PROBLEM TO BE SOLVED: To provide a pneumatic tire, particularly, high-performance tire capable of effectively enhancing the draining performance without sacrificing other performances. SOLUTION: A tread part 1 has a pair of circumferential grooves 3, 4 extending along the tire circumferential direction, a number of inclined grooves 7a, 7b extending from the circumferential grooves 3, 4 toward tread grounding ends 5, 6 with inclinations, and a rib-like land part 8 arranged between the circumferential grooves 3, 4. The side walls 8a, 8b of the rib-like land part 8 have pseudo land parts 11 protruding into the adjacent circumferential grooves 3, 4 adjacent thereto in the positions corresponding to the positions 7a1, 7b1 where the inclined grooves 7a, 7b are opened to the circumferential grooves 3, 4, and the surface 12 of the pseudo land part 11 is formed by an inclined surface such that the tire radial distance from the groove bottom of the circumferential main grooves 3, 4 gradually reduces as it leaves the side walls 8a, 8b of the rib-like land part 8. |
