Pneumatic tire

Abstract

A tread surface the tire rotational direction of which is specified in one direction has a center region and shoulder regions on both sides of the center region. Blocks are defined in at least one of the shoulder regions by at least one first circumferential groove which extends in a circumferential direction of the tire, and first lateral grooves which extend in a widthwise direction of the tire and are disposed at predetermined intervals in the tire circumferential direction. Each block includes a tire rotational direction side groove wall surface having an inclination angle alpha , and a tire reverse rotation direction side groove wall surface having an inclination angle beta , and the inclination angle beta is greater than the inclination angle alpha . Each block has a tire rotational direction side edge portion which is chamfered.

Description

Technical field

[0001] The present invention relates to a pneumatic tire, and more specifically, to a pneumatic tire that is intended to improve uneven wear that occurs in loop driving and the like in which lateral acceleration is large during cornering. Background technique

[0002] In the past, various proposals have been made for pneumatic tires having a directional tread pattern that designates a rotation direction as one direction on the tread. Among the pneumatic tires with such a directional tread pattern, there is a pneumatic tire as described below, which is defined by a circumferential groove extending in the tire circumferential direction and a circumferential groove extending in the tire circumferential direction in the shoulder area of ​​the tread. The transverse grooves extending in the tire width direction arranged at intervals are divided into blocks (for example, refer to JP 11-91313 A).

[0003] However, in recent years, the loop track has also been opened to ge...
