    "@$$hole" is one word, not two. And the use of "months" in your post should be possessive, "month's."

    I guess we have to award a consolation prize.

    I have the 19" Summer Tire package on my 2011 CTS-V and have no problem whatsoever.

    I have a 2013 CTS Coupe with the 19" wheel package & I'm just beginning to experience the sound when backing with my wheel turned almost all the way. At this moment I've only experienced this twice, and it has been extremely cold outside. My car is only 3 months old. I will definitely contact the dealership to see if this can be resolved.

    It's normal with those tires and the way the wheels are aligned (negative CAMBER). It will go away if you install all season tires with a softer compound.

    Added: from the Corvette Forum;
    It is the result of the Ackerman steering angle geometry being adjusted to favor high speed driving at the expense of slow speed turning. Cold temperatures affect the grip of the tires, and make it more noticeable. So yes it does get worse at colder temps.

    For a good explanation of "Ackerman steering" do a Google search of the term. I highly recommend you at least read Wikipedia's article first.

    It is normal for a high performance handling automobile. Most of us have never driven automobiles that were engineered for ultimate handling, and were never exposed to this behavior.

    This condition was very severe on my car with the original ContiSportContact 3s (car has 19 in. summer performance package). Every time I Backed from my driveway into the street there would be a loud Bang!-- sounding and feeling like something had broken, but it hadn't, of course. Same thing would happen backing out of parking spaces, but usually not as loud, probably because parking lot concrete is generally not as coarse as my driveway. Last week I replaced the Continentals with Michelin Pilot Sport A/S 3s, and the condition is absolutely gone! The car is also surprisingly quieter with the Michelins.

    Laura, tell your production friends to get rid of those Continentals and start putting Michelins on the cars!

    I have noticed this a bit with the V now that it has gotten colder. Never noticed in with my AWD coupe before.

    Thanks Zen. That makes a lot of sense of what you described. I'll do more research on it. Actually I had a 2012 C6 Vette that made a weird noise (when cold & after sitting still for a long time) and I proceed to turn just from the parking space going forward. I know it has to be the angle of these extra wide tires at low speeds.

First, there is no noise, when turning moderately to full lock and applying the accelerator, my car begins to violently hop from both ends of the vehicle. I've read about the rear tires sliding, and so on. I've taken my car to a parking lot following a re-sealed transfer case "fix". The car continued to hop. Here's my input... Yes, initially accelerating causes the car to violently hop, but after a few seconds, my car was able to continue turning, full lock, with no hopping, no loss of traction. As soon as I adjusted the steering wheel, the hop returned. Input?
    If they didn't ad GM limited slip differential additive to the case and differential, you might try that.
