摘要： A radial-ply pneumatic tire carcass has a reverse curvature, an outwardly concave shape, centered about the tire's equatorial plane. A wedge of elastomeric material is positioned above or below the belt structure of the tire. If positioned above the belt structure, the wedge is used with a carcass cord angle in the range from 65.degree. to 80.degree.. This carcass structure also may be used when the wedge is positioned between the belt structure and carcass. The tire has an aspect ratio less than 75%, but 40% to 65% is preferred. The wedge has a shape on its radially inner side that is similar to a low amplitude cosine function. Particularly when the wedge is above the belt structure (providing both it and the belt structure with a reverse curvature), the belt cord angle is less than a "critical angle" of about 25.degree.. The invention can provide a radial-ply belted tire which has "natural shape" in the portion of the radial carcass underlying the belt structure, but the "natural shape" is for those low cord angles used in the belt structure.
摘要翻译： 径向帘布层充气轮胎胎体具有以轮胎的赤道平面为中心的反向曲率，向外凹的形状。 弹性体材料的楔子位于轮胎的带结构的上方或下方。 如果位于皮带结构之上，楔子的使用范围为65°至80°。 当楔形物定位在带状结构和胎体之间时，也可以使用该胎体结构。 轮胎的纵横比小于75％，优选为40％至65％。 楔形物在其径向内侧具有类似于低幅度余弦函数的形状。 特别是当楔形件位于带状结构之上（提供带状结构和带状结构的反向曲率）时，皮带绳角度小于约25°的“临界角”。 本发明可以提供一种在带状结构下方的径向胎体部分具有“天然形状”的径向带状轮胎，但是“自然形状”是用于带结构中使用的那些低帘线角。

摘要： This specification discloses a run flat insert for use with a tire and rim assembly. The insert comprises an annular band having radially inner and outer surfaces and a plurality of circumferentially spaced supporting legs extending toward the axis of rotation of the tire from the radially inner surface of the annular band. Preferably, the supporting legs are inclined with respect to the axis of rotation of the insert; half are inclined in one direction away from the mid-circumferential plane and the other half are inclined in the opposite direction away from such plane.The circumferential spacing between each supporting leg and the next circumferentially adjacent supporting leg inclined in the same axial direction is at least thirty percent of the circumferential width of the supporting legs at the radially inner ends.

摘要： An integral tire wheel structure (10) comprising an annular generally C-shaped support member (12) having disposed at its radially outer end a ground-engaging tread portion (14), an annular generally C-shaped decoupling member (16) disposed at the radially inner end of the annular support member, and an annular mounting member (18) disposed at the radially inner end of the stress decoupling member. The integral tire wheel being made of material wherein the modulus of elasticity divided by the ultimate strength to the three halfs power is no greater than about 2.6.
