Coming from an E90 with michelin rft i can tell you they provided a hard drive and were prone to break after an apparent harmless pothole. I learned the hard way since during 5 year ownership I had 3 broken. Now this new generation in my F30 are so much better,that I only hope they can withstand potholes better. I am very happy so far with the potenzas and the current sport suspension is GREAT.
