I just replaced four of these on my ‘06 Cayenne S at just over 65K and, even then, only because of a fatal breach that could not be repaired and required replacement of all four. My shop tried to talk me into Yokohama (Yomama’s) but I insisted on these. Interestingly, they came in at a lower price than the Yokohama’s. These Ziex’s have saved my life on more than one occasion due to the exceptional performance of both car and driver. ;-}. The handling is PHENOMENAL. Most Porsche drivers choose their cars precisely for the performance and handling. I am no acceptation. My daily drive is a winding two lane mountain road in New Mexico with ALL weather conditions. As far as snow is concerned, they do pack up and can be a bit of a challenge at speed. But one should not be hauling ass in a Porsche or any vehicle in snowy conditions anyway. Remember 2nd gear is your friend in snow. In every other way... I LOVE THESE TIRES and HIGHLY RECOMMEND THEM for those who love performance driving but hate parting with the BIG BUCKS.
