A tire sound absorption part is arranged in a tire, the tire sound absorption part is made of a porous material and provided with a first side and a second side, the first side faces the inner circumferential surface of the tire, and the second side is back to the inner circumferential surface of the tire; the first side is provided with two convex ribs and a groove, the two convex ribs are used for being connected with the inner circumferential surface of the tire, and the groove is located between the two convex ribs; and viewed from the cross section of the tire sound absorption part , the opening of the groove has an opening width, the tire sound absorption part has a maximum width, and the ratio of the opening width to the maximum width is between 20% and 60%. Through the design of the sound absorption piece, vibration of gas in the cavity of the tire can be absorbed, so that noise transmitted to the outside from the tire is reduced.
