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%.

    【課題】空洞共鳴音の低減効果を極大化するとともに吸音材の耐久性を維持することができる空洞共鳴音低減タイヤを提供する。【解決手段】空洞共鳴音低減タイヤは、トレッド部1と、前記トレッド部の両側にそれぞれ配置されるビード部2と、前記トレッド部と前記ビード部を連結する側壁部3とを含むタイヤであって、前記タイヤの内部に配置される吸音材5を含み、前記タイヤの内面により形成される空間の断面積対前記吸音材の断面積の比は23%〜29%であることを特徴とする。【選択図】図1
