摘要： A tread wear indicator for a tire is provided. 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 adjacent a selected one of the circumferential grooves. The indicator includes a plurality of step elements descending from a radially outward surface of the selected one of the tread elements toward the base of the selected one of the circumferential grooves. 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. The axially-extending surface of each step element is formed with indicia visible to a user of the tire.
