The winter tire Yokohama Guard iG65 has replaced the iG55 model, highly valued by motorists in Northern Europe and Russia, on factory assembly lines around the world. The new model has surpassed its predecessor in most operational properties, thanks to a large number of innovations. In essence, the tire was designed from "scratch".
Saw-toothed central rib
The entire central part of the tread is a very wide solid longitudinal rib. This element has a composite structure, containing a large number of blocks connected by rigid bridges. Their complex polygonal shape and massive size provide the contact patch with numerous and extended faces that prevent longitudinal skidding during acceleration and braking.
Interlocking stepped lamellas
Another important innovation is the stepped lamellas. When in contact with the road surface, they form numerous faces that the tire grips onto the icy surface. The stepped shape of these cuts, as well as their arrangement, in which the blocks deform in a certain way, additionally enhances traction.
Shoulder blocks with sharp side edges
The blocks located in the shoulder zones have a number of original features. One of them is the sharp side edges. They prevent skidding on snow and ice, literally digging into their slippery surface, thereby ensuring additional stability during maneuvering. This effect is further enhanced by the numerous edges formed by the vertical and horizontal grooves.
Main features of the Yokohama Ice Guard IG65 tire
- a wide saw-toothed longitudinal rib in the central part;
- a two-layer tread, where the inner part provides reliable retention of the studs;
- interlocking stepped lamellas improve longitudinal traction on ice and snow;
- sharp edges of the shoulder blocks with drainage grooves prevent lateral skidding;
- wedge-shaped drainage grooves prevent aquaplaning and slash-planning;
- the rubber compound does not change its elasticity over a wide temperature range, ensuring stable traction properties.
