The tire includes a pair of sidewalls and a tread, and the tread includes a plurality of tread elements defined by circumferential grooves and lateral grooves. The tread wear indicator is formed in a selected one of the tread elements. The indicator includes a plurality of concentric step elements that descend radially inwardly from a radially outward surface of the selected one of the tread elements. Each step element includes an axially-extending surface that is approximately parallel to and is radially inward of the radially outward surface of the selected one of the tread elements, and a radially-extending surface that extends approximately perpendicular to the axially-extending surface.
