PROBLEM TO BE SOLVED: To provide a resonance noise reduction tire comprising an acoustic material for reducing noise generated by air vibration inside the tire during traveling, stably attached in a tire inner cavity, not allowing heat and deformation during traveling to detach the acoustic material.SOLUTION: A resonance noise reduction tire 1 comprises: an adhesive layer 2 coated on an inner surface of an inner liner; and an acoustic material layer 3 adhered to the adhesive layer 2. A polyether including an alkoxysilane at both terminals contained in the adhesive layer 2 of the resonance noise reduction tire 1 has resistance against heat and deformation to securely hold the acoustic material, as well as a benzotriazole-based ultraviolet absorber further contained in the adhesive layer 2 can prevent aging caused by ozone.SELECTED DRAWING: Figure 1
【課題】走行時、タイヤ内部の空気の振動で発生する騒音を低減する吸音材をタイヤ内腔に備えるタイヤであって、走行時の発熱及び変形にも吸音材の脱離のない安定した共鳴音低減タイヤの提供。【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及び接着剤層2に付着された吸音材層3を有するタイヤ1。接着剤層2が、両末端にアルコキシシランを含むポリエーテルを含むので、走行中の発熱や変形に耐え、吸音材を保持することができ、接着剤層2が更にベンゾトリアゾール系紫外線吸収剤を含むので、オゾン老化を防止することができる共鳴音低減タイヤ1。【選択図】図1
