Not happy with mine, regarding road noise. By now I have around 16k on it after 5 month of ownership and lately drive train noises are getting apparent.
I have a GT2 with the Michelin 4s'.
Maybe it's because the 'honeymoon' is over and I'm starting to find small flaws in this 'relationship'? The noise sounds like drive line component bearings are having issues.
There is a very audible humming noise with a destinct 'per revolution' characteristic going on between 30 and 65 mph which I can coax away briefly by very slight steering manouvers and changing the loading of components in the suspension and drivetrain slightly. I don't think it's tire noise (though they are getting near the wear marks) as it sound far more mechanical than that.
I'll report it to my dealer today while at service and will re-evaluate things when I get new tires at my next oil change.
