330xi

Does anyone else have any problems with the ride of a 2006 330xi? In my opinion it is way too hard. When I go over a minor bump in the road, let alone a pothole or a drain cover, it rattles the fillings in your teeth! I have driven nothing but 5 series BMW's for the last 30 years, but the ride of this car is ridiculous. In the first 6 months of owning this car I have replaced 3 tires and 4 rims! At a cost of $3,000! BMW says that's the way the ride is supposed to be due to the low profile run-flat tires.
