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 Removal and Replacement
2. Remove the tyre from the light alloy wheel. -> 444019 Fitting tyres for vehicles with and without Tire Pressure Monitoring (TPM) 444019 Mounting tyres (removing and installing tyres)
3. Clamp the wheel on the balancing machine and measure at points -a-.
