My teeth rattle over a minor pot hole, I go airborne over the railroad tracks. I can't stand how hard of a ride this car is! It is a beautiful 2007 ice silver sports wagon , only 16 K miles. Before I trade it in and take a bath on the depreciation, can anyone suggest what I can do to soften the ride? I am willing to try ANYTHING. I have heard that changing the run flat tires

to regular tires might help. Any considerations on tire size If I do this?. PLEASE help
