Volkswagen Golf Service & Repair Manual: Vibration, vibration control system

Using the vibration control system -VAS 6230 A- you can perform more functions than just stationary balancing.
A special feature of this system is the testing of the radial force of the wheel and tyre while rolling.
A roller presses against the wheel with a force of about 635 kg. This simulates the vertical tyre force against the road surface during travel.
Radial and lateral run-out in the wheel and tyre and differences in the stiffness of the tyre cause the vertical force of the wheel to vary.
The -VAS 6230 A- detects and stores the position of the maximum measured radial force in the tyre. Then the position of the smallest distance between the wheel rim flange and the centre of the rim is measured.
