    Abstract: A pneumatic safety tire for motorcycles, which includes a pair of elastic reinforcing layers disposed along the carcass plies of the tire, so as to extend from the proximity of tire beads to tire inner surface under the tread rubber. The Shore A hardness of the reinforcing layer is 45 or more, so that the safety tire can run at a high-speed even after puncture, while providing excellent handling characteristics under normal conditions.

    Abstract: A tire has an asymmetrical carcass comprising two plies of cords forming a network of quadrilateral meshes. The sides of the quadrilaterals form with the circumferential direction of the tire acute angles Alpha and Beta which are different and which vary as a function of the distance of the mesh from the axis of the tire. The angle Alpha is larger than the angle Beta and varies, between any two points located at different distances from the axis, more than does the angle Beta . In manufacturing the tire by turning the edges of the two plies around bead wires on a building drum and then shaping the assembly into the form of a tire, at least one of the bead wires is permitted to rotate about the axis of the tire so that the meshes rotate about normals to the carcass.

    Abstract translation: 轮胎具有包括形成四边形网格网络的两层帘线的不对称胎体。 四边形的侧面与轮胎的圆周方向锐角α和β形成不同，并且其作为网格与轮胎轴线的距离的函数而变化。 角度α大于角度β，并且在距轴线不同距离的任何两个点之间变化，大于角度β。 在制造轮胎时，通过将两层的边缘绕在建造鼓上的胎圈丝上，然后将组件成形为轮胎的形式，允许至少一个胎圈丝围绕轮胎的轴线旋转，使得 网格围绕法向旋转。

    Abstract: A tire construction is disclosed wherein there is a combination of radial and bias plies, there typically being twice as many bias plies as radial plies. In a preferred embodiment for passenger car utilization, three plies are employed, a radial ply being disposed outside two bias plies. Both the bias and radial plies are preferably 12s X 12z twist for 1,260/2 and 840/3 denier cords and 10S X 10Z twist for 1,100/2 and 840/2 denier cords, while either of these twists may be employed with 1,100/3 denier cords. The angle of the bias ply in the cured crown is preferably 35* and the radial ply preferably 90*. The preferred thermal shrinkage at 190* C. of both plies is approximately 17 percent (12 tpi). With these specific parameters, a cooperative structure between the radial and bias plies is effectuated which facilitates manufacture of these tires especially with respect to conventional radial ply tires.

    Abstract: A filament wound aircraft tire of the toroidal type which includes annular fabric strips positioned between the circular piles of the carcass in the heel or rim area, reinforcing the heel and adjacent rim edge increasing the strength and modulus of the tire carcass in this flexure area, and preventing flexure and compression fatigue failures of the carcass piles in these highly stressed areas. This invention constitutes an important improvement on my invention disclosed in my (T. J. Reinhart, Jr.) U.S. Pat. No. 3,171,462 for Toroidal Pneumatic Tire, dated Mar. 2, 1965, and having for an object the provision of means to increase the strength and modulus of the toroidal tire carcass in the area of the reinforcing ring or heel bead, adjacent the outer edges of the split rim or wheel.

    Abstract: A vehicle tire which provides a simple means of mounting, dismounting, or exchanging tire treads. The tire carcass is designed in such a manner that the diameter increases by 15 percent or more when the tire is inflated to operating or operable pressure. On the carcass, in place of the conventional integral tread there is a wide annular groove or channel having spaced sidewalls. The tread comprises an annular nonstretchable flexible band or belt which snugly fits in the channel between the sidewalls. When the tire is inflated and expands radially outwardly, the nonexpandable tread is securely and firmly held in place in the channel, but it can be removed and replaced when the tire is deflated. The interengaging inner annular surface of the tread member or band and the outer surface or bottom of the tread receiving channel may be formed with complemental, interengaging means or lugs which are forced into interengagement with each other when the annular tread band is fitted into the channel and the tire is inflated to resist relative slippage between the tire and the annular belt tread member.
