PROBLEM TO BE SOLVED: To provide a resonance noise reduction tire to which a noise reduction material is attached by an adhesive layer whose elasticity and adhesive strength are improved, in which detachment of the noise reduction material does not occur.SOLUTION: There is provided a pneumatic tire 1 for maintaining a resonance noise reduction performance up to a wear life without peeling or detachment of a noise reduction material even under temperature change in traveling and deformation due to a load of a vehicle and external impact. An adhesive layer 2 containing a polyether containing an alkoxysilane substituent not in a terminal but in a principal chain, is applied to an inside of an inner liner, and a noise reduction material layer 3 adhered to the adhesive layer 2 is included in a lumen.SELECTED DRAWING: Figure 1
【課題】弾性及び接着強度が向上した接着剤層で吸音材層を付着して、吸音材の脱離がない安定した共鳴音低減タイヤを提供する。【解決手段】走行時の温度変化、自動車の荷重及び外部衝撃による変形にも、吸音材の剥離や離脱なしに摩耗寿命まで共鳴音低減性能を維持する空気入りタイヤ1であって、末端ではなく主鎖中にアルコキシシラン置換基を含むポリエーテルを含む接着剤層2をインナーライナーの内側に塗布し、接着剤層2に付着された吸音材層3を内腔に持つ共鳴音低減タイヤ。【選択図】図1
