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 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.

NOTE:
  • Use a tire measuring gauge - for example, V.A.G. 1435 - to measure wheels without tires and wheels with tires.
