The winter tire Dunlop GrandTrek SJ7 is a universal model that is well suited for use in crossovers, SUVs, and pickups. Developed with consideration of Japan's specific climatic conditions, it differs in the use of a number of fairly unusual technical solutions for this brand.
One of these solutions is the rubber compound. Its composition is based on natural rubber and silicon dioxide, which keeps the tread elastic at temperatures significantly below zero degrees Celsius. The structure of the compound contains microscopic crystals that provide additional traction on icy and snowy surfaces, largely offsetting the lack of spikes on this tire.
The tread pattern is a combination of numerous blocks. In the central part, the elements have an arrow-shaped form, which significantly increases their functionality. In particular, such blocks increase traction on snowy surfaces while reducing rolling resistance. In the central part, they form a continuous longitudinal rib that provides directional stability and precise handling when driving at high speeds. The shoulder blocks are distinguished by their almost square shape and massiveness. These elements are extremely resistant to deformation, which, in combination with their large size, increases traction on dry surfaces, providing a "passenger car" character of handling and reducing tread wear. The next important feature of its pattern is the dense lamination with narrow slits with sharp wavy edges. These elements have a "three-dimensional" profile of the walls, fixing them in an open position when in contact with the road surface, which is why the tire demonstrates good traction and braking efficiency on any slippery surface.
Key features of the Dunlop GrandTrek SJ7:
- The rubber compound with microcrystals in the structure provides increased traction on icy surfaces;
- The arrow-shaped blocks in the central part increase traction on snowy surfaces, directional stability at high speeds, and reduce rolling resistance;
- The optimized profile of the shoulder areas, with massive square blocks located in them, gives the handling a "passenger car" character and stability.
