Why does my car shimmy, or sway when I go over dirt on a road, and some bumps. It only happens on the back end of the car. The front is fine. I have great new tires on the front, but the dealer had two different kinds of tires on the car. The front had tiger paw the rear are continental. The rear tread is ok but not brand new like the front. I tried to put a 40# bag of salt in the back but it does not seem to help. It feels like the car slips in the rear when it happens, just like going over ice but not as bad.
