The lower the side wall height on a tire the less flex thus a greater amount of impact is going to be translated to the cabin of the car.

I am assuming your car has 215/50 X 17 tires? Try trading the wheels and tires with another car that has the standard recommended whiles and tires. You can find the recommended tire sizes by looking in the driver's door jam or your owners manual.

Keep us posted,
