Operation CHARM: Car repair manuals for everyone.

Wheels: Testing and Inspection

Checking disc wheels
Checking the radial and lateral runout

Note!
^ Straightening and welding work on light alloy wheels is not permissible!





Maximum permissible radial runout and lateral runout of the light alloy wheels = 0.7 mm.
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.





Note!
^ Use a lyre measuring gauge - e.g. VAG. 1435 - to measure wheels without tyres and wheels with tyres.
