here's a link to a car & driver test on 11 different summer tires. the test consisted of both dry and wet performance and consideration was given to price and treadwear. note that the Eagle F1 GS-D3, ContiSportContact2, and PS2 were ranked 1st, 2nd, and 4th, respectively. the reason the ContiSportContact2 rated higher overall than the PS2 is because of price and treadwear rating, not because of overall performance. but the ContiSportContact2 did outperform the PS2 on the wet surface. one thing to keep in mind is that the tires were not tested in standing water to measure resistance to hydroplaning.
