【課題】熱可塑性樹脂または熱可塑性樹脂とエラストマーからなる熱可塑性エラストマー組成物を主成分とするフィルム2とその両サイドに積層されたゴムシート3A、3Bの3層構造からなるインナーライナー部材1をタイヤ内周面に内貼りし、フィルム2のタイヤ周方向端部がゴムシート3A、3Bを介して重なるラップスプライス部4を有する空気入りタイヤにおいて、加硫成形時のラップスプライス部4の剥がれや、成形後のラップスプライス部4のクラック等のタイヤ故障を抑制する空気入りタイヤを提供する。
【解決手段】ラップスプライス部4において少なくともタイヤ径方向内側に位置するフィルム2の厚さがその端部の先端2eに向かって漸減するとともに、この先端2eがタイヤ径方向外側または内側に向かって屈曲し、かつ先端2eがゴムシート3A、3Bにより覆われていることを特徴とする。
