Maintaining the tyres
The tyres are the only contact between
thevehicleandtheroad,soitises
sential to keep them in good condition.
You must make sure that your tyres
conformtolocalroadtrafficregula
tions.
The tyres must be in good condition
and the tread form must have sufficient
depth; tyres approved by our Technical
Department have wear warning strips
1
which are indicators moulded into
the tread at several points.
When the tyre tread has been worn to
the level of the wear indicators, they
become visible
2
: it is then neces
sary to replace your tyres because
the tread rubber is 1.6 mm deep at
most, resulting in 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.
Tyre pressures
Adhere to the tyre pressures (including
the emergency spare wheel). The tyre
pressures should be checked at least
once a month and additionally before
anylongjourney(refertothelabelaf
fixed to the edge of the driver's door).
Incorrect tyre pres
sures lead to abnormal
tyre wear and unusually
hot running. These are
factors which may seriously affect
safety and lead to:
– poor road holding;
– the risk of blow-outs or of
throwing a tread.
The pressure depends on the
load and the speed of use. Adjust
the pressure according to the
conditionsofuse(refertothela
bel affixed to the edge of the
driver's door 🡺329).
Pressures should be checked when

sures which may be reached in hot
weather or after driving at high speed.
If tyre pressures cannot be checked
when the tyres are cold, the pressure
values indicated must be increased
by 0.2 to 0.3 bar (or 3 PSI).
Never deflate a hot tyre.
