I definitely recommend the Hankooks. Ran a escort for a WTC Steel delivery last week and the tires really proved themselves. They have always been good on the WV twisties but hadn't done much rain. On the esort run I had 2.5hrs highway driving in SEVERE rain, some so hard I could barely see, and I had NO issues with hydroplaining.
I can not remember hitting and standing water in the road but I will agree with that statement Aobfarm.. 80+ down the highway in a heavy downpour and no issues at all. I might have a T-shirt made, I survived a downpour in the Slingshot! lol
