tyres, make sure it corresponds to the correct
wheel size category. If the wheel size category
changes, the vehicle control units must be reco-
ded at a qualified specialist workshop.
Otherwise the accuracy of the speedometer and
odometer displays will be outside the tolerance
as specified by law. It can also be lower, that is
the current driving speed is then faster than the
speed shown on the speedometer. If the devia-
tion is outside of the tolerance range, driving
safety systems and driving systems may be
operationally impaired or may detect a malfunc-
tion and switch themselves off. Additionally, the
display accuracy of the reversing camera or the
360° camera is impaired, since the wheel size is
important for its calibration.
Information on the dimensions and types of
wheels and tyres for your vehicle can be found

Modifications to the brake system or wheels are
not permitted. The use of spacers or brake dust
shields is not permitted. This invalidates the
general operating permit for the vehicle.
Further information on wheels and tyres can be
obtained at any qualified specialist workshop.
Operation
Information for a journey
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust
Y
( page 369).
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that
a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tyres for damage. Hidden
tyre damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tyres and wheels checked at a
qualified specialist workshop.

When parking your vehicle, make sure that the
tyres do not get deformed by the kerb or other
obstacles. If it is necessary to drive over kerbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tyres, particularly the sidewalls, may be dam-
aged.
Regular wheel and tyre checks

WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Check the wheels and tyres of your vehicle for
damage regularly, i.e. at least every two weeks,
as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of tyre
pressure. Pay particular attention to damage
such as:
cuts in the tyres
R
punctures
R
tears in the tyres
R
bulges on tyres
R
deformation or severe corrosion on wheels

Regularly check the tyre tread depth and the
condition of the tread across the whole width of
Y
all the tyres ( page 367). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tyre surface.
All wheels must have a valve cap to protect the
valve against the ingress of dirt and moisture.
Do not fit anything onto the valve other than the
standard valve cap or other valve caps approved
for your vehicle by Mercedes-Benz. Do not fit
any other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure if necessary (
The service life of tyres depends on various fac-
tors, including the following:
