Tires and wheels
See an authorized Mercedes-Benz Center
for information on tested and recommend-
ed rims and tires for summer and winter
operation. They can also offer advice con-
cerning 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 and
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 of less than
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 Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:

The wheel brakes or suspension compo-
nents can be damaged


The correct operating clearance of the
wheels and the tires are no longer guar-
anteed
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 re-
sult 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.

363 Operation
Tires and wheels
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 336).
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 432) and
(
page 452).Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use Genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

433 Practical hints
Where will I find ...?
In case of a flat tire, you may temporarily
use the spare wheel when observing the
following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km / h).


Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.


Do not operate vehicle with more than
one spare wheel mounted.
For more information, see “Spare wheel”
(
page 487).

454 Practical hintsFlat tire
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.
1Jack take-up bracket
2Jack

Place jack2 on firm ground.

Position jack2 under take-up
bracket1 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.

Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while
vehicle is raised.Warning!
G
Position the jack only on the jack take-up
brackets designed for this purpose.
If the jack is not properly positioned, the ve-
hicle may slip off of the jack.

Removing the wheel
1Alignment bolt
Unscrew upper-most wheel bolt and re-
move.

Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.

Remove the remaining bolts.

Remove the wheel.Mounting the spare wheel

Clean contact surfaces of wheel and
wheel hub.

Guide the spare wheel onto the align-
ment bolt and push it on.
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 bolt and wheel hub
threads.
!
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 dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz 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. Be
sure to use the correct wheel bolts.


456 Practical hintsFlat tire
Insert wheel bolts and tighten them
slightly.

Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Vehicles with collapsible tire
(E 63 AMG only):

Continue the procedure by following
the instructions under “Inflating the
collapsible tire” (
page 456) and then
“Lowering the vehicle” (
page 458).
Vehicles with Minispare wheel
(except E 63 AMG):

Continue the procedure by following
the instructions under “Lowering the
vehicle” (
page 458).Inflating the collapsible tire
(E 63 AMG only)

Take the electric air pump out of the
trunk (
page 432).
Warning!
G
Only use Genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
fall off the jack.
Warning!
G
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
air pump before
lowering the vehicle.
Warning!
G
Observe instructions on air pump label.!
Do not lower the vehicle before inflating the
collapsible tire. Otherwise the rim may be dam-
aged.


458 Practical hintsFlat tire
Store the electrical plug 3 and the air
hose 4 behind the flap 1 and place
the electric air pump back in the desig-
nated storage space underneath the
trunk floor (
page 432).
Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
1-5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).
Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position).

Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor
(page 432).
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).
i
Wrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the trunk.
You can also place the damaged wheel down into
the spare wheel well. In this case, you must stow
the holder from the spare wheel well in the trunk.
Vehicles with Advanced TPMS* (Canada only):
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
