What did these 3 shops have to say about it? Did they see anything of question anything?
I know when I see something that doesn't look right, I will ask the owner about it.
I have a 2009 CC. Between 65 mph and 78mph the ride is rough as hell. Feels like the tires are vibrating. Can't really feel anything in the steering wheel though. Under 65 and over 80 mph seems fine. I've had tires rebalanced 3 times at 3 different places so that's not it. No problems on stock 17s. Do you think I got a bad tire or 2 shipped from tire rack? This sucks. I realize 19s aren't going to be as smooth as the 17s but ive had 20s on another car before. Something is def not right here immediately after the new tire/wheel install. I do have spacers from hr spacers on there as well from ecs. 12mm front, 5 mm back. Tires are 235/35/19s. Any ideas?
