The Vehicle Application of Tire/Wheel Rolling Smoothness Controls

Increased emphasis on high speed vehicle rolling smoothness may be attributed to the growing network of Interstate highways.

Tire/wheel vibration inputs which disturb highway rolling smoothness are measurable in terms of force variation of the tires, and runout variation of the wheels.

New techniques are available to screen and correct for excessive tire and wheel variations. These techniques apply to the tires or wheels individually; or to the tire/wheel assembly.

Tire/wheel assembly screening and tire honing correction is a unique method which has been implemented at Cadillac Motor Car Division. This improvement was adopted to enhance the luxury ride of the Fleetwood Eldorado vehicle during the 1970 model run.
