Another novelty from the renowned Japanese manufacturer is the winter tire Yokohama Ice Guard IG70A. The model is developed using the most advanced technologies, which are reflected in its working characteristics. Its application area includes crossovers and SUVs, operated both in urban conditions and on light off-road.
The tread of the tire is represented by a non-directional asymmetric structure, which is not typical for winter tires. Its basis consists of both a solid rib and rib structures with a block structure. This combination made it possible to create a large number of gripping edges that effectively fix the contact patch, both on dry asphalt and on ice. Additionally, there is an extensive network of three-dimensional lamellas. They increase stability on wet and slippery roads, ensuring stable driving characteristics and increasing the overall level of safety.
The rectangular elements of the shoulder area, extending to the sidewalls, perform several functions at once. Firstly, they provide stability to the vehicle during maneuvering. Secondly, they improve traction on loose snow. In addition, their part located on the sidewalls helps to effectively counteract stickiness, making handling as predictable as possible.
An important aspect is also the developed system of water discharge channels. They ensure the cleanliness of the contact area, which has a positive effect on protection against slushing and hydroplaning. It is worth adding that the compound contains a significant percentage of silica. Thanks to this composition, it was possible to maximize the adaptation of the tire to a wide temperature range. Therefore, regardless of the external temperature, the tread remains always soft and "grippy". Along with this, the siliceous component in combination with a number of additives increased the resistance to wear. And the dense fit of the entire contact area to the road surface is the basis for the evenness of wear. The result is the preservation of working properties over a long period.
It is not superfluous to note the relatively low noise level, including on dry asphalt. This was achieved by optimizing the arrangement of elements, which minimized air turbulence, which is the source of hum. Therefore, even long trips at high speeds will not be tiresome for passengers and drivers.
The main features of the Yokohama Ice Guard IG70A:
- winter operation on a wide range of crossovers and SUVs of various classes;
- an asymmetric tread with a non-directional structure is especially effective on slippery and snowy roads;
- a multitude of gripping edges created by blocks and lamellas increase the strength of the contact area fixation, maintaining a high level of control even in difficult conditions;
- a compound with silica and a number of high-tech additives remains elastic in a wide temperature range, which has a positive effect on the effectiveness of coupling and traction properties.
