    Abstract: A tire tread has at least one cavern formed in the sidewall of the traction elements of the tire. The cavern has a base with information therein to indicate the state of wear of the tire and a ceiling that is progressively worn away as the tread wears. Multiple caverns may be formed in the traction elements. If arranged in a series at progressively increasing or decreasing radial heights, the remaining tread life is communicated to an operator. If the caverns are located in different locations of the tread, relative wear patterns of the tire can also be indicated.

    Abstract translation: 轮胎胎面具有形成在轮胎的牵引元件的侧壁中的至少一个洞穴。 洞穴有一个底部,其中有信息表示轮胎的磨损状态,以及当胎面磨损时逐渐磨损的天花板。 可以在牵引元件中形成多个洞穴。 如果以逐渐增加或减小的径向高度串联布置,则将剩余的胎面寿命传达给操作者。 如果洞穴位于胎面的不同位置,则也可以指示轮胎的相对磨损图案。
