Checking wheel rims

Checking radial and lateral runout

Radial and lateral runout must be measured at the points on the inside of the wheel rim shown on the following drawing (dimension "a").


For measurements on wheels with or without tires, use a tire runout gage, e.g. V.A.G 1435

The maximum allowable radial and lateral runout on light alloy wheels is 0.7 mm.

The maximum allowable radial and lateral runout on wheels with tires is 1.25 mm. Values lower than 1.0 mm (preferably around 0.5 mm) should be aimed for. See also page 44-23.

Caution: Welding and straightening work on light alloy wheels is not allowed.


Dimension "a" = 8 mm
