Dunlop Grandtrek WT M3 – Winter tires for high-performance SUVs

The Dunlop Grandtrek WT M3 is a winter tire for high-performance SUVs. It combines snow traction, cold grip, and water displacement in a tread pattern designed for heavy vehicles. This model is aimed at drivers who have an existing OE approval or specifically want to replace this established winter tread. The winter-oriented tuning is designed to enable predictable reactions when temperature, precipitation, and road conditions change within a short distance. Therefore, when choosing, not only the right size but also the actual use between city traffic, interurban roads, and longer highway stretches counts.

On Swiss winter roads, the tire provides support in snow, wet conditions, and thaw. On black ice and in extreme alpine situations, careful driving and appropriate speed remain mandatory. The MO marking indicates a Mercedes-specific version and should only be used if it matches the vehicle's approval. Before driving to higher regions, it is advisable to also check the weather conditions, local chain requirements, and the remaining tread depth. Tire pressure, tread depth, load, and driving style significantly influence real-world behavior and should be checked regularly.

The Multi-Blade System combines two types of sipes for additional grip edges in the snow. A directional tread with wide grooves displaces water. According to Dunlop, the high-silica compound remains elastic at low temperatures, thereby supporting grip and braking behavior on wet, snowy, and icy roads. The 3PMSF marking confirms the tested snow suitability but does not replace adapted speed or sufficient safety reserves. Which EU label values apply depends on the dimension, load and speed index, and the respective special version.
