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.
o 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
ult 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. 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. 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
approximately 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:
80 ft.lb. (1 10 Nm).

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

and possibly an accident.
Rotating wheels:
The wheels can be rotated ac-
cording 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.
