3.3 Prole depth
3.4 Rims
New tires are needed (at the latest) when the
prole depth measures 1.6 mm.
Tires age even when used rarely or
not at all.
Tire manufacturers' recommendation
• Change tires after six years, regardless of
prole depth.
• Avoid striking curbs, potholes or other
obstacles.
Use only those rims indicated in the general op-
erating permission documents. If you would like
to use other rims, you must consider the follow-
ing points:
Rules for the use of other rims:
- Size,
- mechanisms,
- compression depth and
- the load/bearing capacity must be sufcient
for the permissible total mass.
- The chuck cone of the fastening screw must
correspond to the rim mechanisms.
Modications can only be made with
the manufacturer's permission.
The exact specications can be
found in the general operation per-
mission documents.
Rules for wheel screws:
- Wheel screws should rst be tightened after
50 km, then every 500 km.
Adjusting torque
- for steel rims: 110 Nm
- for aluminium rims: 120 Nm
WARNING: When changing rims
(steel -> aluminium / aluminium ->
steel) ensure that you are using the
correct wheel screws.
