Just got them fitted on my CM. The drive home felt like I was driving a completely different car. Didn't witness and sudden steering jolts like I would with the old run flats. Nice and smooth. Drove through a monsoon on the way home and didnt notice any hydroplaning.

 

I had Michelin Defenders in the same size put on our car last week. As expected, the handling is not quite as sharp as it was with the Bridgestone run flats, but I would bet an average driver would not even notice that. The ride is now far more comfortable. Anyone want to buy a used set of 18 inch Bridgestone run flats with lots of tread left?
