Wheels and tyres Important information about wheels and tyres

Fig. 197 Interchanging tyres.
Wear indicators around 1.6 mm high can be
found on the base of the original tyre treads,
ordered at regular intervals and running across
the tread

Fig. 196 . The letters “TWI” or
triangles on the sidewall of the tyre mark the
position of the wear indicators.
The minimum permitted profile depth

tyres have worn down to the wear indicators.

Changing wheels around
In order to wear the wheels in a uniform man-
ner, it is recommended to interchange them
regularly according to the diagram
›››
Fig. 197 .
The useful life of all the tyres will then be about
the same time.
WARNING
The tyres must be replaced at the latest when
the tread is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
• Particularly in difficult driving conditions
such as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
• The scant driving safety due to insufficient
tread depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
•
The speed has to be adapted accordingly,
otherwise there is a risk of losing control over
the vehicle.
Wheel nuts
The wheel bolts and rims have been designed
to be part of an assembly. When installing
different wheels (for instance alloy wheels or
wheels with winter tyres) it is important to use
the correct wheel bolts with the right length
and correctly shaped bolt heads. This ensures
that wheels are fitted securely and that the
brake system functions correctly.
The wheel bolts must be clean and turn easily.
A special adapter is required to turn the anti-
theft wheel bolts

Two-piece wheel bolts
Two-piece wheel bolts must be used for this
vehicle. In this type of bolt, the spherical collar
is not firmly attached to the head.
WARNING
Wheel nuts should never be greased or oiled.
•
Use only wheel bolts which belong to the
wheel.
• If the prescribed torque of the wheel bolts
is too low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged.
NOTICE

to find out the recommen-
ded tightening torque for wheel nuts for steel
and alloy rims.
Winter tyres
•
Winter tyres must be fitted on all four
wheels.
• Only use winter tyres that are approved for
your vehicle.
