Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A pneumatic tire structure, comprising: a tread, sidewalls extending from the tread and defining an inner annular opening, an inner annular member, an outer annular member positioned radially outwardly of and symmetrically with the inner annular member, and a plurality of elongated connecting members extending through and within the sidewalls but movable independently thereof to connect the inner annular member to the outer annular member for transfer of forces through tension of the elongated connecting members and, accordingly, between the inner annular member and the outer annular member.
Claim 2
Dependent Claim
88 words
A pneumatic tire structure, comprising: a tread, sidewalls extending from the tread and defining an inner annular opening, an inner annular member, an outer annular member positioned radially outwardly of and symmetrically with the inner annular member, and a plurality of elongated connecting members extending through and within the sidewalls but movable independently thereof to connect the inner annular member to the outer annular member for transfer of forces through tension of the elongated connecting members and, accordingly, between the inner annular member and the outer annular member.
Claim 3
Dependent Claim
17 words
A tire structure as claimed in claim 1 wherein the outer annular member is adjacent the tread.
Claim 4
Dependent Claim
26 words
A tire structure as claimed in claim 2 wherein the outer annular member is in the form of a belt spaced radially inwardly of the tread.
Claim 5
Dependent Claim
17 words
A tire structure as claimed in claim 2 wherein the inner annular member forms the tire bead.
Claim 6
Dependent Claim
26 words
A tire structure as claimed in claim 2 wherein the inner annular member is positioned essentially concentric with but radially outwardly of the inner annular opening.
Claim 7
Independent Claim
157 words
A method of advantageously applying torque to a tire, comprising: applying a relative torque between an inner annular member of a tire and an outer annular member, deforming the tire from a circular configuration by means of a weight force applied to a contact patch between the tire and a supporting surface, transmitting forces between the inner annular member and the outer annular member by means of elongated connecting members extending through the tire sidewalls but movable independent of the tire sidewalls, utilizing the tire deformation to selectively and sequentially tension only elongated connecting members connected to the outer annular member at a point offset from the vertical diameter of the tire, and imparting rotational forces to the tire by means of such offset force and the force imposed through the vertical diameter at the contact area of the tire with the supporting surface, whereby a rotary motion is imparted to the tire by the force couple.
Claim 8
Independent Claim
157 words
A method of advantageously applying torque to a tire, comprising: applying a relative torque between an inner annular member of a tire and an outer annular member, deforming the tire from a circular configuration by means of a weight force applied to a contact patch between the tire and a supporting surface, transmitting forces between the inner annular member and the outer annular member by means of elongated connecting members extending through the tire sidewalls but movable independent of the tire sidewalls, utilizing the tire deformation to selectively and sequentially tension only elongated connecting members connected to the outer annular member at a point offset from the vertical diameter of the tire, and imparting rotational forces to the tire by means of such offset force and the force imposed through the vertical diameter at the contact area of the tire with the supporting surface, whereby a rotary motion is imparted to the tire by the force couple.
Claim 9
Dependent Claim
143 words
In combination with a tire having conventional tread, sidewall and bead, a structure for improved transfer of forces and weight, comprising: an inner annular member secured to the tire, an outer annular member secured to the tire and spaced radially outward from the inner annular member, a plurality of elongated connecting members, each comprising a sleeve and a flexible cord extending freely through the sleeve, secured within the tire sidewalls to permit transfer of forces through the cord, the flexible cords being secured at one end to the inner annular member and at the other end being secured to the outer annular member, whereby, as a result of weight and torque transfer the inner annular member and the outer annular member, forces tending to rotate the tire in a particular advantageous manner on a supporting surface are generated at the outer annular member.
Claim 10
Dependent Claim
143 words
