The invention relates to a pneumatic tire, a method for repairing a perforation of the pneumatic tire, and a vehicle. The repair performance of the perforation is maintained in a pneumatic tire having a porous silencer in the tire cavity. A pneumatic tire according to the present invention is attached to a vehicle provided with a puncture repair kit containing a puncture sealant, and can perform puncture repair by injecting the puncture sealant into the tire. This pneumatic tire is provided with: a pneumatic tire main body (1A) that defines a tire cavity (1B); and a porous sound deadening body (10) that is disposed in the tire cavity (1B). The silencer (10) is not fixed to the pneumatic tire body (1A) in the tire inner cavity (1B) but can be detached from the pneumatic tire body (1A). The air permeability of the sound deadening body (10) as measured in accordance with JIS K6400-7 is 27 ml/cm2/s or less.

    本发明涉及充气轮胎、充气轮胎的穿孔修补方法以及车辆,在轮胎内腔具有多孔质状的消音体的充气轮胎等中维持穿孔的修补性。本发明的充气轮胎安装于具备包含穿孔密封剂的穿孔修补套件的车辆,且能够通过向轮胎内部注入穿孔密封剂来进行穿孔修补。本发明的充气轮胎包括规定轮胎内腔(1B)的充气轮胎主体(1A)和配置于轮胎内腔(1B)的多孔质状的消音体(10)。消音体(10)在轮胎内腔(1B)内不与充气轮胎主体(1A)固定而是能够从充气轮胎主体(1A)拆卸。消音体(10)的依据JIS K6400‑7测定出的通气性为27ml/cm2/s以下。
