“Mud and Snow” (either marked as M+S, M.S or M&S) has been used to indicate winter tires for many years. Although M+S has a legal definition*, it is not related to minimum performance requirements but has been widely used by tire manufacturers to indicate winter products. M+S remains a permitted marking but while M+S tires have better snow traction than regular tires, they do not necessarily pass the legal snow grip threshold.
True winter tires, carrying both M+S and 3PSMF markings, make an important safety contribution in winter conditions, particularly for cars and vans. Goodyear EMEA* strongly recommends that cars and light commercial vehicles get fitted with four proper winter tires as the colder months approach. Indeed fitting M+S tires in the winter is obligatory in some European countries [see section below]. As legislation with the new marking progressively enters into force, national winter tire laws are likely to extend to tires with both the M+S and three peak snowflake symbols.
For commercial vehicles, tires designed for winter conditions are beneficial mainly for mobility, by ensuring traction and hence preventing road blockages. Since the drive axle is the key one for traction of a commercial vehicle, the 3PSMF marking on the drive axle tires is of high importance. This recommendation is valid especially for the single drive axle of commercial vehicles above 44 tons.
