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 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
mounting bolts be retightened after
approximately 60-300 miles (100-500
km) 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.
