Abstract

Provided is a pneumatic tire having improved noise performance and improved traveling performance on unpaved roads. In the present invention, a pair of main grooves 10 arranged on the respective sidesof the tire equator CL and extending in the tire circumferential direction are configured such that a series of bent elements 12 formed by connecting at least five linear groove sections 11 via bending points are continuously and repeatedly arranged in the tire circumferential direction. The at least five linear groove sections 11 included in each of the bent elements 12 have three of more different angles of inclination with respect to the tire circumferential direction, and have five or more different lengths.

Description

technical field

[0001] The present invention relates to a pneumatic tire suitable as a tire for running on unpaved roads, and more specifically, to a pneumatic tire having improved noise performance and running performance on unpaved roads. Background technique

[0002] In pneumatic tires intended to run on unpaved roads such as uneven ground, muddy ground, snowy roads, sandy ground, and rocky ground, generally speaking, tires with large groove areas and horizontal grooves and blocks with many edge components are used. surface pattern. In such tires, mud, snow, sand, stones, rocks, etc. on the road surface (hereinafter, they are collectively referred to as "mud, etc.") are bitten to obtain traction performance, and mud, etc. Improve running performance on unpaved roads (for example, refer to Patent Documents 1 and 2).

[0003] Comparing the tires of Patent Documents 1 and 2, it can be said that the tire of Patent Document 1 has a relatively small groove area and also consi...
