Abstract: This disclosure relates to a tire, a rim and a combination thereof that yields improved stability characteristics when the tire is run flat. The combination of this invention yields a structure wherein the tire will operate normally under normal conditions of load and pressure and will operate with the load equally distributed on each sidewall of the tire during run flat operation. In this invention, the tire has an asymmetric sidewall construction resulting from the inclusion of rubber inserts in its sidewalls of different bulk and the rim has axially outward extending rim flange extensions which are angled in relation to the axis of rotation of the rim. The extensions are angled in opposite directions. The proper combination of these features compensates for the camber that the tire is subjected to when it is run flat.

Abstract translation: 本公开涉及一种轮胎，轮辋及其组合，其在轮胎平坦运行时产生改进的稳定性特征。 本发明的组合产生一种结构，其中轮胎将在正常的负载和压力条件下正常运行，并且将在运行平稳操作期间以平均分布在轮胎的每个侧壁上的负载进行操作。 在本发明中，轮胎具有不对称的侧壁结构，这是由于在其不同体积的侧壁中包括橡胶镶嵌件，并且轮缘具有相对于轮辋的旋转轴线成角度的轴向向外延伸的轮缘凸缘延伸部。 延伸部在相反的方向成角度。 这些特征的适当组合补偿轮胎在平稳运行时受到的弯度。
