AI Technical Summary

Technical Problem

The existing tires with improved grip performance with all-terrain are insufficient on non-paved road surfaces and are difficult to reliably embed complex road surfaces.

Method used

A specific tread structure design is adopted, including an intermediate pattern structure and a shoulder pattern structure. The intermediate pattern structure consists of a first block and a second block, which extends inclinedly between the first block and the second block, and gradually enlarged first and second ends are provided to increase the grounding area.

Benefits of technology

By increasing the grounding area and improving the drainage and sand discharge performance, the tire's grip performance on non-paved roads is significantly improved, especially on mud and water and fine sand pavements.

Abstract

The utility model provides a tread structure and a tire capable of improving grip performance, the tread structure comprises a middle pattern structure, the middle pattern structure comprises a first pattern block and second pattern blocks, the first pattern block is arranged in the middle of the tread structure, and the two groups of second pattern blocks are transversely arranged on the two sides of the first pattern block at intervals; the first pattern blocks obliquely extend between the second pattern blocks, each first pattern block comprises a first end part which protrudes forwards in the circumferential direction, the transverse width of the first end part is gradually increased in the circumferential direction, each second pattern block comprises a second end part which protrudes forwards in the circumferential direction, the first end part is opposite to the second end part, and the transverse width of the second end part is gradually increased in the circumferential direction. The transverse width of the second end portion is gradually increased in the circumferential direction, the second end portion comprises a third wall and a fourth wall which intersect at the tip end, the third wall obliquely extends towards the outer side from the tip end, and the fourth wall obliquely extends towards the first end portion from the tip end. The tread structure is beneficial for improving the gripping performance of the tire on a non-paved road surface. The utility model relates to the field of tires.
