The Bridgestone run-flats are a definite fault for my 2007 328i sedan - - noisy, premature wear at 15K miles, overall poor performance. BMW should make buyers aware of the "replacement before $20,000 half-price discount" (why so secretive????); but even more so should get rid of them altogether. Very poor choice for a luxury sedan. BMW should listen to their consumers and ditch the RFTs. This is my third 3 series though the first with RFTs, but will be my last if BMW sticks with the run-flats. Other than this one complaint, I love the car. Considering putting regular radials on it and putting a compact spare/jack in the trunk!
