Abstract

The invention provides a pneumatic tire which can exhibit excellent performances in all of wet property, uneven wear resistance and straight traveling performance of the tire. A pneumatic tire comprises on a tread surface (1) thereof: a center main groove (2) extending in a tire circumferential direction; a shoulder main groove (3) extending in the tire circumferential direction at a position awayfrom the center main groove (2) in a tire width direction; and inclined grooves (4) formed at predetermined intervals in the tire circumferential direction, wherein each inclined groove includes a first inclined portion (11) extending from the center main groove (2) toward the shoulder main groove (3) while increasing a width thereof, the first inclined portion 11 extending at a first angle alphawith respect to the tire circumferential direction, and a second inclined portion (12) continuously formed with the first inclined portion, the second inclined portion (12) extending at a second angle beta smaller than the first angle alpha with respect to the tire circumferential direction.

Description

technical field [0001] The present invention relates to pneumatic tires. Background technique [0002] Conventionally, as a pneumatic tire, inclined grooves are provided on the tread surface. In this pneumatic tire, the inclined wall portion constituting the inclined groove is inclined at an acute angle with respect to the surface of the land portion (see, for example, Patent Document 1). [0003] However, in the above-mentioned conventional structure, although effective water drainage from the tread surface (wet performance), partial wear resistance of the blocks, and straightness of the tire are taken into consideration, they are not sufficient. [0004] patent documents [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2007-112218 Contents of the invention [0006] The object of the present invention is to provide a pneumatic tire that exhibits unprecedented excellent effects in all of wet performance, uneven wear resistance, and straight running...
