To provide a tire which is self-sealing when puncture occurs, and which exhibits noise reduction performance.SOLUTION: A tire 1 comprises: a sound-absorbing material layer 3 attached to an inside surface of the tire 1; and a sealant layer 2 which is interposed between the inside surface of the tire 1 and the sound-absorbing material layer 3, and comprises a sealant for attaching the sound-absorbing material layer 3 to the inside surface of the tire 1. In the tire 1, the sound-absorbing material layer 3 is attached onto the sealant layer 2 coated on the inside surface of the tire 1, so that the tire is self-sealing when puncture occurs and exhibits noise reduction performance. Further, fluidity of the sealant is improved by reducing a specific surface area between the sealant and the sound-absorbing material, according to an increase in average pore size of the sound-absorbing material.SELECTED DRAWING: Figure 1
【課題】パンク発生時の自己修復(セルフシーリング)ができると共に、騒音低減性能を有するタイヤを提供する。【解決手段】タイヤ1は、タイヤ1の内側面に取り付けられた吸音材層3と、タイヤ1の内側面と吸音材層3との間に配置され、吸音材層3をタイヤ1の内側面に取り付けるシーラント(sealant)を有するシーラント層2とを含む。タイヤ1は、タイヤ1の内側面に塗布されたシーラント層2の上に吸音材層3を取り付けて、パンク発生時の自己修復ができるとともに、騒音低減性能を有し、吸音材の平均気孔サイズを増加させることにより、シーラントと吸音材との間の比表面積を減らしてシーラントの流動性を向上させた。【選択図】図1
