Wheels
Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. See your
authorized MERCEDES-BENZ dealer
for further information.
Warning!
Do not mix different tire construc­
tion types (i.e. radial, bias, and
bias-belted) on your car because
handling may be adversely
affected and may result in loss of
control.
See your authorized MERCEDES-
BENZ dealer for information on tested
and recommended rims and tires for
summer and winter operation. They
can also offer more advice concerning
tire service and purchase.
Tire replacement:
Front tires should be replaced in sets.
Furtherm ore- in the event of tire
replacement - the spare wheel, if pos­
sible, should be used on the rear axle.
Rims and tires must be of the same
size.
For dimensions see “Technical Data” .
We recommend that you break in new
tires for approx. 100 km (60 miles) at
moderate speed. It is imperative that
the wheel mounting bolts be retighten­
ed after approx. 1 00-500 km
(6 0 -3 0 0 miles).
On new vehicles retightening is carried
out during the 1 st inspection. Retighten­
ing is also necessary whenever wheels
are fitted, e.g. when the spare wheel is
used for the first time or when a set of
wheels with M +S tires is installed.
Tightening torque: 110 Nm (80 ft.lb.).
For rim and tire specifications, refer to
“Technical Data” .
Warning!
Worn, old tires can cause acci­
dents. If the tire tread is badly worn,
or if the tires have sustained
damage, replace them.
When replacing rims, use only
genuine MERCEDES-BENZ wheel
bolts (identified by Mercedes star)
specified for the rim type. Failure to
do so can result in the bolts loos­
ening and possibly an accident.
Rotating wheels:
The wheels can be rotated according to
the degree of tire wear while retaining
the same direction of travel.
Rotating, however, should be carried
out, at a mileage of 5 00 0 -1 0 000 km
(3000-6000 miles), before the charac­
teristic tire wear pattern (shoulder wear
on front wheels and tread center wear
on rear wheels) becomes visible, as
otherwise the driving properties dete­
riorate.
