WM 441202 Checking disc wheels

Checking the radial and lateral runout

Information

- 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 tyres and wheels without tyres, use a tyre measuring gauge, e.g. VAG. 1435, see Tools and Equipment.





Maximum permissible radial runout and lateral runout of the wheel with tyre = 1.25 mm. Values less than 1.0 mm - better around 0.5 mm - are desirable. For this purpose, match the tyre (turn the tyre 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 tyres, remove the wheel from the vehicle. -> 440519 Removing and installing wheel 44051900 Removing and installing wheel
2. Remove the tyre from the light alloy wheel. -> 444019 Fitting tyres for vehicles with and without Tire Pressure Monitoring (TPM) Removal and Replacement
3. Clamp the wheel on the balancing machine and measure at points -a-.
