Tires and wheels
See an 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.
Important guidelines

Only use sets of tires and rims of the
same type and make.


Tires must be of the correct size for the
rim.


Break in new tires for approximately
60 miles (100 km) at moderate
speeds.


Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss or
damage to the tire beads.


If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.


Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).


When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!
G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See an authorized
Mercedes-Benz Light Truck Center for fur-
ther information. If incorrectly sized rims
and tires are mounted:

The wheel brakes or suspension
components can be damaged.


The operating clearance of the wheels
and the tires may no longer be correct.
Warning!
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, only use 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.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.

398 OperationTires and wheelsIn some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.
If applicable to your vehicle’s tire configu-
ration, tires can be rotated according to
the tire manufacturer’s recommended in-
tervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 3 000 to 6 000 miles
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear.
The same rotation (spinning) direction
must be maintained (
page 368).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.For information on wheel change, see the
“Practical hints” section (
page 469) and
(
page 497).Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 lb-ft (150 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

Preparing the vehicle
Prepare the vehicle as described
(page 497).Vehicles with Minispare wheel:

Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(page 469).

Take the Minispare wheel out of the
cargo compartment (

Vehicles with collapsible tire
(ML 63 AMG only):

Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the cargo compartment
(page 474).Lifting the vehicle
i
Vehicles with collapsible tire:
You can use the power outlet in the cargo com-
partment or in the front of the rear seats to oper-
ate the electric air pump even when the ignition
is switched off, e.g. in order to inflate the col-
lapsible emergency spare tire.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.
!
Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for
scissors-type jack.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides 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 not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure that the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.


499 Practical hints
Flat tire

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One collapsible wheel chock is includ-
ed with the vehicle tool kit
(page 469). For information on set-
ting up the collapsible wheel chock,
see (page 472).
When changing wheel on a level surface:

Place one wheel chock in front of and
another sizeable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
hill, place the wheel chock and another
sizeable object as follows:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the axle not
being worked on.1Wheel wrench

On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench1).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.2Take-up bracket

500 Practical hintsFlat tire
Position jack3 under the take-up
bracket2 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an in-
cline.

Turn crank4 clockwise until jack3
is fully seated in take-up bracket2
and the jack base evenly meets the
ground.

Continue to turn crank4 until the
wheel is a maximum of 1.2 in (3 cm)
from the ground.Removing the wheel
1Alignment bolt

Unscrew upper-most wheel bolt and
remove it.

Replace this wheel bolt with alignment
bolt1 supplied with the tool kit
(page 469).

Remove the remaining bolts.

Remove the wheel.
Warning!
G
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle.

Never start the engine when the vehicle
is raised.


Never lie down under the raised vehicle.
!
Do not place wheel bolts in sand or dirt. This
could result in damage to the bolts and wheel
hub threads.

alloy wheels and collapsible tire (AMG
vehicles)
2Wheel bolt for 17" light alloy wheels or
Minispare wheel (located in vehicle tool
kit (
page 469))

Clean contact surfaces of wheel and
wheel hub.

Guide spare wheel onto the alignment
bolt and push it on the wheel hub.

Insert wheel bolts and tighten them
slightly.

Unscrew the alignment bolt.

Insert the remaining wheel bolt and
tighten it slightly.
!
Wheel bolts2 must be used when mount-
ing 17" light alloy rims or the Minispare wheel.
The use of any wheel bolts other than wheel
bolts2 for 17" light alloy rims or the Minispare
wheel will damage the vehicle’s brakes.
!
To avoid paint damage, place wheel flat
against hub and hold it there while installing first
wheel bolt.
Warning!
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. Do not continue to
drive under these circumstances! Contact
an authorized Mercedes-Benz Light Truck
Center or call Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident.
Make sure to use the correct wheel bolts.
