Abstract:
A tread band having a primary groove opening onto a front face of the tread band, a secondary feature molded into the tread band, and a wear indicator molded into a section of an undertread portion of the tread band. The wear indicator is useful for providing an end-of-useable tread indication when the front face of the tread band wears even with a top portion of the wear indicator. Furthermore, the secondary feature may be characterized as opening onto a back face of the tread band, a side face of the tread band or combinations thereof. The section of the undertread portion may extend less than about 4 mm or less than about 3 mm from the back face of the tread band. In other embodiments, the section of the undertread portion may extend less than about 1.5 mm from the back face of the tread band.
