OMG. I replaced original equipment ContiproContact runflats that were loud and rough. Ok, they were VERY loud and EXTREMELY rough. These are whisper quiet and ride even better than my winter sneakers Michelin Pilot Alpin which are 205/55 16s compared to these 225/45 17s!! The Pirelli Cinturato P7s are amazing! And the same price as Conti Pure Contacts which were being considered for this purchase. I couldn't make them hydroplane, they track true and straight on the 4-lane, they are quiet and smooth and turn-in is quite sharp. You won't regret these.
