Abstract
The present invention includes a tire tread for a tire having laterally and circumferentially extending grooves that define tread blocks. The tread includes one or more split bridges extending within one groove of said grooves and extending from one of a pair of opposing sides. Each of the one or more split bridges has a length spanning the groove width except for a narrow gap, the length being formed by one or more projections extending from one of the opposing sides and towards the other of the opposing sides. One projection of the one or more projections extends from one side of the opposing sides of the one groove, where each of the one or more split bridges is spaced a predetermined distance from a bottom surface of the groove to provide a void between the split bridge and the bottom surface.
