·
If the tyre pressure is too low or too
high, the tyres will wear prema
turely
and the vehicle will not handle well.
·
If the tyre is not flat and it is not neces-
sary to change the wheel immediately,
drive at low speed to the nearest corre-
spondingly qualified workshop and
have the tyre pressure checked and
corrected → page 339.

Introduction
T
he tyres are the most used and most un-
derestimated parts of a vehicle. Tyres are
very important as the narrow tyre surfaces
are the only contact between the vehicle
and the road.
The service life of tyres is dependent on
tyre pressure, driving style, handling and
correct fitting.
It is recommended to have work on tyres
and wheels carried out by a qualified work-
shop. They are familiar with the procedure
and have the necessary special tools and
spare parts and the proper facilities for dis-
posing of the old tyres.
WARNING
New tyres or tyres which are old, worn
down or dama
ged cannot provide full lev-
els of vehicle control and braking power.
Incorrect handling of wheels and tyres
can reduce vehicle safety and cause acci-
dents and serious injuries.
·
All four wheels must be fitted with radi-
al tyres of the same type, size (rolling
circumference) and the same tread
pattern.
·
New tyres will have to be run in as they
will initially have reduced grip and brak-
ing eect. Drive particularly carefully for
the first 600 km (370 miles) in order to
prevent accidents and serious injury.
·
Check the tyre pressure regularly when
the tyres are cold and always observe
the specified value. If the tyre pressure
is too low, it is possible that the tyre
temperature will increase to such an
extent when driving tha
t the tread peels
o and the tyre bursts.
·
Check the tyres regularly for damage
and wear.
·
Never drive with worn tyres or tyres that
shows signs of damage such as holes,
cuts, cracks or blisters. Driving with
tyres in this condition can result in
blown tyres, accidents and serious inju-
ries. Replace worn or damaged tyres
immediately.
·
Never exceed the top speed and load
permitted for the fitted tyres.
·
The eectiveness of the driver assis-
tance systems and brake support sys-
tems depends on the tyre grip.
·
If you notice unusual vibration, or if the
vehicle pulls to one side when driving,
stop immediately and check the wheels
and tyres for damage.
·
In order to reduce the risk of losing con-
trol of the vehicle, and the risk of acci-
dent and serious injury, never loosen
the bolts on rims with bolted-on rim
rings.
·
Do not use wheels or tyres if you do not
know their history. Used wheels and
tyres may be damaged, even if the
damage is not visible. This can cause
tyre damage, tyre failure and loss of
control of the vehicle.
·
Even if they have not been used, old
tyres can suddenly lose pressure or
burst, especially at high speeds, and
thus cause accidents and serious inju-
ries. Use tyres that are more than
6 years old only if you have no alterna-
tive. In this case, drive slowly and with
extra care at all times.
WARNING
If the wheels are incorrectly fastened or if
wheel bolts are missing, the wheels c
ould
come loose, leading to a loss of control of
the vehicle, causing accidents and serious
injuries.
·
Never drive if wheel bolts are missing or
loose.
·
Always use wheel bolts that match the
wheel rims and the vehicle type.
