PROBLEM TO BE SOLVED: To incorporate an air maintenance feature within a tire that will self-maintain the tire air pressure in order to compensate for any reduction in tire pressure over time.SOLUTION: An air maintenance tire assembly comprises: a tire having a tire cavity, and first and second sidewalls 18; an elongate groove 32 located within the first sidewall 18, the groove comprising an elongate channel 34 and an elongate groove access passage 40 extending at an incline from the channel 34 to an access opening 42 located at an outward surface 58 of the first sidewall 18; a tube 56 positioned within the groove channel 34; and a cover strip 46 attached to the first sidewall 18 and enclosing the access opening 42. The cover strip 46 and the access opening 42 are positioned at the outward surface 58 of the first sidewall 18 at a higher radial location on the first sidewall 18 than the channel 34 location within the first sidewall 18.SELECTED DRAWING: Figure 2A

    【課題】時間経過に伴うタイヤ圧の低下を補償するためにタイヤ空気圧を自動的に維持する空気維持機構をタイヤ内に組み込む。【解決手段】空気維持タイヤ組立体が、タイヤキャビティと第1および第2のサイドウォール18とを有するタイヤと、第1のサイドウォール18内の、細長い流路34と流路34から第1のサイドウォール18の外表面58のアクセス開口部42まで傾斜して延びる細長い溝アクセス通路40とを含む細長い溝32と、溝の流路34内のチューブ56と、第1のサイドウォール18でアクセス開口部42に封入しているカバーストリップ46と、を含む。カバーストリップ46とアクセス開口部42は、第1のサイドウォール18の外表面58の、第1のサイドウォール18内の流路34よりも第1のサイドウォール18の半径方向において高い位置に配置されている。【選択図】図2A
