Summary:A method of installing a tread wear sensor in a tire includes configuring multiple tread wear indicators to each include a stack of sacrificial resistive sensor elements. The stacks of resistive sensor elements are affixed to respective selected tread lugs positioned at dispersed axial locations across a tire tread region. The resistive sensor elements sacrificially abrade and a change in resistance in each stack is measured. Connector assemblies within the tire carcass cavity are positioned radially opposite the selected tread lugs. A needle projection from each of the connector assemblies is inserted radially outward through the tire carrying leads which engage and establish electrical contact with a respective stack of resistive sensor elements.
