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 tires should be replaced in sets. Rims and tires 
must be of the correct size and type. For dimensions, 
see “Technical Data” (page 314).
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, refer to “Technical Data” 
(page 314).
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.

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.
Unidirectional tires must always be mounted with arrow 
on tire sidewall pointing in direction of vehicle forward 
movement.
If the arrow on tire side wall does not point in direction 
of vehicle forward movement when using the spare
