AI Technical Summary

Technical Problem

Existing tires designed for unpaved roads lack sufficient driving performance and block resistance, particularly on poor road surfaces, and often suffer from sidewall damage from stones and rocks.

Method used

A tire design featuring a tread section with main grooves, shoulder lug grooves, and sidewall blocks, where the sidewall blocks are integrated with continuous narrow grooves forming a block group that enhances block stability and traction through a network of interconnected grooves.

Benefits of technology

The tire design improves driving performance and block resistance on poor roads by maintaining block stiffness and edge action, providing enhanced traction and durability.

Abstract

A tire is provided that offers further improved driving performance on poor roads while also exhibiting excellent block resistance. A shoulder area of ​​a tread section (1) has a plurality of shoulder blocks (12). A side area adjacent to the shoulder area on an outer side in the tire width direction has a plurality of side blocks (13). Two or more shoulder blocks (12) adjacent to each other in the tire circumference direction, and one of the side blocks (13) located on an outer side in the tire width direction of the shoulder blocks (12), are defined as a block group (B). A first narrow groove (21), a second narrow groove (22), and a third narrow groove (23) are provided in each block enclosed in the block group (B).These narrow grooves form a continuous narrow groove group (20) that extends from one of the shoulder blocks (12) enclosed in the block group (B) across one of the side blocks (13) to another of the shoulder blocks (12).
