PURPOSE: To improve the straight advance stability on an inclined road surface of this kind of tire, by suppressing the wandering phenomenon of the tire having an annular recessed part which particularly contributes to the drainage performance. CONSTITUTION: As for a pneumatic tire which is constituted so that a tread 5 is arranged on the outside in the tire radial direction of a carcass 1 which rides over, forming a troidal shape, between a pair of bead cores, and an annular recessed part 6 which is formed by recessing a part of the tread 5 to the inside in the tire radial direction is formed in the circumferential direction of the tread 5, a reinforcing layer 9 having the equal width at least to the opening width of the annular recessed part 6 is installed at the position corresponding to the annular recessed part 6 between the annular recessed part 6 and the carcass 1. |
