Claims (2)
- タイヤ周方向に延びる主溝によって区画された陸部において複数のブロックがタイヤ周方向に並び、タイヤ周方向に隣接するブロックの間の横溝が前記主溝の20%以上35%以下の深さであり、前記横溝の底部側に前記横溝より幅が狭いサイプが設けられ、
前記横溝がタイヤ幅方向に対して斜めに延びることによって、前記ブロックのタイヤ幅方向一方側に鋭角の角部が、他方側に鈍角の角部が形成され、
前記サイプが、深くなるに従い、鋭角の角部側では鋭角の角部から遠ざかる方向に傾斜し、鈍角の角部側では鈍角の角部の下に入り込む方向に傾斜し、それによってねじれている、空気入りタイヤ。 - 前記サイプが部分的に浅くなっている、請求項1に記載の空気入りタイヤ。
