What Does M+S Mean On A Tire

Standard tires are rated based on many parameters, such as tread life, block structure, or traction on the surface. 

The M+S symbol is also one of the important factors in identifying whether the tire can resist in different environments or not.

What Does M+S Mean On A Tire?

M stands for muddy, while S stands for the first letter of snow. From there,  you can easily understand and conclude the M+S function.

The parameter determines the performance on an uneven surface, exactly muddy and snowy road. In addition, M+S can also be said to serve journeys on mountains and snowflakes.

All-season performance is qualified by the standard of the Rubber Manufacturers Association (RMA). If the tire is marked with this symbol, they are proven to express reliable versatility and traction on mud and snow. 

Tires do not suffer from common problems like humming, slipping in the snow, or lagging on thick muddy areas. Because they can withstand tough areas, tires with M+S engraving are regarded as more durable than regular ones.
