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 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.

Important!
The spare wheel rim size is 7
1/2J x 17 H 2.
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle’s front axle, 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.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restriction:
•Drive to the nearest tire repair facility as soon as
possible.
In the case of a rear axle f lat tire, you may temporarily
use the spare wheel, when observing the following
restrictions:
•Do not exceed vehicle speed of 50 mph (80 km/h)
•Drive to the nearest tire repair facility to have the
flat tire repaired or replaced as appropriate.Do not operate vehicle with more than one spare wheel
mounted.
Unid irectional tires must a lways be mou nted w it h a rrow
on tire sidewall pointing in direction of vehicle forward
movement.
For rim and tire specifications, refer to “Technical Data”
(page 314).
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.The dimensions of the spare wheel are different
from those of the road wheels for the rear axle. As a
result, the vehicle handling characteristics change
when driving with a spare wheel mounted on the
rear axle.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.
