Taken from BF Goodrich tyres
Winter markings
Two specific winter markings can be found on tyre sidewalls:
M+S
This marking indicates that, in accordance with European regulations, it is a "snow" tyre. Nonetheless, its performances in winter conditions are not tested.
3PMSF
3 Peaks Mountain Snow Flake: tyres with this marking are designed for snowy roads and offer performance levels confirmed in tests.*
The symbol made up of three peaks and a snowflake (3pMSF) on M+S (Mud & Snow) tyres designates tyres designed for difficult snow conditions.
* Test of braking efficiency in winter conditions using the ETRTO (European Tyre and Rim Technical Organisation) method.
