An improved tire structure and method in which, supplementary to the conventional tire structure, a programmed load-transferring configuration is provided at each tire sidewall from an inner annular member, preferably the bead area, to an outer annular member, preferably the tread area. The two annular members are interconnected by elongated connecting members which join the inner annular member to the outer annular member essentially independently of the conventional tire structure. Preferably, the structure is provided with an apex of two connecting members at each connection to the outer annular member to provide improved torque application in both directions. |

DETAILED DESCRIPTION The instant invention includes, in addition to the conventional structure of a tire, be it bias ply, bias belted or radial, a network of elongated connecting members of cords or wires which programmably transmit weight forces and torque forces substantially independently of the remainder of the tire carcass.
Basically, the networks exist between an annular member towards the inner surface of the tire, preferably in the bead area, and an outer annular member preferably in the tread area.
The elongated connecting members run through both sidewalls of the tire but are free to move independent of the sidewalls.
Preferably, the elongated connecting members are incorporated internally in the tire carcass, though an external network would also function.
As a result of the characteristic of the elongated connecting members of not transmitting forces in compression but only in tension, and as a result of the deformation of the tire at the contact patch of the tire with a surface, only the elongated connecting members in the upper portion of the tire support substantial portions of the weight imposed upon the tire.
In a fashion, the bead area can be thought of as being suspended from the upper portion of the tread area.
This is possible because of the prestressing of the conventional sidewall as a result of the inflation gas which maintains the tread area away from the bead area.
The support of the bead area by the tread area is, in a static condition, usually symmetrical.
However, when a torque is applied between the bead area and the tread area, as in the instance when the tire is driving or braking a vehicle, the elongated connecting members transmit the torque in a selective programmed manner.
This permits the bead, when power is applied to the wheel through an axle, to pull on the tread at positions offset from the vertical diameter of the wheel.
By thus pulling on the tread, force is transferred and applied to the tread offset from the vertical diameter of the wheel in an upper quadrant of the wheel
