your dealer is blowing smoke if you beleive a perfromance package...all summer tires is for highway only......you need to get a good road force balance done on all wheels using a good hunter machine and a mechanic who knows how to properly balance a wheel...
Im betting that will solve your problem....not all tire shops or dealers have this machine...

Please post the bulletin # you wrote of in item # 31. I'm having vibration and rumbling noises at speeds between 40-65 MPH. Dealer want's me to let the tires run in for 7-8,000 miles. The vibration is worse at 42-43 MPH and in a slight pull or trying to maintain that speed straight and level.

The Technical Service Bulletin (TSB) = 08-07-30-044 (reflashed TCM with software modification per bulletin).
I had the same issue as you are describing. Totally resolved after applying this TSB by my dealer. There is a warning with the TSB that the mpg may go down. Haven't noticed anything significant sofar.
It made all the difference to me. Highly recommend the solution. My CTS is once again just one great car. Wouldn't trade it for anything else.

You are exactly describing a problem I had with my 2009 CTS at16,000 miles. Dealer replaced front wheel bearing. Problem solved.
