    • Disclosed are a run-flat tire and a tire/wheel assembly in which the workability of the tire-to-rim fit has been improved while including a core-type run-flat support member. The tire/wheel assembly is formed by coupling a pneumatic tire and a rim of a wheel. In the tire/wheel assembly, the run-flat support member constituted of a circular shell and elastic rings is inserted into a cavity of the pneumatic tire, in which the circular shell has a support surface thereof extended toward the periphery of the tire and leg portions along each side of the support surface, and the elastic rings support the leg portions of the circular shell on the rim. At the same time, a seat portion and an engaging portion are provided for at least one of the elastic rings, in which the leg portion of the circular shell can be settled on the seat portion, and the engaging portion is extended in an outer tire axial direction from the seat portion and sandwiched between a tire bead base and a rim seat.
    • 本发明公开了一种防漏轮胎和轮胎/车轮组件,其中轮胎到轮辋配合的可加工性已经提高,同时包括铁芯型平板支撑构件。 轮胎/车轮组件通过联接充气轮胎和轮的轮缘而形成。 在轮胎/车轮组件中,由圆形壳体和弹性环构成的行平面支撑构件插入到充气轮胎的空腔中,其中圆形壳体具有朝向轮胎和腿部的周边延伸的支撑表面 沿着支撑表面的每一侧的部分,弹性环支撑轮缘上圆形壳的腿部。 同时,为弹性环中的至少一个提供座部和接合部,其中圆形壳的腿部可以在座部上沉降,并且接合部在外胎中延伸 轴向方向,并且夹在轮胎胎圈基座和轮辋座之间。
