Next I took it to the dealer,they performed a road balance and replaced rt rear tire and rebalanced the rest. Still has vibration,took it back again to dealer and they reindexed the rear tires on the wheels, car ran ok but still slight vibration,but the dealer scratched the rear rims.They tried to have them fixed but ended up replacing with new ones. Now the vibration is the worse it ever been.
I know about service bulletin 04-00-89-053C and 03-03-10-007E. I think GM has a issue with the Pirelli tires and does what to say so..If any one else is having this issues please speak up.

Wow every ones car rides great..
