I found them very noisy on the front at motorway speeds. Wet weather was 'ok'. Car at times 'tramlined' when doing slight steering adjustments at medium speeds (I understand that this is a run flat trait).
I lived, ultimately in denial, that they were ok for about 5000Km's until finding a set of 4 Conti Sport 2's on sale. The Conti's make the car feel how it should. Nice and quiet, and nice handling too.
Not going back to Potenza run flats. Have had Potenza non-runflats on another car (Volvo V50) & they were ok...
