ABSTRACT:
A tire for use on a vehicle capable of spinning the tire relative to the ground surface that the vehicle is operable upon. The tire includes a plurality of ground engagable tread elements. Each of said tread elements at least partially defines a transversely extending groove. The improvement comprises a relief located at the intersection of the groove and the ground engaging portion of the tread element. The relief reduces the propensity of chunking of a leading edge of the tread element during operation of the tire.
