发明名称 Pneumatic tire with tread having lateral grooves and sub grooves
摘要 Provided is a pneumatic tire in which left- and right-side lateral grooves extend between first main grooves and second main grooves, and in which left- and right-side sub grooves extend halfway from the second main grooves toward the first main grooves. The lateral grooves and the sub grooves are disposed alternately with each other at predetermined pitches in tire circumferential directions. The left- and right-side lateral grooves respectively include: first groove portions extending from the first main grooves; and second groove portions extending from the second main grooves while curving inwardly toward tire width directions. The left- and right-side lateral grooves are offset from each other in the tire circumferential directions. Opening portions at both ends of each of the lateral grooves, which are opened to the first main grooves and the second main grooves, are shifted from one another in the tire circumferential directions.
