Tyres and wheels
318
wheels may come into contact with the
body or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
G
Risk of accident
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident. Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
Notes on selecting, fitting and replac-
ing tyres
Only fit tyres and wheels of the same type
R
and make.
Only fit tyres of the correct size onto the
R
wheels.
After fitting new tyres, run them in at mod-
R
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
Fit new tyres on the front wheels first if
R
tyres of the same size are required on the
front and rear wheels.
Version: 2.11.7.7
Replace the tyres after six years at the lat-
R
est, regardless of wear. This also applies to
the spare wheel*.
Do not drive with tyres which have too little
R
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting 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 spare tyre*, particularly prior
to long trips, and correct the pressure as
necessary (
page 319).
Y
Notes on driving
While driving, pay attention to vibrations,
R
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
