Just purchased these tires to replace terribly hard and jarring OEM Dunlap run-flats. I have had them only a few days and will post again when I have 5k or 10k miles on them. So far, they have exceeded my expectations. They are quiet and smooth, but don't lose the road feel and responsiveness that I expect from my JCW Mini Copper S. They also really change the stance of the car and look incredible...they have an aggressive tread pattern which gives the car a great look when parked. Additionally, I must offer positive comments about the service at Tire Rack's South Bend operation. I live in the Chicago area so I drove my car over while on business. Kaitlin, a member of their sales staff greeted me at the counter, and assisted me all they way through my order and installation process. Another sales person, Keith, helped me purchase a dented/scratched aluminum wheel for a spare tire that they created out the best remaining run-flat...he found a great wheel and discounted it heavily so I ended up with a much better solution than purchasing a donut spare from MINI for $300. Oh, and while I waited, they served FRESH coffee and tea and hot chocolate, with 5 or 6 different creamer options. They have thought of everything...overall, a very satisfying experience. I wish that all consumer related companies cared as much about their customers as the great people at Tire Rack do!
