Maintenance And Care Of Wheels And Tyres; Tyre Pressures - Mercedes-Benz E-Class 2010 Owner's Manual

example at a Mercedes-Benz Service
Centre.
When parking your vehicle, make sure that
R
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged.
Maintenance and care of wheels and
tyres
Checking wheels and tyres
Regularly check the wheels and tyres of
R
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
Regularly check the tyre tread depth and
R
the condition of the tread across the whole
width of the tyre (
Y
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
All wheels must have a valve cap to protect
R
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
Regularly check the pressure of all the tyres
R
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correct the pressure as necessary
( page 299).

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 steering wheel so that you can see
the tyre tread more easily.
You could otherwise lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road.
Storing tyres
Store tyres that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel.
Cleaning tyres
!
Do not use a high pressure jet with circu-
lar jet nozzles (concentrated-power jets) to
clean the tyres. The high pressure of the
water jet could damage the tyres. Always
replace damaged tyres.

Tyre pressures

Recommended tyre pressures
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
