To provide a tire which enables self-repairing at the time of occurrence of puncture by a sealant layer coated onto an inside surface of the tire, includes a sound absorption material and has noise reduction performance, prevents reduction in a function of a sealant by fine pieces of the sound absorption material when a nail penetrates through the tire and the sealant and reaches the sound absorption material, and can maintain the noise reduction performance.SOLUTION: A tire includes a sealant layer and a sound absorption material layer. The tire includes the sound absorption material layer positioned inside a tire, the sealant layer which is positioned between the inside surface of the tire and the sound absorption material layer and is coated to the inside surface of the tire, and a film layer positioned between the sound absorption material layer and the sealant layer.SELECTED DRAWING: Figure 1
【課題】タイヤの内側面に塗布されたシーラント層によって、パンク発生時の自己修復ができる上、吸音材を含んで騒音低減性能を有し、釘がタイヤとシーラントを貫通して吸音材に到達した時も、吸音材の微細片がシーラントの機能を低下させることを防止し、騒音低減性能も維持することができるタイヤを提供する。【解決手段】本発明は、シーラント層及び吸音材層を含むタイヤに関するものであって、タイヤは、タイヤの内側に位置する吸音材層と、タイヤの内側面と吸音材層との間に位置し、タイヤの内側面に塗布されたシーラント層と、そして、吸音材層とシーラント層との間に位置するフィルム層とを含む。【選択図】図1
