Problems solved by technology

Studies have shown that under the same conditions, the wear resistance and braking performance of the transverse pattern is better than that of the longitudinal pattern; however, the lateral slip of the transverse pattern is greater than that of the longitudinal pattern, and the fuel consumption of the transverse pattern is large, and it is easy to fall quickly

Embodiment Construction

[0015] The centerline CL of the tread of a car radial tire, the tread includes a central pattern block 1, side pattern blocks 2, and shoulder pattern blocks 3, the central position of the central pattern block 1 is the centerline CL of the tread, and the central pattern block 1 is Longitudinal pattern blocks, side pattern blocks 2, shoulder pattern blocks 3 are regularly arranged on the left and right sides from the inside to the outside, between the central pattern block 1 and the side pattern blocks 2, and between the adjacent two side pattern blocks 2 Between two adjacent shoulder pattern blocks 3 are spaced by the same bow-shaped groove 5; between two adjacent central pattern blocks 1 are separated by inclined lateral pattern grooves 12; side pattern blocks 2 and shoulders The blocks 3 are spaced apart by longitudinal circumferential grooves 4 .

[0016] One end of the arcuate groove 5 starts at the interval between the central pattern block 1 and the side pattern block 2,...

Abstract

The invention relates to a sedan tire structure, in particular to a tire tread pattern structure of a sedan tire. The tire tread of the sedan meridian tire comprises central pattern blocks, lateral pattern blocks and tire shoulder pattern blocks, wherein the central pattern blocks are the longitudinal pattern blocks; the lateral pattern blocks and the tire shoulder pattern blocks are regularly arranged on the left side and the right side of the central pattern blocks from inside to outside in sequence; the central pattern blocks are positioned on the central line position of the tire tread; the same arched pattern ditch is spaced between the central pattern blocks and the lateral pattern blocks, between the two adjacent lateral pattern blocks, and between the two adjacent tire shoulder pattern blocks respectively; an inclined lateral pattern ditch is spaced between the two adjacent central pattern blocks; and a longitudinal circumferential pattern ditch is spaced between the lateral pattern blocks and the tire shoulder pattern blocks. The tire tread of the tire adopts mixed patterns, and has the advantages of sufficient braking force, good control performance and elegant appearance.

Description

technical field [0001] The invention relates to a car tire structure, in particular to a tread pattern structure of a car tire. Background technique [0002] In the prior art, there are many car tire patterns, which are usually divided into driving patterns, guiding patterns and the like. The design of tire tread pattern generally adopts the combination of horizontal pattern and longitudinal pattern. In addition to the wear resistance, grip, drainage and other performances, the design of the pattern should also consider the aesthetics of the tire, and require the tire to have a stable Starting and braking performance. Studies have shown that under the same conditions, the wear resistance and braking performance of the transverse pattern is better than that of the longitudinal pattern; however, the lateral slip of the transverse pattern is greater than that of the longitudinal pattern, and the fuel consumption of the transverse pattern is large, and it is easy to fall quickl...
