Abstract: A first tread pattern display system for new tread patterns includes a first upper sidewall part, a second upper sidewall part, a first tread shoulder part, a second tread shoulder part, and a middle tread part. The first upper sidewall part removably attaches to the first tread shoulder part by a plurality of projections extending from the first upper sidewall part to corresponding recesses in the first tread shoulder part.

Abstract: 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 circumferential grooves and a plurality of lateral grooves. The tread wear indicator is formed in a selected one of the lateral grooves adjacent a selected one of the circumferential grooves. The indicator includes a plurality of step elements descending from a radially outward surface of the tread toward the base of the selected one of the lateral 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.
