Important information about wheels and tyres
1)
Follow the regulations of the country you are driving in.
Fig.191 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.190. The letters “TWI” or
triangles on the sidewall of the tyre mark the
position of the wear indicators.
The minimum permitted prole depth

have
been reached when the tyres have worn down
to the wear indicators. Replace the tyres with
new ones ››› .
With a sporty driving style, check the tread
depth every 5,000 / 10,000km (3,000 /
6,000mi). When checking the tread depth,
check the wear indicators in all the tyre
grooves.
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.191.
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 diicult 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 insuicient
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 aected.
●
The speed has to be adapted accordingly,
otherwise there is a risk of losing control over
the vehicle.
Wheel nuts
The wheel nuts and rims have been designed
to be part of an assembly. When installing
dierent wheels (for instance alloy wheels or
wheels with winter tyres) it is important to use
the correct wheel nuts with the right length
and correctly shaped bolt heads. This ensures
that wheels are tted securely and that the
brake system functions correctly.
The wheel nuts must be clean and turn easily.
A special adapter is required to turn the anti-
theft wheel nuts ›››page320.
Two-piece wheel nuts
Two-piece wheel nuts must be used for this
vehicle. In this type of bolt, the spherical collar
is not rmly attached to the head.
WARNING
Wheel nuts should never be greased or oiled.
●
Use only wheel nuts which belong to the
wheel.
●
If the required torque of the wheel nuts is
too low, they could loosen whilst the vehicle
is in motion. Risk of accident! If the tighten-
ing torque is too high, the wheel nuts and
threads can be damaged.
