I had read other reviews that indicated tire noise could be a problem, especially with the Pirelli P6 tires. I thought I had escaped that fate as the first year was great; lot's of fun to drive, average 32.5 mpg overall, reasonably peppy and good brakes and handling. After the 16,000 miles service and tire rotation the tire howl began. I returned to Audi service who tell me that alignment and suspension are in spec and the tires are cupped which is causing the road noise. The noise has only gotten worse. Plenty of tread left but unless the Pirelli tire dealer I see Saturday does something to adjust this, I will have to report to Audi and Pirelli that they have lost a customer for life.
