摘要

A pneumatic tire and rim assembly is provided in the cavity with a noise damper in which a sponge material extending in a circumferential direction of the tire and having a volume V2 of 0.4 to 20% of entire volume V1 of the cavity, wherein the noise damper comprises a fixing surface fixed to a surface which surrounds the tire cavity, and a free surface directed to the tire cavity, a maximum value of thickness from the fixing surface to the free surface is in a range of 5 to 50 mm, including a thick mountain portion and a thin valley portion; and at least one of outer ends of the noise damper in the circumferential direction of the tire is formed into an inclined surface portion comprising a first inclined surface rising from the fixing surface and a second inclined surface extending from the first inclined surface to the free surface.
