Winter tyre

Winter tyre requirements as well as the definition of a winter tyre differ significantly amongst the national EU laws. Harmonisation of the definition, as a first step and of the requirements as a second in order to align with the EU legislation, would be highly desirable to improve EU road safety.

Tyres marked "M+S" have tread and material designed in a way that driving performance on mud and in snow are better than with normal standard tyres.  This is a Manufacturer's declaration.

From November 2012:

UNECE Regulation 117, to be implemented in the EU through Regulation (EC) 661/2009, requires for snow tyres a minimum level of performance threshold on snow (braking and traction).  If the tyre meets the criteria, it can be marked with the new three-peak snowflake symbol.

However, "M+S" will also remain an allowed marking, but not linked by law to a minimum threshold in winter conditions.


Why Winter tyres? – Because they:

  • Allow better adherence/grip on snow, reduce fuel consumption and provide excellent traction, due to a specially designed tread;

  • Reduce the braking distance by 20% on wet roads

  • Guarantee better driving conditions and increased safety compared to summer tyres or tyres with chains.
