SOLUTION: The tire 1 is structured so that its tread part is furnished with a plurality of circumferential grooves 2 extending in the circumferential direction continuously, and a land row 3 is formed in the central region while shoulder land rows 4 are formed in the side regions. A plurality of recesses and projections continuing in the tire radial direction are formed at the side walls 6 of each circumferential groove 2 partitioning the shoulder land row 4, and at the side walls 5 of the other circumferential grooves 2, a plurality of recesses and projections are formed continuing in the circumferential direction.
