I have a 986, a 987, and a C 4 and I buy Hankook from Discounttiredirect to run on all of them. They hold wet or dry just as good as any of the others, my tire mounter says they are rounder than most and balance better and they are half the price of michelins. I drive mountain roads every day HARD and I rarely get more than 10K out of any tire on either car. I was a loyal michelin guy for 30 years, but for these cars I think they are over rated and way overpriced. Driving a porsche means buying tires regularly---if you really drive it like the performance car it really is.
