To provide a tire including a sealant layer and a sound absorbing material layer.SOLUTION: A tire 1 includes: a sound absorbing material layer 3 which is attached to an inner surface of the tire 1; and a sealant layer 2 which is disposed between the inner surface of the tire and the sound absorbing material layer and includes a sealant for attaching the sound absorbing material layer to the inner surface of the tire, wherein the sound absorbing material layer includes a non-woven fabric.EFFECT: The tire has a performance of noise reduction while being capable of performing self-sealing when the tire is punctured, and when the tire is punctured and damaged, only the sealant is introduced to a damaged portion and a constituent component of the sound absorbing material layer is not introduced to the damaged portion, and thus, a problem of air leakage can be efficiently prevented.SELECTED DRAWING: Figure 1
【課題】シーラント層及び吸音材層を含むタイヤの提供。【解決手段】タイヤ1の内側面に付着された吸音材層3と、前記タイヤの内側面と前記吸音材層の間に配置され、前記吸音材層を前記タイヤの内側面に付着させるシーラント(sealant)を備えるシーラント層2とを含み、前記吸音材層は不織布を含む。【効果】タイヤにパンクが発生した時に自己縫合できるとともに騒音低減の性能を有し、タイヤパンク損傷の時、損傷部位にシーラントのみが導入され、吸音材層の構成成分が損傷部位に導入されないようにすることにより、空気漏れの問題を効果的に防止することができる。【選択図】図1
