PROBLEM TO BE SOLVED: To provide a tire capable of reducing cavity noise generated by air vibration inside the tire, which is a kind of noise of the tire, by bonding a sound absorber using a durable adhesive composition that can endure heating and deformation of the tire.SOLUTION: A pneumatic tire 1 includes an adhesive agent layer 2 applied to an inside of an inner liner, and a sound absorber layer 3 attached to the adhesive agent layer 2. The adhesive agent layer 2 includes poly(ether-urethane) having alkoxysilane at both ends thereof. The tire is stable without causing separation of the sound absorber even upon heating and deformation during driving.SELECTED DRAWING: Figure 1
【課題】タイヤの変形及び発熱に耐えられる持続力の強い接着剤組成物で吸音材を付着して、タイヤの騒音のうち、タイヤ内部の空気振動によって発生する共鳴音を低減させたタイヤを提供する。【解決手段】インナーライナーの内側に塗布された接着剤層2と、接着剤層2に付着された吸音材層3とを含み、接着剤層2は、両末端にアルコキシシランを有するポリ(エーテル−ウレタン)を含む。走行時に発熱及び変形にも吸音材の脱離がない安定した空気圧タイヤ1である。【選択図】図1
