M+S Marking (Mud And Snow)
M+S on a tyre stands for mud and snow; it is a manufacturer’s declaration based on tread design, without a required performance test.
What is M+S Marking (Mud And Snow)?
Many SUV summer and all-season tyres carry M+S. It does not prove good winter performance. The three-peak mountain snowflake symbol is the stronger winter mark. The marking is still found on many tyres, so look for both symbols on winter tyres.
How it works
The marking refers to a tread pattern with more and wider grooves than a typical summer tyre.
Why it matters for your car
Do not rely on M+S alone where winter tyres are required by law. Check the tyre for the snowflake symbol when buying winter tyres.
