Abstract
A tread wear indicator is affixed to a respective tire tread element. The indicator is constructed as a plurality of radially stacked sensor elements operatively configured and located to sequentially sacrificially abrade and change in electrical resistance responsive to a progressive tread wear of the respective tread element. The sensor elements are connected by circuitry that communicates a data signal from the sensor elements to a data processor indicative of a change in cumulative resistivity of the sensor elements. The data processor receives the data signal from the sensor elements and determines a radial wear level of the tread element based on the data signal. Multiple tread wear indicators may be mounted to respective tread lugs across the tread to derive a tread wear status based upon the tread wear profiles of the respective lugs.
