AI Technical Summary

Technical Problem

In existing tire designs, stone trapping causes tread deformation, increases rolling resistance and heat generation, and shortens tire service life.

Method used

A tire is designed in which the center groove of the tread is divided into two tread portions, each of which is provided with a preset pattern, including a first and a second longitudinal groove. A raised piece is provided at the bottom of the second longitudinal groove, and the groove bottom is wavy. In combination with multiple transverse grooves and a sheet-like structure, the groove bottom is prevented from stones entering the groove, thereby protecting the groove and improving drainage and anti-skid capabilities.

Benefits of technology

It effectively prevents stone trapping, increases tire service life, reduces rolling resistance and heat generation, enhances wet grip and handling performance, and reduces noise.

Abstract

The utility model provides a tire, the tire is provided with preset patterns, the preset patterns comprise first longitudinal grooves and second longitudinal grooves, the first longitudinal grooves and the second longitudinal grooves extend along the circumferential direction of the tire, and the first longitudinal grooves and the second longitudinal grooves are arranged at intervals along the axial direction of the tire. The first longitudinal groove is close to the tread center groove relative to the second longitudinal groove, and a protruding piece is arranged at the bottom of the second longitudinal groove and extends in the circumferential direction of the tire; the first longitudinal groove is provided with a first groove wall and a second groove wall which are oppositely arranged in the axial direction of the tire, and the side, away from the tread portion, of the first groove wall and the side, away from the tread portion, of the second groove wall are connected to form the groove bottom of the first longitudinal groove. And the projection of the groove bottom of the first longitudinal groove on the tread part is wavy. The tire solves the problem that the service life of the tire is influenced by a stone clamping phenomenon in the prior art.
