Abstract
A directional pneumatic tire having improved wet traction is provided. The tread is divided into two annular portions, each annular portion comprising a plurality of block elements separated by lateral grooves. The block elements extend continuously from a shoulder area of the tire to a mid portion of the tread. The block elements have substantially circumferentially aligned notches in leading and trailing groove walls, wherein each notch is defined laterally by a narrow bridge of rubber. The tread has curved lateral grooves to direct water from the footprint to the shoulder area of the tire to help prevent hydroplaning. The pitch boundaries between annular portions of block elements may be skewed. The curved lateral grooves and the skewing reduce noise properties of the tire.
