The sponge member includes: a base portion attached to the tire inner peripheral surface of the tread portion; a plurality of protrusions protruding inward in a tire radial direction from the base portion and extending in a tire width direction, the protrusions being formed at intervals in the tire circumferential direction; and a plurality of recesses formed between the plurality of protrusions. Corner R portions are formed in bottom corners of the recesses. A curvature radius of the corner R portions is larger than 25% of a width of the recesses in the tire circumferential direction.
