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 construction
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 mounting bolts be
retightened after approx. 60-300 miles
(100-500 km).
On new vehicles retightening is carried
out during the 1st inspection.
Retightening 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 ft.lb. (150 Nm).
For rim and tire specifications, refer to
"Technical Data".
Warning!
Worn, old tires can cause accidents. If
the fire 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 particular rim type.
Failure to do so can result in the bolts
loosening 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 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
