TYRES (continued)
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 false
information which could have
serious consequences.
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.
Incorrect tyre pressures
lead to abnormal tyre
wear and unusually hot
running. These are factors
which may seriously affect safety
and lead to:
- poor roadholding;
- the risk of blow-outs or of
throwing a tread at high speed.
Tyre pressures depend on the
load and the driving speed.
Adjust the pressures according to
the conditions of use. (Refer to
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 the
country or model) fixed to the edge
or frame of the driver’s door gives
the recommended tyre pressures.

Refer to the information on
Emergency spare wheel and
Changing a wheel in Section 5.
Tyre pressures
Tyre pressures must be adhered to,
tyre pressures for all wheels
(including the emergency spare
wheel) must be checked at least
once a month and always before a
long journey (refer to the
information on Tyre pressures).
