A tire with tread (20) including a plurality of grooves (24) comprising groove segments (28A) and a tread wear indicator (50) is disclosed. The tread wear indicator (50) is formed in a selected one of the groove segments (28A) and extends completely across the width of the selected groove segment (28A). The tread wear indicator (50) includes a plurality of step elements (52, 54, 56, 58) descending from a radially outward surface of the tread (20) or the tread wear indicator (50) toward the bottom of the selected groove segment (28A), wherein each step element (52, 54, 56, 58) includes a first surface (52A, 54A, 56A, 58A) being at least approximately parallel to the radially outermost surface of the tread (20), and a radially-extending second surface (52B, 54B, 56B, 58B) extending at least approximately perpendicular to the first surface (52A, 54A, 56A, 58A). The first surface (52A, 54A, 56A, 58A) of each step element (52, 54, 56, 58) is formed with or comprises indicia (60). All of said indicia (60) are visible to a user of the tire (10) from a radially outward direction when the tire is unworn.
