W heels
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 con­
struction 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
advice concerning tire service and
purchase.
Tire Replacement
Front tires should be replaced in
sets. Furthermore - in the event of
tire replacement - the spare
wheel, if possible, should be used
on the rear axle. Rims and tires
must be of the same size and
type. For dimensions, see
''Technical Data".

We recommend that you break
in new tires for approx. 60 miles
(100 km) at moderate speed. It is
imperative that the wheel mount­
ing bolts be retightened after ap­
prox. 60-300 miles (100-500 km).
On new vehicles retightening is
carried out during the 1st inspec­
tion. Retightening is also neces­
sary 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 ft.lb. (150 Nm ).
For rim and tire specifications,
refer to ''Technical Data" .
Warning!
Worn, old tires can cause
accidents. 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 particu­
lar rim type. Failure to do so
can result in the bolts loosen-
ing and possibly an accident.
Rotating W heels
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 3000 -
6000 miles (5000 - 10 000 km),
before the characteristic tire wear
pattern (shoulder wear on front
wheels and tread center wear on
rear wheels) becomes visible, as
otherwise the driving properties
deteriorate.
Important!
Unidirectional snow tires must
always be mounted with arrow on
tire sidewall pointing in direction of
vehicle forward movement.
Note:
Thoroughly clean the inner side of
the wheels any time you rotate the
wheels or wash the vehicle
underside.
The use of retread tires is not
recommended. Retread tires may
adversely affect the handling
characteristics and safety of the
vehicle.
Dented or bent rims can cause tire

pressure loss and damage to the
