The sound absorbing member 3 is formed into an annular shape by joining a body 4 made of a long sponge material. The body 4 has a joint surface 4c where a first end 4a on one side and a second end 4b on another side in a longitudinal direction thereof are joined. The joint surface 4c is inclined with respect to a tire radial direction. A length of an outer circumferential surface 3a of the sound absorbing member 3 is smaller than a length of the inner surface 2a of the tread portion 2.",
