PNEUMATIC TIRE

摘要

A pneumatic tire includes at least three groove rows 21 to 25 at a tread 1 that includes a plurality of both ends closed grooves 2 having both ends closed and extending in a tire width direction. The plurality of both ends closed grooves 2 is arranged at a predetermined distance in a tire circumferential direction. One groove row 23 that includes the both ends closed grooves 2 is disposed on a tire equatorial line E, and at least one groove row 21, 22, 24 and 25 that each includes the both ends closed grooves is disposed at both sides of the groove row 23 on the tire equatorial line E. The both ends closed grooves 2 included in a pair of groove rows adjacent to one another in the tire width direction overlap at end portions in the tire circumferential direction. Each both ends closed groove 2 includes a linear portion 2a and a flexed portion 2b. The linear portion 2a occupies 50% to 90% of a length of the both ends closed groove in the tire width direction. The flexed portion 2b is bent relative to the linear portion 2a at the end portion of the both ends closed groove 2. Thus, a pneumatic tire that achieves excellent running performance on a tarmac road surface and a gravel road surface is provided.
