Tire with tread including rib having chamfered surface

摘要

This application discloses a tire comprising a circumferential tread including at least one tread element having a top surface, at least one edge, and at least one chamfered surface extending between the top surface and the edge. The chamfered surface is oriented at an angle relative to the top surface of the tread element that varies along the length of the chamfered surface. Alternatively, the chamfered surface may have a width and a height that vary along their respective lengths.
