Had these OE tires rotated on my new '13 VV CC at the first service interval at 10,000 miles Tires rotated front to back and they started making noise. Thought maybe they would settle in after a bit. Switched to my dedicated snow set up for the winter about a month after having them rotated and forgot about it during the long winter we had in NE Ohio. Just switched them back last month as spring is here and temps are up and whomp whomp whop, most terrible at 25-30 mph. Rotated back to front and it was worse. Car has 17,500 miles on it and two winters I ran the dedicated snow set up. So the tires maybe have 10K on them?? VW and Conti would not provide any warranty or good faith credit but dealership is helping me out on the mount and balance of new set. The ruling was that it is not the fault of the car or the tire but a combination of both because of the sport suspension. With a treadwear of 500 I would think 30K miles would be reasonable with my spirited driving but I didn't get even half taht. I got more tread life out of my 911 rears and I frequented the track with it! The first 10K before rotation the tires were OK for an all season, I can't say good or bad they were adequate. The forums say to rotate these tires much earlier than the first service interval of 10K, pehaps that would have gotten me to 30K if I rotated at 5,000. I've got about a year left on my lease so I'm putting some BFGoodrich g-Force Sport COMP-2's on the CC. At $100 per corner I feel they will be much better than the OE tires and hopefully they last until I turn them in at lease end and the price was great.
