1. A vehicle tire and tread wear device assembly comprising:

  • a tire having a radially outward plurality of tread elements;

    at least one tread element projecting from the base of the tread and having a defined tread depth;

    a tread wear indicator comprising at least one sacrificial resistive sensor element affixed to the one tread element, the one sensor element operative to progressively change in resistivity responsive to progressive tread wear on the one tread element;

    electrical resistivity measuring means connected to the one sensor element for generating data indicative of a measured change in resistivity in the one sensor element;

    data processing means for determining a tread wear status of the one tread element based on the measured change in resistivity of the one sensor element.
