Wheels and tires
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
wheel.
!On vehicles equipped withatire pressure
monitor, electronic componentsa re located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aqualified spe-

RAlloy wheel 133 lb-ft(180 Nm)
XTurn the jack back to its out-of-use position.
XStow the jack and the rest of the tire-change
tool kit in the vehicle again.
XWheel with hub cap: position the opening for
the tire valve in the hub cap over the tire valve.
XPush the edge of the hub cap with both hands
against the wheel until it clicks into place.
Make sure the hub cap retaining catches
engage on the steel wheel.
XIf included in the vehicle equipment, secure
the faulty wheel in the spare wheel bracket
(
Ypage 292). Otherwise, transport the faulty
wheel in the cargo compartment.
XCheck the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 270).
Vehicles with the tire pressure monitor sys-
tem: all mounted wheels must be equipped
with functionings ensors.

Wheel and tirec ombination
General notes
!
Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-
ous damage cannot alwaysbed etected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if you have no information about their previous
usage.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and
accessories which have been specially
approved by Mercedes-Benz for your vehicle.
These tires have been specially adapted for
use with the driving safety systems, such as
ABS or ESP
®.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with aload, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components. This
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz acceptsnol iability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Further information on wheels, tires and
approved combinations can be obtained from
any qualified specialist workshop.
!Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and the
risk of damage to the wheels and tires as a
result of driving over obstacles increases.
You will find atable with the recommended tire
pressures for various vehicle loads on the inside
of your vehicle's fuel filler flap or under "Tire
pressure tables" (
Ypage 278). You can find fur- ther information under "Tire pressure"
(
Ypage 270).
Check tire pressures regularly and only when
the tires are cold.
Notes on the vehicle equipment –alwayse quip

Rwith tires of the same size across an axle
(left/right)
Rwith the same type of tires on all wheels at a
given time (summer tires, winter tires)
iNot all wheel/tire combinations can be
installed at the factory in all coun tries.
