Tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
summer tyres: 3 mm
R
M+S tyres: 4 mm
R
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached.
Selecting, fitting and renewing tyres
Only fit tyres and wheels of the same type and
R
make.
If you change wheel size when installing new
R
tyres, make sure they correspond to the cor-
rect wheel size category (
assignment changes without recoding the
control units in the vehicle, the speedometer
will not display the speed accurately. Driving
safety systems and driving systems may then
be operationally impaired or may detect a
fault and switch themselves off.
Only fit tyres of the correct size onto the
R
wheels.
Run in new tyres at moderate speeds for the
R
first 100 km.
Do not drive with tyres which have too little
R
tread depth, as this significantly reduces the
traction on wet roads (aquaplaning).
Replace the tyres after six years at the latest,
R
regardless of wear. This also applies to the
spare wheel.

General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
If you install M+S tyres and change the wheel
size, make sure they correspond to the correct

ment changes without recoding the control
units in the vehicle, the speedometer will not
display the speed accurately. Driving safety sys-
tems and driving systems may then be opera-
tionally impaired or may detect a fault and
switch themselves off.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle (
Snow chains cannot be fitted on all wheel/tyre
combinations. Observe the restrictions on the
use of snow chains under "Wheel/tyre Combi-
Y
nations" ( page 381).
Also observe the notes in the "Changing a
Y
wheel" section ( page 376).
Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.

WARNING
Wheel and tyre dimensions as well as the type
of tyre can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is fitted, driving characteristics may be
severely affected. There is a risk of an acci-
dent.
To prevent risks:
you should therefore adapt your driving
R
style and drive carefully.
never fit more than one spare wheel that
R
differs from the wheel to be replaced.
