Abstract:
A tire containing a reinforcement ply in a ground-contacting tread region of the tire in the form of a hoop or band, the reinforcement ply comprising a plurality of continuous helical windings across the axial width of the ply of at least one reinforcing member, each reinforcing member comprising at least one filament, the helical windings being substantially parallel to the circumferential direction of the tire and laid at a substantially constant end count perpendicular to their longitudinal direction, wherein the extensibility of the at least one reinforcing member in the longitudinal direction thereof increases continuously across the axial width of the ply from the axially outer edges to the axial center of the ply by displacement of the at least one filament in each reinforcing member perpendicularly or laterally from the longitudinal centerline (CCL) of the reinforcing member.
