Abstract
A tire includes a circumferential tread extending in a circumferential direction circumscribing an axis of rotation. The circumferential tread includes a transverse groove having a plurality of protrusions protruding from a bottom portion of the transverse groove. One or more of a depth, a width, and a length of the transverse groove decreases in a direction parallel to the axis of rotation. The plurality of protrusions are circumferentially spaced apart across the bottom portion of the transverse groove.
