This is my 3rd set of 18 tires on my CTS I was able to get 35K on the OEM Bridgestone Potenzas which I was happy with but I wanted to try the Michelin Pilot Super Sports after reading some possitive reviews. I had them put on at 72K miles on the car right before I took a driving vacation from S. Florida to Western N. Carolina. These tires were awesome on those tight steep mountain roads. Back home here in Florida we have had a very rainy year and it rains very hard here. I do not have to slow down on the expressway during a heavy rain these tires are that good. I now have close to 89K on the car (16K on the tires) and the tread looks like new. I can easily imagine getting 50,000 miles on these tires. I don't think they look as nice as the Potenzas but they certainly make up for that in other areas.
