The PS2s and ContiSportContact 2 are asymmetric tires but neither has directional tread. A directional tread design would be expected to provide the best resistance against hydroplaning. From my limited rain experience, the PS2s do very well but I have not driven at speed through any pooling water. The water-channeling directional tread design of the Goodyear Eagle F1 GS-D3 is the tire you want to get if rain and/or standing water is something you experience frequently. It incorporates long channels in the tread design to remove water and keep the tread in contact with the road.
