Abstract
A tire has at least one tread wear indicator. Each wear indicator is a single mark that provides continuous information to the consumer, while changing its presentation based upon the amount of tread wear. The mold blade employed to form the ear indicator has a series of stacked portions, each portion having a different configuration, the configuration being constant for the length of each portion.
