Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck 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 on page 359.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 97 ft.lb. (130 Nm)
whenever wheels are mounted.
For rim and tire specif ications, refer to technical data on
page 359.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
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.

Te ch n i c a l

cluster displayPractical hintsCar care Index 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.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.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 flanges 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
page 318.

Important!
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle, and is fully functional.
In the case of a flat tire, you may use the spare wheel.
For rim and tire specifications, refer to “Technical data”
on page 359.
Note:
Repair or replace damaged tire at your earliest
convenience.
To gain access to spare wheel, remove spare wheel
cover, see page 312.
Remove nuts (1) and take spare wheel off the spare
wheel carrier.
Place the punctured wheel on the spare wheel carrier,
secure it with the nuts (1) and cover it with the spare
wheel cover.
Note:
For safety reasons check regularly that the spare wheel
is securely fastened.

vehi c le a t the j ack take-up b ra ckets b ui lt i nto eit her
side of the vehicle. To help avoid personal injury,
use the jack only to lift the vehicle during a wheel
change. Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet away
from the area under the lifted vehicle. Always
firmly set parking brake and block wheels before
raising vehicle with jack.Do n ot d is engage parki n g brake w hil e t he vehi c le i s

end is fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.
