A "rag joint" is a damper put into the steering mechanism, Look at any 60s Corvette (or many other cars) at a show and you can't miss it. Basically the wheels keep shaking but the vibration is intercepted before it gets to the steering wheel.

The other approach is to get the tires ( which are not dimensionally round) shaved so that they are round. Very little rubber is removed if the job is done correctly.
