I wrote Michelin in dec 2011 asking them to come out with a tire to fit my 135i sine none were available. They answered with the Super sports! I have always been a Michelin fan, and these tires make me even more of one. First they are comfortable about absorbing bumps and anomalies in the road but the steering response and accurate handling would lend you to believe they would be teeth chattering. Second the braking is much better! I noticed the responsiveness as soon as I left the tire shop. These tires are expensive, nearly the cost of the run flats but I would buy them again considering they actually have a tread wear warranty it's a no brainer. Good job Michelin. Great tire!
