It isn't the water spots that bother me. I was driving home from an open track day at Pocono Raceway and got caught in a heavy thunderstorm. Water was everywhere. Used a spare pair t-shirt (or maybe it was underwear
) to help dry the back of the windshield. The lack of traction is what nearly killed me. I have Firestone Firehawk SZ 50EP on my car, 275/40/17 in the back. When it first started, and the rain was light, I could roll along at a slow speed and be alright. But when it started to pour, I literally slowed down to about 30mph (on the highway where the speed limit is 65) and I was still hydroplaning. Scared the living crap out of me. Next time, I'm just finding the nearest underpass or wide shoulder and stopping...
