To provide a pneumatic tire capable of reducing generation of resonance noise inside a tire.SOLUTION: A pneumatic tire includes a base film (80) mounted on an inner liner (60), and a plurality of porous sound absorption members (100) which are previously mounted on the base film (80) and are arranged at predetermined intervals. Each of the porous sound absorption member (100) has a cross tube having a large number of through holes (130) on a tube wall, and the porous sound absorption member (100) and the base film (80) are composed of resin materials containing polypropylene.SELECTED DRAWING: Figure 2

    【課題】タイヤ内部の共鳴騒音の発生を低減させることができる空気入りタイヤを提供する。【解決手段】本発明の空気入りタイヤは、インナーライナー(60)に取り付けられるベースフィルム(80)と、前記ベースフィルム(80)に予め取り付けられ、所定の間隔で配置される複数の多孔性吸音部材(100)とを含む。具体的な一実施形態において、各多孔性吸音部材(100)は、管壁に多数の貫通孔(130)を有する十字管であり、多孔性吸音部材(100)及びベースフィルム(80)は、ポリプロピレンを含む樹脂材からなる。【選択図】図2
