A tire including a tread wear indicator is provided. A first cutout is formed in a wall of a first selected tread element and faces a selected segment of a circumferential groove. A second cutout is formed in a wall of a second selected tread element and is opposite the first cutout. An indicator is formed in and extends across the selected circumferential groove segment and the first and second cutouts. The indicator includes a plurality of step elements descending from a radially outward surface of the tread toward the bottom of the groove segment. Each step element includes an axially-extending surface approximately parallel to and radially inward of the radially outward surface of the tread, and a radially-extending surface approximately perpendicular to the axially-extending surface. The axially-extending surface of each step element is formed with indicia that are visible before tire wear commences.
