That is good to know! My hydroplaning experience with the Goodyear F1s scared the hell out of me, so I drop down to 60-65 when there is heavy rain. I have run into rain so heavy that I would have had to pull off the road if I was still on the Goodyears. But I had no problems with the P4S. My tread depth is 6/32" so I should be good to go for awhile. AFAIK, only Continental and Michelin have a mileage warranty their summer tires.I am getting some hydroplaning above 90 with the tread at the wear bars
I picking up my second set today!
