PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing road noise, without reducing maneuvering stability.SOLUTION: A pneumatic tire includes one circumferential groove 5 formed in a tread part 1 and extended in a tire circumferential direction, and multiple rows of land parts 6 formed by a circumferential directional groove 5. Each of the land parts 6 of the tread part 1 are formed by laminating a base rubber layer 7 positioned inside in the tire radial direction and a tread rubber layer 8 positioned outside in the tire radial direction. The base rubber layer 7 is constituted of a rubber composition relatively high in hardness. The tread rubber layer 8 is constituted of a rubber composition relatively low in the hardness. A thickness of the tread rubber layer 8 is increased toward the center from both ends in the tire width direction of the land parts 6. |
