A tread wear indicator is affixed to a respective tire tread element. The indicator is constructed as a plurality of electroactive sensor elements operatively configured and located to sequentially sacrificially abrade and change in electrical signal responsive to a progressive tread wear of the respective tread element. The electroactive elements are connected by printed circuitry that communicates an electrical signal to a passive RFID sensor tag that can be powered and read by a RFID reader.
