Embodiment Construction

[0023] The purpose of this specific embodiment is to provide a tire with better handling stability on dry ground, lower tire tire noise, and better safety performance on wet ground.

[0024] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to be essential to the solutions of the invention described in the claims.

[0025] Please refer to Figure 1-Figure 3 , the tire provided in this embodiment is bounded by the centerline C.L of the tread, thus the tread is divided into a vehicle installation outer side 1 and a vehicle installation inner side 2, and the side located on the vehicle installation outer side and the vehicle installation inner side are both set There are a central main groove and a shoulder main groove, and a central la...

Abstract

The invention discloses a tire which is divided into a vehicle mounting outer side and a vehicle mounting inner side by virtue of a center line of a tread, center main troughs and tire shoulder main troughs are sequentially distributed from the center line of the tread to two sides of the tread, a center land part is formed between two center main troughs, middle land parts are respectively formed between two center main troughs and adjacent tire shoulder main troughs, and tire shoulder land parts are respectively formed between two tire shoulder main troughs and adjacent sides of the tread; and each of the two middle land parts is provided with a plurality of first transverse grooves which penetrate through the two sides of each middle land part and are streamlined, the curvature circle-center of the arc of the first transverse groove positioned at the vehicle mounting inner side is positioned at the vehicle mounting outer side, and the curvature circle-center of the arc of the first transverse groove positioned at the vehicle mounting outer side is positioned at the vehicle mounting inner side. By virtue of the arrangement, the tire provided by the invention has better dry land control stability, lower tire noise and better wet land control performance.

Description

technical field [0001] The present invention relates to the technical field of tires, and more specifically, to a tire. Background technique [0002] The tread pattern design of the tire has an important impact on the tire noise and grip, etc. Pneumatic tires that focus on handling, their dry handling stability, tire noise and wet handling safety performance, there will be mutual restraint or even friction between the three. are conflicting, and it is difficult to achieve both excellent performances of the three. [0003] Therefore, how to achieve a good balance between the dry handling stability, tire noise and wet handling safety performance of the tire has become an important technical problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a tire which has better handling stability on dry ground, lower tire tire noise, and better safety performance on wet ground. [0005] ...
