PROBLEM TO BE SOLVED: To provide a pneumatic tire having an excellent quietness.SOLUTION: A pneumatic tire comprises a main body of which an outer surface forms a tread surface, and a noise suppression member which is positioned on the inside of the main body in a radial direction thereof. The noise suppression member has a plurality of partition walls which project from the inner surface of the main body toward the inside in the radial direction. The plurality of partition walls is arranged on the inner surface of th main body at intervals in a circumferential direction thereof. This interval is 85 mm or less. The height of each of the partition walls in the radial direction is 10% or more of a tire sectional height. The width of each of the partition walls in an axial direction is 30% or more of the tire maximum width. The specific gravity of the noise suppression member is more than 0.060. This noise suppression member is obtained by crosslinking of a rubber composition. The hardness of the noise suppression member is 70 or more. |
