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. Rims 
and tires must be of the correct 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 
fastened to a tightening torq ue of 110 ft.lb. (150 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Wa r n i n g !
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.

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 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.
Notes:
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 tire beads. For this reason, check rims for 
damage at regular intervals. The rim f langes must be 
checked for wear before a tire is mounted. Remove 
burrs, if any.
Check and ensure proper tire inflation pressure after 
rotating the wheels. For tire inflation pressure see 
inside of fuel filler flap and also page 345.Spare wheel
Spare wheel CL 500 and CL 600 
(except Sport Package)
Important!
The spare wheel rim is mounted with a full size tire of 
the same type as on the vehicle, and is fully functional. 
However, that spare wheel rim is weight optimized and 
has a limited service life of 12 000 miles (20 000 km) 
use before a standard wheel rim must replace it.
In the case of a flat tire, you may temporarily use the 
spare wheel.
Do not operate vehicle with more than one spare wheel 
mounted.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use 
for over a total of 12 000 miles (20 000 km) 
(aggregate of all uses) may cause wheel rim failure 
leading to an accident and possible injuries.
