Description
Technical Field
[0001] The utility model relates to the technical field of tires, in particular to a snow radial tire. Background Technique
[0002] As the only component of a vehicle in contact with the ground, the tire plays a crucial role in the driving safety of the vehicle. In the northern regions of China, as well as in some parts of Europe and Russia, the winter weather is cold with a large amount of snowfall, and the road surface is often covered with snow. To ensure driving safety, appropriate tires are needed to cope with this road condition. In recent years, with the development of the economy and the improvement of safety awareness, more and more private car owners have begun to consciously replace their tires with snow tires in winter to deal with the snow-covered road surface in winter and improve winter driving safety.
[0003] At present, there are many snow tires for private cars sold on the market, and car owners will also actively replace the tires before winter to ensure driving safety. However, compared with private cars, there are fewer types of snow tires sold for commercial vehicles on the market. Generally, commercial vehicles are longer, heavier in self-weight, and carry a greater load than private cars. Some commercial vehicles adopt a rear-wheel drive mode and are more likely to lose control when driving on the snow-covered road surface in winter.
[0004] Based on this, a snow radial tire is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model
[0005] The purpose of the utility model is to provide a snow radial tire to solve the problems in the background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A snow radial tire includes a tread and a pattern. The tread is symmetrically designed. The pattern includes a first shoulder pattern block and a first middle pattern block. A first shoulder longitudinal groove is provided between the first shoulder pattern block and the first middle pattern block. A first middle longitudinal groove is provided between the first middle pattern block and the first central pattern block. The center of the pattern is a central longitudinal groove.
[0008] On the basis of the above technical solutions, the utility model also provides the following optional technical solutions:

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] 1. By designing the style of the first central tread block as an irregular polygon and providing an inclined groove one between two adjacent first central tread blocks, the present utility model can effectively improve the continuous rigidity of the central tread block, achieving the effect of improving the grip of the tire on snow and slippery roads.
[0018] 2.
