ABSTRACT:
The present invention provides for an improved tire tread having an improved hydroplaning resistance. Specifically, the tread includes one or more tread blocks having one or more walls with an undercut surface to deviate the flow of water from a circumferential groove(s) to a lateral groove(s), thereby providing for improved worn hydroplaning performance of tires.
