Problems solved by technology

[0003] However, general high-performance tires have the disadvantages of reduced ride comfort due to small aspect ratio and large block, and greater noise due to tread structure compared with general passenger car tires.
In addition, there is no cut (Kerf) and the pattern formed only by large blocks is accompanied by greater danger in winter use due to the decline in handling and braking performance on snowy and icy roads.
[0004] In order to improve the above disadvantages, the present inventors previously proposed a tread pattern structure for high-performance tires for all seasons (Korean Patent Application No. 2003-0071107) that improves performance on snowy roads and icy roads, but its performance on wet roads is not very good. it is good

Embodiment Construction

[0009] Hereinafter, the present invention will be described in detail based on the attached example drawings.

[0010] Fig. 1 shows a top view of the tread pattern structure of a high-performance tire according to the present invention.

[0011] The tread pattern of the present invention includes lateral grooves 2 continuously arranged in the circumferential direction and continuously extending from the inner side to the outer side. The transverse groove is inclined at 20 to 50° with respect to the tire circumferential direction. The width of the transverse groove 2 is set as follows: Let the center line of the transverse groove 2 be Cl 1 , The center lines of the transverse grooves 2 on both sides adjacent to the transverse groove are Cl 2 , Cl 1 With Cl 2 The middle line (the center line between the lines) at 1 / 2 of the width between the lines is Cl 3 , Cl 4 , The centerline Cl of transverse slot 2 1 And the center line between the line Cl 3 , Cl 4 The connecting line in the tir...

Abstract

The invention provides a weatherable tyre tread pattern structure improving performance of damp road surfaces. Dissymmetry tyre tread pattern of the invention has a transverse slot (2) extending from inside continuously to outside, the width of the slot is wider, the transverse slot (2) is extended as far as inside tyre shoulder (5), so as to improve drainage performance and various performance of damp road surfaces. In addition, the transverse slot (2) of outside is formed to 2/3 (6) width of outside tyre tread to improve touchdown force, which inclines 20 to 50 degrees, tyre capable of attaining optimal steering performance and drainage performance at the same time.

Description

Technical field [0001] The present invention relates to tires for vehicles, and in particular to the tread pattern structure of high-performance tires for four seasons for improving performance on wet roads. Background technique [0002] The definition of high-performance tires, commonly known as UHPT (Ultra Hign Performance Tire), although somewhat different from company to company, generally refers to tires that can run at high speeds and have a small aspect ratio. The pattern feature of such tires is that compared with general car tires, the block is designed to be larger, and the improvement of handling performance and braking performance is pursued. [0003] However, general high-performance tires have the disadvantage that the ride feeling is reduced due to the small aspect ratio and large block size, and the noise caused by the pattern structure is larger than that of general passenger car tires. In addition, the pattern formed only by large blocks without notches (Kerf) h...
