Wheels and tyres
•
Check the tyres every day for damage and
air pressure, because the lifetime of tyres
depends on the air pressure.
•
Have cuts or breaks in the tyres repaired as
quickly as possible or change the tyres.
•
Do not expose tyres to oil, grease, fuel, chemi-
cals as well as prolonged direct exposure to
sunlight.
•
Drive carefully! Avoid driving over sharp
stones or edges.
•
The prescribed tyres and rims must be used.
•
The difference in tyre pressure between the
tyres on one axle must not exceed 0.1 bar
[1.45 psi].
•
During fast driving or hot ambient tempera-
ture the air pressure may rise by up to 1 bar
[14.5 psi]. Do not reduce the air pressure,
because it may then drop too low when cool-
ing down!
•
Repair work on tyres must only be carried
out by experts and by using appropriate as-
sembly tools.
•
Assembly work requires appropriate knowl-
edge and proper tools.

Air pressure of tyres
The required air pressure in the tyres depends
on:
•
Tyre size
•
Load bearing capacity of the tyres
•
Travel speed
The performance of tyres is reduced by:
•
Overloading
•
air pressure in tyres too low
•
air pressure in tyres too high
