PROBLEM TO BE SOLVED: To provide a pneumatic pressure maintenance tire which refills a pneumatic pressure that leaks during tire traveling with air compression action caused by the bending and stretching motion of a tube connected to a regulator, and maintains the proper pneumatic pressure by itself.SOLUTION: There is provided a pneumatic pressure maintenance tire in which (1) a tube is inserted to a side part where the largest bending and stretching of a tire occurs in order to further improve supply efficiency of air to a tire cavity, (2) air compressed in a travel direction is injected into the tire cavity, outside air is supplied to the tire cavity with a negative pressure formed in the tube located in a travel opposite direction, and a proper pneumatic pressure is maintained, and (3) durability is improved by reducing an exposure portion of a regulator 50.SELECTED DRAWING: Figure 1

    【課題】タイヤ運行中に漏洩する空気圧をレギュレーターと連結されるチューブの屈伸運動によって引き起こされる空気圧縮作用によって補充し、適正空気圧を自ら維持する空気圧維持タイヤの提供。【解決手段】タイヤキャビティへの空気の供給効率をより向上することができるように、(1)タイヤの屈伸が最も大きく発生するサイド部にチューブを挿入し、(2)走行方向に圧縮された空気がタイヤキャビティに注入され、走行反対方向に位置したチューブに形成された負圧によって外部の空気をタイヤキャビティに供給し適正空気圧を維持し、加えて(3)レギュレーター50の露出部位を減少させて耐久性を向上させた空気維持タイヤ。【選択図】図1
