Every bump is not only felt but exaggerated.
What are your tire pressures?
And what type of tires? Summer tires will give a harsher ride than all-season tires.
Different brands of tire will also differ in ride quality and almost all 255/35/18 (OEM Crossfire tires) are XL (meaning Extra Load).
They don't have to be for a 3050 lb Crossfire, the XL load rating is for all the heavier cars they fit, some of which are SUVS.
