Abstract
Abstract Disclosed is a radial ply tire with a circumferentially located cincture assembly composed of endless plies in which the cords of the plies are disposed at atypical, large angles relative to the crown of the tire. The cords are held within an elastomeric matrix filled with small, oriented fibers. The plies have the same stabilizing effect as do conventional ''''low angle'''' breakers; but, because of their relatively large cord angles, are more extensible. As a result, radial ply tires featuring these high angle breakers may be manufactured by conventional ''''hard drum'''' or ''''flat band'''' processes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A radial ply tire built and cured by conventional techniques used to build and cure bias ply tires wherein said radial ply tire comprises a circumferentially disposed breaker assembly between the carcass and tread portion of the tire, said assembly consisting of a plurality of endless breakers, each of said breakers comprising an elastomeric matrix containing: a. spaced, mutually parallel, continuous lenGths of cord disposed at a large angle relative to the plane containing the circumferential centerline of the tire; 1. said large angle being of a preselected magnitude no less than 25* and no greater than 65*; and b. uniformly dispersed, discrete filaments oriented in a predetermined direction relative to the disposition of said lengths of cord.
Claim 2
Dependent Claim
118 words
A radial ply tire built and cured by conventional techniques used to build and cure bias ply tires wherein said radial ply tire comprises a circumferentially disposed breaker assembly between the carcass and tread portion of the tire, said assembly consisting of a plurality of endless breakers, each of said breakers comprising an elastomeric matrix containing: a. spaced, mutually parallel, continuous lenGths of cord disposed at a large angle relative to the plane containing the circumferential centerline of the tire; 1. said large angle being of a preselected magnitude no less than 25* and no greater than 65*; and b. uniformly dispersed, discrete filaments oriented in a predetermined direction relative to the disposition of said lengths of cord.
Claim 3
Dependent Claim
27 words
The radial ply tire as defined in claim 1, wherein said filaments are oriented in a direction substantially parallel to the disposition of said lengths of cord.
