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 274.
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 274.

Rotating wheels
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.
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.

that it is always vertical (plumb-line) as seen from 
the side (see arrow), especially if the vehicle is 
parked on an incline.
9. Jack up the vehicle until the wheel is clear of the 
ground. Never start engine while vehicle is raised.

alignment bolt (1) supplied in the tool kit. Remove 
the remaining bolts. Keep bolt threads protected 
from dirt and sand.11. Remove wheel. Grip wheel from the sides. Keep 
hands from beneath the wheels.
12. Clean contact surfaces of wheel and wheel hub. 
Install spare wheel on wheel hub. Insert wheel bolts 
and tighten them slightly.
To avoid paint damage, place wheel flat against hub 
and hold it there while installing first wheel bolt. 
Unscrew the alignment bolt (1) to install the last 
wheel bolt.

Before storing the jack, the jack arm must be 
lowered almost to the base of the jack. 
Store the spare wheel first and then the vehicle jack.
14. Using the wrench, tighten the five bolts evenly, 
following the sequence illustrated, until all bolts are 
tight.
Observe a tightening torque of 80 ft.lb. (110 Nm). 
15. Ensure proper tire pressure.
16. Depress wheel change switch for level control. The 
indicator lamp in the switch and the ADS 
malfunction indicator lamp will go out.
Wa r n i n g !
Always replace wheel bolts that are damaged or 
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired 
immediately.Incorrect mounting bolts or improperly tightened 
mounting bolts can cause the wheel to come off. 
This could cause an accident. Be sure to use the 
correct mounting bolts.
