Tyres and wheels
229Direction of rotation
Direction of rotation Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i You may fit a spare tyre* against the
direction of rotation. MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 30
. It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when fitting tyres that do not feature run-
flat properties, e.g. winter tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y page 328). Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
You should thus replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less because oth-
erwise they no longer provide adequate
grip.
R the tread on a tyre may not wear evenly.
You should thus regularly check the tread depth and the condition of the tread
across the entire width of all tyres. If nec-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’s
driving safety, which could lead you to
cause an accident. You should therefore
regularly check the pressure of all your
tyres (including the spare tyre*), particu-
larly prior to long trips, and correct the
pressure as necessary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres-
sure can be checked in the on-board com-
puter.

Tyres and wheels
230
If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be
adapted according to the specifications given
in the fuel filler flap (Y page 218).
Use the highest specified tyre pressure for
the spare wheel*. G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking.
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident.
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres. Therefore, you should only correct tyre pres-
sures when the tyres are cold.
The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions.
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
E 350 CGI 31
/E 300 BLUETEC: the values on
the tyre pressure information label (fuel filler
flap) are for the use of the vehicle in partially
laden and fully laden condition whilst driving
at maximum speed.
Despite what is stated on the tyre pressure
information label, for speeds up to
210 km/h the values stated can be reduced
as follows, without a reduction in safety:
-0.4 bar /-6 psi: E 350 CGI
-0.3 bar/-4 psi: E 300 BLUETEC This improves the ride comfort of your vehi-
cle, however the fuel consumption could
increase slightly.
Also check the tyre pressure of the spare
wheel*. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning system
G
Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check
your vehicle's tyre pressures, since an even
loss of pressure on several tyres at the
same time cannot be detected by the tyre
pressure loss warning system.
The tyre pressure loss warning system is
not able to warn you of a sudden loss of
