Wheels: Testing and Inspection

Checking the radial and lateral runout

Note:
^ Straightening and welding work on light alloy wheels is not permissible.
^ The work is carried out initially with the wheel mounted on the vehicle.





^ To measure wheels with tires and wheels without tires, use a tire measuring gauge, e.g. VAG. 1435, see Workshop Equipment Manual, Chapter 3.4.2.

Maximum permissible radial runout and lateral runout of the wheel with tire = 1.25 mm. Values less than 1.0 mm - better around 0.5 mm - are desirable. For this purpose, match the tire (turn the tire on the rim) if necessary.).





Maximum permissible radial runout and lateral runout -a- of the light alloy wheels = 0.7 mm.
If in isolated cases further measurements are necessary, carry out the following procedure.

1. To measure wheels without tires, remove the wheel from the vehicle.
2. Remove tire from the alloy wheel.
3. Clamp the wheel on the balancing machine and measure at the points -a-.
