Abstract: A pneumatic tire has a tread with plurality of grooves creating tread elements therein and defining a non-skid tread depth measured from the radially outer surface of the tread to the radially innermost surface of the grooves. Groove voids are located radially inward of the tread surface. The groove voids do not extend to the unworn tread surface and have a primary axis of orientation along the circumferential length of the tread. The primary axis of orientation of the groove voids is 0°-35° relative to the equatorial plane of the tire. The groove voids are aligned such that, when the tire tread is worn to a depth wherein the groove voids are exposed, a groove is created in the tread. The created groove extends in the circumferential direction and has a circumferential length greater than the length between the leading and trailing edges of the tread footprint.

Abstract translation: 充气轮胎具有胎面，其具有多个槽，在其中形成胎面元件，并且限定从胎面的径向外表面到槽的径向最内表面测量的防滑胎面深度。 沟槽空隙位于胎面表面的径向内侧。 凹槽空隙不延伸到未磨损的胎面表面，并具有沿着胎面的周向长度的主轴线。 槽空隙的主轴取向相对于轮胎的赤道面为0°-35°。 凹槽空间对准，使得当轮胎胎面磨损到其中凹槽空隙暴露的深度时，在胎面中产生凹槽。 所产生的凹槽在圆周方向上延伸并且具有大于胎面足迹的前缘和后缘之间的长度的圆周长度。
