I have the F1 A/S with 7k and I am getting rid of them. Scalloping, cupping whatever, they are doing it. My Conti's never did this and I am still driving the same way. Had my mechanic and Chrysler check out the car. Everything is fine, it's the tires. They have gotten very noisy also. As one reviewer on the Tire Rack site states, the noise sounds like I have studded tires on. It's really bad at low speeds.

I loved the tires when I first got them. Excellent rain handling, no doubt about it. They were a little rougher riding at first and that smoothed out. Then this started.
I am looking at getting another set of tires. My husband hates the noise of these tires!
