To reduce a cost while suppressing cavity resonance of a pneumatic tire.SOLUTION: A pneumatic tire 13 with a noise damper member has: a pneumatic tire 10 having a belt layer 30 which is so configured as to include a steel cord; the noise damper member 16 which is formed from a sheet-like member, and has a protrusion 16A which becomes convex toward an interior of a cavity from a tire inner surface side for suppressing cavity resonance of the pneumatic tire 10; a magnet 42 which is attached to the noise damper member 16, and holds the noise damper member 16 on a tire inner surface by generating suction force between itself and the steel cord; a convex portion formed on the tire inner surface of the noise damper member 16; and a recessed portion 48 formed on the inner peripheral surface of the pneumatic tire 10 and fitted with the convex portion.SELECTED DRAWING: Figure 7
【課題】空気入りタイヤの空洞共鳴を抑制しつつ、低コスト化する。【解決手段】制音部材付き空気入りタイヤ13は、スチールコードを含んで構成されたベルト層30を有する空気入りタイヤ10と、シート状部材で形成され空気入りタイヤ10の空洞共鳴を抑制するためにタイヤ内面側から空洞内に向けて凸となる凸部16Aを有した制音部材16と、制音部材16に取り付けられ、スチールコードとの間で吸引力を生じさせて制音部材16をタイヤ内面に保持する磁石42と、制音部材16のタイヤ内面側に形成された凸部分と、空気入りタイヤ10の内周面に形成され、凸部分が嵌め込まれる凹部48と、を有する。【選択図】図7
