Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Center for further
information.
See your authorized Mercedes-Benz Center 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 and rear tires should be replaced in sets.
Furthermore - in the event of tire replacement - the
spare wheel (except Sport Package version), if possible,
should be used on the rear axle. Rims and tires must be
of the correct size and type. For dimensions, see
page 273.
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
fastened to a tightening torque of 80 ft.lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, see page 273.

Wheel rotation applies only when winter tires are
mounted on all four 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 as
recommended by the tire manufacturer, 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!
Unid irectional tires must a lways be mou nted w it h a rrow
on tire sidewall pointing in direction of vehicle forward
movement.
Notes:
Wa r n i n g !
When replacing a tire on the 9
1/2 J x 18 H2 (Sport
Package SL 500) or 10 J x 18 H2 (Sport Package
SL 600) wheel rim, removal or mounting must only
be done over the back flange. Removal or
installation over the front flange will cause rim/
tire failure leading to serious or fatal injury.
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 specified for the particular rim
type. Failure to do so can result in the bolts
loosening and possibly an accident.
