Abstract: An inner tire used in a dual-chambered tire is provided by an inner tire in which an exterior sidewall of tire provides for two annular rows of overlapping raised facets that extend above the exterior surface of the tire. Each facet defines a right angle with respect to the adjacent sidewall of the tire and provides for an elevated surface having a substantially uniform height with respect to the underlying tire exterior surface. The facets further define a plurality of gaps and passageways that have a constant height and through which pressurized air may flow during the inflation of the outer tire. The air gaps and air passageways defined by the facets have a sufficient depth that the resulting passageways do not collapse when the pressurized inner tire is in engagement with the pressurized outer tire.

Abstract translation: 用于双室轮胎的内轮胎由内轮胎提供，其中轮胎的外侧壁提供在轮胎的外表面上方延伸的两个重叠的凸起面的两个环形排。 每个小面相对于轮胎的相邻侧壁限定一个直角，并提供相对于下面的轮胎外表面具有基本均匀高度的升高表面。 小平面还限定了多个间隙和通道，其具有恒定的高度，并且加压空气在外轮胎的充气期间可以通过该间隙和通道流动。 由小面限定的空气间隙和空气通道具有足够的深度，使得当加压的内胎与加压外轮胎接合时，所得到的通道不会折叠。
