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 intended to improve uneven wear that occurs during circuit travel with a large lateral acceleration during cornering, or the like. Background technique

[0002] Conventionally, various pneumatic tires have been proposed in which a tread is provided with a directional tread pattern specifying a rotation direction as one direction. Among the pneumatic tires provided with such a directional tread pattern, there is a pneumatic tire in which, in the shoulder area of ​​the tread, there are circumferential grooves extending in the tire circumferential direction, and a groove defined in the tire circumferential direction. The lateral grooves arranged at intervals and extending in the tire width direction are divided into blocks (for example, refer to JP-A-11-91313).

[0003] However, in recent years, the loop track has also been opened to general users, and users oft...
