Abstract: A method for detecting ply wire anomalies in a tire carcass ply having a plurality of spaced apart ply wires extending across a tire carcass, the method comprising the steps: constructing a green tire carcass in a diametrically expanded toroidal configuration, the carcass comprising a pair of beads, the carcass ply extending from bead to bead, at least one crown layer covering the carcass ply and having a peripheral skirt region; and sidewalls covering the carcass ply and extending from the beads to the crown layer and having edge portions intersecting the crown layer; mounting a wire sensor apparatus proximal to the tire carcass ply, the wire sensor apparatus including a wire sensor for detecting the presence of a proximal ply wire; establishing relative movement between the wire sensor and the tire carcass whereby the plurality of spaced apart ply wires are sequentially placed into proximal relationship with the wire sensor; and generating sequential data from the wire sensor indicative of at least one ply
