Just a note... If your tire gauge is messed up, the ride can get harsh because the tires could be overinflated and not indicate as such. Also, using summer tires in freezing or near freezing temperatures can have adverse effects on ride quality as well; usually within the first few minutes of driving a cold car.
The tire is a spring and has to be accounted for in the circuit between the road and the chassis.
