I recently replaced the OEM Yokohama's with Michelin Pilot Sport Ribs. The Michelin's are much quieter. I think it's a much nicer experience. They also grip extremely well in the wet. On the downside-my gas mileage dropped a bit, about .5 to 1 MPG (depending on the weather). Price wise they seemed to be just about the same as the Yokohama's.
