Abstract
Abstract Belted pneumatic tires, each belt ply of which includes both metallic and non-metallic cords interspersed with one another and of which the non-metallic cords are made of a material having a relatively high modulus generally of the same order of magnitude as that of the metal, are disclosed. In a preferred arrangement, each belt ply has steel wire cords arranged in a 1:1 alternating sequence with glass fiber cords. The sequence can be varied by having successive metal wire cords separated by two or more non-metallic cords, or by having successive pairs or greater numbers of metal cords separated by one, two or more non-metallic cords, and so forth. The use in tires of belts of such cords, eliminates tire wear and failure due to buckling and birdcaging of belts formed solely from non-metallic tire cords. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A belted tire comprising a toroidal carcass terminating at its radially inward-most edges in a pair of beads, a tread surrounding the region of said carcass, sidewalls outlying the lateral regions of said carcass from said beads to the marginal regions of said treads, and a tread-reinforcing belt structure disposed circumferentially of the crown region of said carcass beneath said tread, said belt structure including at least one ply of a plurality of first continuous filament tire cords in which the filamentary elements are exclusively of metal wire and a plurality of second continuous filament tire cords in which the filamentary elements are exclusively of a high modulus non-metallic synthetic fiber, each ply of said belt structure having all said cords extending in the same direction in closely spaced, non-intertwined, side by side, relation and being interspersed with one another in such a fashion that at least some of said first cords have disposed therebetween at least one of said second cords.
Claim 2
Dependent Claim
162 words
A belted tire comprising a toroidal carcass terminating at its radially inward-most edges in a pair of beads, a tread surrounding the region of said carcass, sidewalls outlying the lateral regions of said carcass from said beads to the marginal regions of said treads, and a tread-reinforcing belt structure disposed circumferentially of the crown region of said carcass beneath said tread, said belt structure including at least one ply of a plurality of first continuous filament tire cords in which the filamentary elements are exclusively of metal wire and a plurality of second continuous filament tire cords in which the filamentary elements are exclusively of a high modulus non-metallic synthetic fiber, each ply of said belt structure having all said cords extending in the same direction in closely spaced, non-intertwined, side by side, relation and being interspersed with one another in such a fashion that at least some of said first cords have disposed therebetween at least one of said second cords.
Claim 3
Dependent Claim
47 words
A belted tire as claimed in claim 1, wherein the material of which said component filamentary elements of said metal wire tire cords are made is steel, and the material of which said component filamentary elements of said non-metallic fiber tire cords are made in glass fiber.
Claim 4
Dependent Claim
46 words
A belted tire as claimed in claim 1, wherein the material of which said component filamentary elements of said metal wire tire cords are made is steel, and the material of which said component filamentary elements of said non-metallic fiber tire cords are made is "Kevlar."
Claim 5
Dependent Claim
24 words
A belted tire as claimed in claim 1, wherein the metallic to non-metallic cord sequence in each ply of said belt structure is 1:1.
Claim 6
Dependent Claim
24 words
A belted tire as claimed in claim 1, wherein the metallic to non-metallic cord sequence in each ply of said belt structure is 1:2.
Claim 7
Dependent Claim
24 words
A belted tire as claimed in claim 1, wherein the metallic to non-metallic cord sequence in each ply of said belt structure is 1:3.
Claim 8
Dependent Claim
24 words
A belted tire as claimed in claim 1 wherein the metallic to non-metallic cord sequence in each ply of said belt structure is 2:2.
