America where all-season tires with the 'M+S' label are common.
  • The label 'M+S' is officially defined in an EU guideline with the following words: "A tire where the tire tread and structure are designed such that it performs better than normal tires in snow." The performance of tires labeled with the 'M+S' are therefore neither defined nor measured.

  • The performance of winter tires in snow is specified by the "Snowflake-on-the-Mountain" symbol in North America. Only tires that fulfill or exceed these requirements may bear this symbol.

  • Even if 'M+S' labeled tires are considered to be winter tires, as defined by statutory regulations in a number of European countries, we recommend the use of winter tires with the "Snowflake-on-the-Mountain" symbol on the sidewall and a tread depth of at least 4 mm in wintry conditions.
