摘要：
A tire having a tread with a novel groove structure for enhanced wet and snow traction is provided. The groove includes an upper portion and a lower portion that can provide enhanced wet and snow traction over various stages of tread wear without unnecessary compromise to the tread rigidity. The lower portion includes one more voids for the accumulation and/or evacuation of fluids.
