Abstract
Abstract A tire of vulcanized elastomer having at least two carcass plies having reinforcing cords embedded therein with the cords in each ply extending continuously at a bias angle from one bead to the opposite bead of the tire. An overhead ply having metal reinforcing wires therein is provided over the carcass ply, with the wires in the overhead ply spliced in the crown region of the tire and extending at equal but opposite bias angles on axially opposite sides of the tire through the sidewalls and terminating adjacent the beads.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A pneumatic tire having a carcass of textile cord reinforced elastomer and a pair of sidewalls terminating in axially spaced beads with the crown region thereof surmounted by a tread of elastomeric material, the said tire comprising: a. at least two plies of said cord reinforced elastomer disposed in annularly superposed arrangement with the cords in each ply interconnecting the beads and extending through the crown region at an acute angle to the plane of rotation; and, b. at least one overhead ply of elastomer annularly superposed over said carcass plies having wire reinforcing cords therein, the said wire cords extending through the sidewalls of the tire and terminating axially closely adjacent the beads and radially outwardly therefrom with the said wire cords in each overhead ply on opposite sides of the axial midplane making equal but opposite acute angles therewith and each of said wire cords is discontinous at the axial midplane of the tire.
Claim 2
Dependent Claim
156 words
A pneumatic tire having a carcass of textile cord reinforced elastomer and a pair of sidewalls terminating in axially spaced beads with the crown region thereof surmounted by a tread of elastomeric material, the said tire comprising: a. at least two plies of said cord reinforced elastomer disposed in annularly superposed arrangement with the cords in each ply interconnecting the beads and extending through the crown region at an acute angle to the plane of rotation; and, b. at least one overhead ply of elastomer annularly superposed over said carcass plies having wire reinforcing cords therein, the said wire cords extending through the sidewalls of the tire and terminating axially closely adjacent the beads and radially outwardly therefrom with the said wire cords in each overhead ply on opposite sides of the axial midplane making equal but opposite acute angles therewith and each of said wire cords is discontinous at the axial midplane of the tire.
Claim 3
Dependent Claim
21 words
The tire defined in claim 1, wherein the said wire cords are formed of a plurality of metal filaments twisted together.
Claim 4
Dependent Claim
39 words
The tire defined in claim 2, wherein each of said cords has a diameter in the range 0.020 - 0.100 inches and said cords are spaced so as to provide 8 - 35 cords per inch of ply material.
Claim 5
Dependent Claim
27 words
The tire defined in claim 1, wherein the said wire cords are aligned to within -5* to +10* of parallel with the cords in alternate carcass plies.
Claim 6
Dependent Claim
21 words
The tire defined in claim 1, wherein the said wire cords extend to within 1 - 5 inches of the beads.
Claim 7
Dependent Claim
31 words
The tire defined in claim 1 having a lug tread with the cords in said overhead ply making an angle of within 15* of perpendicularity with the length of said lugs.
