 We have just turned 5,000 miles and have been told we already need new tires.  We have been experiencing horrible noises and grabbing when turning sharply. After our dealer checked it out for 2 days they claimed it was because of our tires and cold weather.  However, we live in Houston,Tx where it is rarely cold and experienced these noises when it was 90 degrees outside.  We are now putting 4 new tires on the vehicle because it seems we have no choice as they will not align it without new tires! We hope this fixes this, but we are more than upset that these expensive tires get only 5,000 miles before needing replacing. The dealer indicated we should have known that an AMG would need new tires frequently.  Funny no one mentioned this when we were buying the car.
