TYRES
(continued)
Tyre pressures
Tyre pressures must be adhered to,
tyre
pressures
for
all
wheels
(including the spare wheel) must be
checked at least once a month and
always before a long journey (refer
to
the
information
on
“Tyre
pressures”).
Incorrect tyre pressures
lead to abnormal tyre
wear and unusually hot
running, factors which
may seriously affect safety and
lead to:
- poor roadholding;
- the risk of blow-outs or of
throwing a tread at high speed.
The tyre pressure depends on the
load and speed of use; adjust the
pressures
according
to
the
conditions of use (refer to the
information on Tyre pressures).
Pressures should be checked when
the tyres are cold; ignore higher
pressures which may be reached in
hot weather or following a fast
journey.
If tyre pressures cannot be checked
when the tyres are
cold
, assume an
increase of
0.2
to
0.3
bar (3 PSI).
Never deflate a hot tyre.
Note:
a label (depending on country
or model) fixed to the edge or frame
of the driver's door gives the
recommended tyre pressures.
Swapping wheels
Each
of
the
sensors
incorporated
in
the
valves is dedicated to a
single wheel: under no
circumstances should you swap
the wheels.
There is a risk of incorrect
information which could have
serious consequences.
Fitting new tyres
For safety reasons, this
operation
must
be
carried
out
by
a
specialist.
Fitting
different
tyres
may
change your vehicle as follows:
- It may mean that your vehicle
no longer conforms to current
regulations.
- It may change the way it
handles when cornering.
- It may cause the steering to be
heavy.
- It may cause tyre noise.
- It may affect the use of snow
chains.
Emergency spare wheel
Refer to the information on the
“spare wheel” and “changing a
wheel” in Section 5.
