The M+S marking are based on a tyre’s geometry and not how well it does on tests actually driving in mud or snow. Tyres with M+S marking are not associated with any mandatory performance test and there is no performance guarantee associated with M+S marked tyres. It says nothing about the tyres rubber compound and how it will perform on snow, slush and ice. Even some high speed rated (Y) summer tyres may have this designation. You will find the M+S symbol on off-road, All-Terrain (AT) tyres and on many ‘summer’ all season tyres. However, there is no performance standard or traction/stopping tests to pass as the M+S designation refers only to the tread pattern. It’s a declaration from the tyre manufacturer that the product can operate in mud and snow better than their regular models. The M+S symbol on tyres is very misleading. A tyre without the 3MPSF marking cannot be marketed as a snow tyre or a winter tyre. The aggressive tread design and siping provides grip and stability in snow and will disperse away water and wet snow slush.Ĭompared to M+S tyres, 3PMSF winter tyres offer superior braking and cornering performance on wet and rough ice, soft and hard-packed snow, and slush. The 3PMSF symbol is standardised and controlled by EU authorities, guaranteeing that the product meets the conditions of rigorous testing and is suitable for operation in difficult weather conditions.ģPMSF marked tyres have been approved through regulation tests to guarantee a higher level of performance under winter conditions stated in the European ECE regulation 117.02.ģPMSF winter tyres are designed to stay flexible in temperatures below 7☌ and provide excellent grip on snow, slush, wet roads and bare asphalt. It states that the tyre’s tread pattern, tread material or structure must be primarily designed in order to provide better characteristics than ordinary tyres in terms of acceleration, traction and stopping under demanding winter conditions, and that it must be verified. The definition of a winter tyre is stated in the European ECE regulation 117.02. Winter or snow tyres that receive the official snowflake marking, also known as the 3PMSF ‘3 Peak Mountain Snow Flake’ symbol, provide verified safety for demanding snow conditions. This page takes you through all you need to know about driving this winter. Numerous types of tyres are used for winter driving, each with varying, and often misunderstood, levels of safety and performance.
