Tyres and wheels
186
i
Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
36
kit.
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
( page 272).

Tyre tread
G
Risk of accident
Bear in mind that:
tyre grip decreases rapidly on wet roads
R
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
winter tyres should be replaced when the
R
tread depth is 4 mm or less as they will no
longer provide adequate grip.
the tread on a tyre may not wear evenly.
R
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the front wheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road.
Tyre pressures
i
You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
36 Only for certain countries.
The applicable value for the "Minispare"
emergency spare wheel* is stated on the
spare wheel and in the technical data sec-
tion.
The load condition "partially laden" or "fully
laden" is defined in the table by the differing
number of passengers and amount of lug-
gage. The actual number of seats may vary
from this – more information can be found on
the vehicle's registration document.
If no other data is stated, the tyre pressures
specified on the fuel filler flap apply for all
tyres approved for this vehicle.
If a tyre size precedes a tyre pressure, the tyre
pressure information following is only valid
for that tyre size.
Instead of the complete tyre size, it may be
that only the rim diameter is stated, e.g.
R 16 or 16".
