PROBLEM TO BE SOLVED: To provide a cavity resonance noise reduction tire capable of maximizing the effect of reducing cavity resonance noise and simultaneously maintaining the durability of a sound-absorbing material.SOLUTION: A cavity resonance noise reduction tire comprises a tread portion 1, a bead portion 2 disposed at each side of the tread portion, and a sidewall portion 3 for connecting the tread portion and the bead portion. The tire further comprises a sound-absorbing material 5 disposed inside of the tire. The ratio between the cross-sectional area of the sound-absorbing material and the cross-sectional area of the space formed by the internal surface of the tire is 23-29%. |
