M+S Tyre Marking

M+S

Mud & Snow

Meets RMA/RAC all-season tyre definition. Self-cleaning tread for average traction in mud and snow at low temperatures.

Standardised by ETRTO or TRA.

Where M+S is on the tyre

Lettered markings read as the tail of the size string, moulded right after the speed symbol. Here it is on an example tyre.

M+S Mud and Snow

A tread-pattern self-declaration, not a tested one. On its own it does not mean winter-certified.
