To provide a tire water pressure test method that can grasp a precursor phenomenon of tire destruction, such as a filament breaking little by little when a tire is stored in an air-filled state.SOLUTION: A water pressure test method includes: (1) a water injection step S2 of pouring water into a tire assembled on a rim; (2) a leaving step S3 of leaving the tire filled with water in water; and (3) a determination step S4 of determining a condition of the tire. In the leaving step S3, a time for leaving the tire filled with water in water is 6 hours or more.SELECTED DRAWING: Figure 2
【課題】空気を充填した状態でタイヤを保管した場合にフィラメントが少しずつ破断していくような、タイヤの破壊の前駆現象の把握が可能な、タイヤの水圧試験方法の提供。【解決手段】水圧試験方法は、(1)リムに組まれたタイヤの内部に水を注ぐ注水工程S2、(2)満水状態の前記タイヤを水中で放置する放置工程S3、及び(3)タイヤの状態を判定する判定工程S4を含む。放置工程S3において、満水状態のタイヤを水中で放置する時間が6時間以上である。【選択図】図2
