    摘要： A directional high performance pneumatic tire having improved wet traction has an annular aqua channel and lateral grooves which direct water from the footprint to the shoulder area of the tire to help prevent hydroplaning. The aqua channel has an extended U-shape wherein one wall of the aqua channel has a steeper incline than the other side of the aqua channel. At least one side of each aqua channel is defined by lugs of various lengths, and longer lugs of the lugs of various lengths extend into the aqua channels and have an inclined wall. The varying length of the lugs cause the aqua channel to vary in width, and the aqua channel, in the narrower portion varies in width from 7-12% of the tread width, and in the wider portion varies in width from 17% to 22% of the tread width. In a preferred embodiment, the aqua channel may have a step between its shoulder side and its center side wherein the shoulder side is higher by a distance d. In one illustrated embodiment, a center tread portion of the tire, bounded by an aqua channel and a center groove, and two lateral grooves, comprises a single block element.

    摘要： An asymmetric non-directional tread 12 for a tire 10 is disclosed. The tread 12 has a plurality of ground engaging tread elements 22 separated by circumferential and lateral grooves 24,28. The net contact area in a first tread half 30 is approximately equivalent to a net contact area in a second tread half 32 although the tread stiffness in the first tread half 30 preferably is higher than in the second tread half 32. The outboard side of some circumferential grooves 24 may be tapered to buttress tread elements 22 against cornering forces.
