Abstract

　タイヤ周方向に隣接するジグザグ状のサイプ間に浅溝を設けた空気入りタイヤにおいて、ウェット路面旋回時の操縦安定性の低下を抑え、かつ加硫故障の発生を抑制しながら、金型作製コストを低減すると共にトリム作業を容易にし、かつトリム屑を低減することが可能な空気入りタイヤ、タイヤ成形用金型及び空気入りタイヤの製造方法を提供する。 　本発明の空気入りタイヤは、トレッド面１に溝２，３，４，５，７，９，１０により区分された陸部６，８，１２，１３，１４を有している。陸部６，８，１２，１３，１４のトレッド面部６ａ，８ａ，１２ａ，１３ａ，１４ａには、タイヤ幅方向にジグザグ状に延びる複数のサイプ１５がタイヤ周方向Ｔに所定の間隔で配列されている。タイヤ周方向Ｔに隣接するサイプ１５，１５間に浅溝１６が延設され、その浅溝１６は、浅溝１６の両側に区分される陸部部分ｘ，ｘを分断せずに部分的に連通するように配置されている。
