Tire

Abstract

A tire capable of achieving both steering stability and ride comfort is provided. An outer middle land portion 4A demarcated between an outer shoulder circumferential groove 3A and an outer crown circumferential groove 3B and located at an outer side of a vehicle when the tire is mounted on the vehicle, and an inner middle land portion 4B demarcated between an inner shoulder circumferential groove3C and an inner crown circumferential groove 3D and located at an inner side of the vehicle when the tire is mounted on the vehicle, are formed in a tread portion 2. The outer middle land portion 4Ahas first outer middle sipes 5A extending from the outer crown circumferential groove 3B toward the outer shoulder circumferential groove 3A and terminating within the outer middle land portion 4A. The inner middle land portion 4B has first inner middle sipes 5B extending from the inner shoulder circumferential groove 3C toward the inner crown circumferential groove 3D and terminating within the inner middle land portion 4B. An angle theta 1 of each first outer middle sipe 5A with respect to a tire axial direction is smaller than an angle theta 2 of each first inner middle sipe 5B with respectto the tire axial direction.

Description

technical field [0001] The present invention relates to a tire capable of achieving both handling stability and riding comfort. Background technique [0002] Conventionally, tires in which various required performances have been attempted to be achieved in the tire have been known. For example, the following Patent Document 1 proposes a pneumatic tire that attempts to achieve both steering stability performance and riding comfort performance by specifying the length of shoulder lug grooves and the length of shoulder sipes. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-128269 [0004] However, the pneumatic tire of Patent Document 1 has no rigidity difference between the vehicle outside and the vehicle inside when mounted on the vehicle, does not generate self-aligning moment, and may cause response lag during steering. Therefore, further improvements are required to achieve both handling stability and ride comfort. Contents of the invention [0005] The...
