High-control low-noise pneumatic tire

Abstract

The invention discloses a high-control low-noise pneumatic tire, which relates to the field of pneumatic tires, and comprises a tire body, the tire body comprises a tire tread, and grooves formed in the tire tread along the circumferential direction and the axial direction of the tire divide the tire tread into a plurality of block-shaped patterns. The high-control low-noise pneumatic tire has a simple structure. A set of protruding blocks are arranged in circumferential grooves in the inner side and the outer side in the radial direction of the tire, the parameter range of the width, the depth and the number of the protruding blocks is limited, meanwhile, asymmetric pattern design is adopted for the tire tread, and transverse grooves in the crown portion of the tire tread are all formed in a corner cut and thin groove combined mode. And the parameter range of the chamfers and the fine grooves is limited, so that the relationship among all performances of the tire can be effectively balanced, and the tire can have excellent wet land, noise performance, control stability and safety performance at the same time.

Description

technical field [0001] The invention relates to the field of pneumatic tires, in particular to a high-handling and low-noise pneumatic tire. Background technique [0002] With the continuous growth of the use of passenger cars, the use environment that vehicles need to deal with is becoming more and more complex, which requires more and more stringent requirements on the various performances of tires. Therefore, it is required that the design of tire tread should not only consider safety, Wet performance, noise and other performance, in addition to consider the aesthetics of the tire. As we all know, for the wet performance of tires, the wet performance is usually improved by increasing the width and number of circumferential and transverse sipes, and increasing the sea-to-land ratio of the pattern. But blindly doing so will affect other performance, such as noise, safety, wear and so on. [0003] In view of the above background problems, the current commonly used design m...

Problems solved by technology

[0004] Through the above-mentioned many improvements on the tire surface, the existing products cannot achieve a reasonable match between the main performances of the tire. For example, adding a closing device to the bottom of the circumferential groove, the groove design can weaken the main The noise generated by pattern resonance in the pattern groove, but it does not take into account the influence of the entire tire pattern on other performance (such as wet grou
