Description

TECHNICAL FIELD

[0001] The utility model relates to the tire equipment technical field, specifically, especially, a kind of middle and high end SUV tire. BACKGROUND

[0002] With the vigorous development of automobile industry and the increasing demand of consumers on automobile performance, SUV model occupies an important position in global automobile market by virtue of its spacious space, good passability and multifunctionality. And tire is the only component of SUV vehicle and ground contact, and the performance of its pros and cons plays a decisive role on the overall driving performance, safety, comfort and durability of SUV.

[0003] In the current tire technical field, although many progress has been made, but for middle and high end SUV tire, there is still a series of problems to be solved. On the one hand, SUV vehicle due to its own weight is larger, the center of gravity is higher, in the driving process, the grip and control stability of tire are put forward extremely strict requirements. Especially in high-speed driving, emergency braking, sharp turning and other working conditions, ordinary tire often can not provide enough friction and lateral support force, easy to cause vehicle out of control, side slip and other dangerous situations, seriously threaten the life safety of driver and passenger. For example, when quickly changing lane on highway or sharp turning in mountain road, insufficient tire grip may make vehicle deviate from the predetermined driving track, cause traffic accident.

[0004] On the other hand, SUV model often needs to deal with various complex road conditions, including rainy day, waterlogged road, muddy road and so on. Some existing tires have obvious deficiencies in drainage performance, when vehicle drives on wet road, water film is easy to form between tire and ground, which will greatly reduce the grip of tire, increase the braking distance of vehicle and make the controllability worse. When driving on urban road in heavy rain or waterlogged rural road, water slide phenomenon caused by poor drainage often occurs, which brings great trouble and safety hazard to driver.

[0005] In addition, the durability and deformation resistance of tire are also key factors affecting its performance and service life. In the long-term use process, tire pattern block is frequently subjected to various external forces, easy to deform, curl and other problems, once pattern block appears curl, not only will reduce the grip and drainage performance of tire, but also will aggravate the wear of tire, shorten the service life of tire, increase the use cost and replacement frequency of car owner.

[0006] In conclusion, to meet the high-performance requirements of mid-to-high-end SUVs under various operating conditions, developing a tire with excellent grip, outstanding drainage performance, good handling stability, effective prevention of tread block curling, and high durability has become an important research direction and an urgent market demand in the field of tire technology. It is of vital importance to improving the overall quality and driving experience of SUVs. Utility Model Content
