Abstract
A tire structure which augments a conventional tire structure by including therein a load transferring configuration in each sidewall from the bead to the tread. The beads of each sidewall are contacted tangentially by a plurality of elongated connecting members and the sidewall area between the bead and the connecting members is reinforced.
Claims17
A pneumatic tire structure comprising:
- a tread;
- a pair of opposing sidewalls extending from said tread and defining an inner annular opening;
- an inner annular member carried by each sidewall;
- from three to eight elongated wire or cord members arranged symmetrically around and tangential to each said inner annular member;
- and
- mesh material reinforcing in said sidewall only in the area between each point of tangency, the inner annular member and the adjacent elongated wire or cord member.

A pneumatic tire structure comprising:
- a tread;
- a pair of opposing sidewalls extending from said tread and defining an inner annular opening;
- an inner annular member carried by each sidewall;
- from three to eight elongated wire or cord members arranged symmetrically around and tangential to each said inner annular member;
- and
- reinforcing comprising a built-up area of additional rubber on said sidewall limited to and completely filling the area between each point of tangency, the inner annular member and the adjacent elongated wire or cord member.

A pneumatic tire structure comprising:
- a tread;
- a pair of opposing sidewalls extending from said tread and defining an inner annular opening;
- an inner annular member carried by each sidewall;
- from three to eight elongated wire or cord members arranged symmetrically around and tangential to each said inner annular member;
- and
- reinforcing comprising an integral sidewall rubber composition of higher durometer than the surrounding sidewall rubber, said reinforcing being limited to and completely filling the triangular area between each point of tangency, the inner annular member and the adjacent elongated connecting member.

A pneumatic tire structure comprising:
- a tread;
- a pair of opposing sidewalls extending from said tread and defining an inner annular opening;
- an inner annular member carried by each sidewall;
- three elongated wire or cord members arranged symmetrically around and tangential to each said inner annular member;
- and
- reinforcing in said sidewall only in the area between each point of tangency, the inner annular member and the adjacent elongated connecting member, and lines normal to each elongated member and tangent to said inner annular member.

A pneumatic tire structure comprising:
- a tread;
- a pair of opposing sidewalls extending from said tread and defining an inner annular opening;
- an inner annular member carried by each sidewall;
- from three to eight elongated wire or cord members external to said sidewalls, and arranged symmetrically around and tangential to each said inner annular member;
- and
- reinforcing in said sidewall only in the area between each point of tangency, the inner annular member and the adjacent elongated connecting member.
3 more elements
A method of adapting a cured tire for improved transmission of torque comprising:
- affixing from three to eight wire reinforced rubber tapes symmetrically around and tangential to the annular bead of each sidewall of said tire, and reinforcing each sidewall between each point of tangency and the adjacent reinforced tape by application of unvulcanized rubber and curing the unvulcanized rubber and the tapes to bond the reinforcing and the tapes to each sidewall.
