tyre load rating and speed rating required for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These
requirements can stipulate a specific tyre
type for your vehicle. Furthermore, the use of
certain tyre types in certain regions and areas
of operation can be highly beneficial. You can
find further information regarding tyres at
specialist tyre retailers, at qualified specialist
workshops or at any Mercedes-Benz Service
Centre.
Only fit tyres and wheels of the same type
R
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics" section
(
page 296).
Y
Only fit tyres of the correct size onto the
R
wheels.
Run in new tyres at moderate speeds for
R
the first 100 km. They only reach their full
performance after this distance.
Do not drive with tyres which have too little
R
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
Replace the tyres after six years at the lat-
R
est, regardless of wear.
Observe the notes on the emergency spare
wheel (
page 334).
Y
MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
Only use MOExtended tyres in conjunction
with an activated tyre pressure loss warning
system or tyre pressure monitoring system
and only on tyres specifically inspected by
Mercedes‑Benz.
Notes on driving with MOExtended tyres with
a flat tyre (
page 296).
Y
i
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist workshop.
Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (
page 323).
Y
Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi-
cle 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.
G
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.
M+S tyres
WARNING
G
M+S tyres with a tyre tread depth of less than
4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
