2.8 CHECKING WHEEL RIM
General
1.
Check the wheel rims for the following:
-
deformation of the wheel rims and
wheel disc.
-
deformation or cracking of the wheel
stud holes.
-
corrosion, including on the tyre side of
the rim and on the rim ring.
2.
Cracked or damaged wheel rims or wheel
rims with cracked or deformed wheel stud
holes must be replaced.
Welding or repairing wheel rims in any way
is prohibited. Welds will crack again in the
course of time due to the dynamic load.
When taking a damaged wheel rim
off the vehicle, deflate the tyre
(remove the tyre valve), because of
possible tensions in the wheel rim.
3.
To prevent damage to the tyre due to
corrosion and/or indirect tension cracks
(due to notching), the anti-corrosion
treatment of the wheel rim must not be
damaged in any way.
For removal of corrosion and repairing the
paint layer, see “Paint treatment”.
Before re-spraying, remove the old layer of
paint to prevent the paint layer from
becoming too thick. The total layer of paint
must not be more than 50 microns thick.
If the paint layer is more than 50
microns thick in total (wash primer
and finishing paint), the pre-tension
of the wheel studs could be
reduced if this layer were to be
crushed. This could result in the
wheel nuts coming loose.
