TYRES (1/3)Maintaining the tyres
The tyres must be in good condition
and the tread form must have sufficient
depth; tyres approved by our Technical
Department have tread wear indica-
tors 1 which are indicators moulded
into the tread at several points .
Tyre and wheel safety
The tyres are the only contact between
the vehicle and the road, so it is essen-
tial to keep them in good condition. You
must make sure that your tyres conform
to local road traffic regulations. When the tyre tread has been eroded
to the level of the warning strips, they
become visible 2: it is then necessary
to replace your tyres because the tread
profile is no more than 1.6
mm deep
and this causes poor road holding
on wet roads.
An overloaded vehicle, long journeys
by motorway, particularly in very hot
weather, or continual driving on poorly
surfaced minor roads will lead to more
rapid tyre wear and affect safety.
Incidents which occur when
driving, such as striking the
kerb, may damage the tyres
and wheel rims, and could
also lead to misalignment of the
front or rear axle geometry. In this
case, have the condition of these
checked by an approved dealer.

For your safety, please re-
spect the speed limit.
When they need to be re-
placed, only tyres of the
same make, size, type and profile
should be used on a single axle.
They must: either have a load ca-
pacity and a speed capacity at
least equal to the original tyres,
or correspond to those recom-
mended by your authorised
dealer.
Failure to heed these instructions
could endanger your safety and
affect your vehicle’s roadworthi-
ness.
Risk of loss of control of the ve-
hicle.

Changing wheels around
This practice is not recommended.
Emergency spare wheel
Refer to the information on the
“Emergency spare wheel” and in-
structions on “Changing a wheel” in
Section 5.
Use in winter
– ChainsFor safety reasons, fitting snow
chains to the rear axle is strictly
forbidden.
Chains must not be fitted to tyres
which are larger than those originally
fitted to the vehicle.
Chains may only be fitted
to tyres of the same size
as those originally fitted to
your vehicle.
Only certain chains can be fitted to
tyres. Consult an approved Dealer.
– Snow or winter tyres We would recommend that these be
fitted to all four wheels to ensure
that your vehicle retains maximum
grip.
Note: be aware that these tyres may
sometimes have:
– a direction of travel ;
– a maximum speed index which
may be lower than the maximum
speed of your vehicle.
– Studded tyres This type of equipment may only be
used for a limited period and as laid
down by local legislation.
It is necessary to observe the speed
specified by current legislation.
These tyres must, at a minimum, be
fitted to the two front wheels.
In all cases, we would recommend
that you contact an approved dealer
who will be able to advise you on
the choice of equipment which is
most suitable for your vehicle.
