un in new tyres. Drive with appropriate
care during the first 600 km
(370 miles).
New tyre sizes may dier signific
antly
from the actual dimensions and tyre
dimensions for dierent tyre brands.
Replacing tyres
— Always replace tyres at least on an axle-
by-axle basis.
— Old tyres should only be replaced by
tyres that have been approved for the ve-
hicle type.
— Never use tyres with an eective size that
is larger than tyres approved for the vehi-
cle →
.
In vehicl
es with a Tyre Pressure Loss In-
dicator
The Tyre Pressure Loss Indicator must be
resynchronised aer changing one or more
wheels. This also applies if the wheels have
been swapped, e.g. from the front to the
rear → page 356.
Vehicles tted with a Tyre Pressure
Monitoring System
— If you wish to replace factory-fitted
wheels, make sure that the new wheels
are equipped with sensors that are com-
patible with the TPM → page 360.
— Drive the vehicle at a speed of over
around 25 km/h (around 15 mph) for an
extended period so that the new wheels
can be detected.
Further information on the TPM
→ page 360.
WARNING
Incorrect replacement or conversion of
the sensors of the T
yre Pressure Monitor-
ing System can cause the valves to leak,
with the result that the tyre loses air.
If the tyre pressure is too low, it is possible
that the tyre will heat up to such an ex-
tent when driving that this can result in
tread separation and the tyre bursting,
which can cause serious accidents and
fatal injuries.
·
When replacing and converting sensors,
always use a new valve set.
WARNING
Wheels must have the necessary clear-
anc
e. If there is insucient clearance, the
tyres may rub against parts of the running
gear, body and brake lines.
This can lead to failure of the brake sys-
tem, separation of the tread or the tyre
bursting, and can thus cause serious acci-
dents and fatal injuries.
·
Use only tyres whose dimensions do
not exceed the dimensions of tyre
makes approved for the vehicle and
that do not rub on any vehicle parts.
WARNING
Dirt can damage the valves and cause
them to leak so that the tyre loses air.
If the tyre pressure is too low, it is possible
that the tyre will heat up to such an ex-
tent when driving that this can result in
tread separation and the tyre bursting,
which can cause serious accidents and
fatal injuries.
·
Never drive without valve caps.
NOTICE
Tyres can be deformed by driving through
potholes and over kerb
s.
This can cause damage to the tyres and
wheels.
·
Avoid heavy impacts and drive around
obstacles if possible.
NOTICE
The valves can be damaged when fitting
dierent wheels.
·
Do not allow wheels tha
t have been re-
moved to fall onto the wheel rim.
Old tyres should be disposed of prop-
erly and a
s required by legislation.
If the spare tyre is not the same as the
tyres that are mounted on the car - for
example in the case of winter tyres or
a temporary spare wheel - only use the
spare tyre in the event of a breakdown for
a short period of time and drive with extra
care. Replace the temporary spare wheel
with a normal wheel as soon as possible.
