The present invention relates to a pneumatic tire comprising a sealant layer and a sound-absorbing material layer, comprising: a sound-absorbing material layer positioned on the inner surface of the tire; and the sealant layer is positioned between the tire inner side surface and the sound absorbing material layer and is coated on the tire inner side surface. The sound-absorbing material layer includes a first porous material having closed cells and a second porous material having open cells, and can be self-sealed when a flat tire occurs by the sealant layer coated on the inner side surface of the tire, and can have a performance of reducing resonance sound by including the sound-absorbing material, even if a nail penetrates through the tire and the sealant to reach the sound-absorbing material, the nail can be prevented from being damaged by the nail. And the phenomenon that tiny fragments of the sound absorbing material reduce the function of the sealant can be prevented, and the noise reduction performance can be maintained.

    本发明涉及包括密封胶层及吸音材料层的充气轮胎,包括:吸音材料层,位于轮胎内侧面;以及密封胶层,位于上述轮胎内侧面与上述吸音材料层之间,涂敷在上述轮胎内侧面。上述吸音材料层包括具有闭孔(closed cell)的第一多孔材料及具有开孔(open cell)的第二多孔材料,可以在通过涂敷在轮胎内侧面的密封胶层在爆胎发生时进行自封的同时,包括吸音材料来具有减少共鸣音的性能,即使钉子贯通轮胎和密封胶到达吸音材料,也可以防止吸音材料的微小碎片降低密封胶的功能的现象并保持降噪性能。
