#
Steel wheels: tighten the wheel bolts or
wheel nuts evenly in a crosswise pattern in
the sequence indicated (1 to 5) and to a
maximum of 200 Nm.
#
Light-alloy wheels: tighten the wheel bolts
or wheel nuts evenly in a crosswise pattern in
the sequence indicated (1 to 5) and to a
maximum of 180 Nm.
#
Check the tyre pressure of the newly fitted
wheel and adjust it if necessary.
Vehicles with the tyre pressure monitor sys‐
tem: all fitted wheels must be equipped with
functioning sensors.
#
Retighten the wheel bolts to the specified
tightening torque after the vehicle has been
driven 50 km.
%
When using a wheel or spare wheel with a
new or newly painted disk wheel, have the
wheel bolts or wheel nuts retightened again
after approximately 1,000 to 5,000 km.
Observe the specified tightening torque.
Information on wheel and tyre combinations
General notes
Retreaded tyres are not checked and recommen‐
ded by Mercedes-Benz as it is not always possi‐
ble to detect previous damage after retreading.
For this reason, Mercedes-Benz cannot guarantee
their driving safety. Do not use used tyres when
their previous usage is unknown.
For safety reasons, Mercedes-Benz recommends
that you only use tyres, wheels and accessories
which have been approved by Mercedes-Benz for
your vehicle.
These tyres have been specially adapted for use
with driving safety systems, such as ABS or
ESP
®
.
Only use tyres, wheels and accessories that have
been checked and recommended by Mercedes-
Benz. Certain characteristics, such as handling,
vehicle noise emissions, fuel consumption, etc.
may otherwise be adversely affected. Other
wheel sizes may cause the tyres to come into
contact with the vehicle body and axle compo‐
nents when under load. This may result in dam‐
age to the tyre or the vehicle.
Mercedes-Benz is not responsible for any damage
caused by using tyres, wheels or accessories
other than those recommended.
Information on tyres, wheels and permissible
combinations can be obtained at a qualified spe‐
cialist workshop.
The smaller the cross-section of a tyre of a spe‐
cific wheel size, the worse the driving comfort on
poor road surfaces. Ride and damping comfort
are reduced and the risk increases that when you
drive over obstacles, damage to wheels and tyres
may result.
If you change wheel size on your vehicle, check it
is assigned to the correct wheel size category
(/ page 324). If the assignment changes with‐
out recoding the control units in the vehicle, the
speedometer will not display the speed accu‐
rately. Driving safety systems and driving systems
may then be operationally impaired or may detect
a malfunction and switch themselves off.
You will find a table with the recommended tyre
pressures for various vehicle loads on the inside
of the vehicle's fuel filler flap or under "Tyre pres‐
sure tables" (/ page 317).
Check tyre pressures regularly and only when the
tyres are cold.
Observe the following notes:
R
always fit the vehicle with tyres of the same
size on a given axle (left/right)
R
always fit the same type of wheels on your
vehicle at a given time (summer tyres, winter
tyres)
You can obtain information about tyres that have
been specially designed and approved for your
vehicle from a Mercedes-Benz Service Centre.

Not all wheel/tyre combinations can be fitted
at the factory in all countries.
