What do the symbols mean on winter tyres?
Winter tyres feature two symbols: M+S and a snowflake on a mountain:
- M+S stands for mud and snow and it indicates that the tyre’s tread pattern and tread compound have been designed to offer superior handling and braking in mud and snow, compared to a summer tyre. The M+S symbol appears on all-season tyres as well as winter tyres.
- The three-peak mountain snow flake (or 3PMSF) means that the tyres has passed a minimum required performance on snow, under EU Regulation 661/2009. This symbol only appears on winter tyres.
