PROBLEM TO BE SOLVED: To provide a pneumatic tire reduced in rolling resistance, and restrained in generation of partial wear such as river wear. SOLUTION: In the pneumatic tire where a tread part of the tire is partitioned into a plurality of land parts by at least one circumferential direction groove extending along the tire equator, at least tanδof the surface rubber of the tread part is 0.02-0.2. An edge part of the land part on the inner side in the tire width direction adjacent to the circumferential direction groove is positioned on the outer side in the tire diametrical direction of an contour line forming a surface of the tread part, and an edge part of the land part on the outer side in the tire width direction adjacent to the circumferential direction groove is positioned on the inner side in the tire diametrical direction of the contour line.
