Rims and tires
Rims and tires
!
Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to provide best
possible performance in conjunction with the
driving safety systems on your vehicle such as
ABS or ESP
®. Tires specially developed for
your vehicle and tested and approved by
Mercedes-Benz can be identified by finding the
following on the tire’s sidewall:


MO = M
ercedes-Benz O
riginal equipment
tires
AMG vehicles only:
Does not apply to all approved tires on AMG
vehicles. For information on tested and
approved tires for AMG vehicles, contact an
authorized Mercedes-Benz Center.
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!
Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as


poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
i
Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. A Tire and Loading Information placard
with the recommended tire inflation pressures is
located on the driver’s door B-pillar
(
page 564). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds (
page 570) or for vehi-
cle loads less than the maximum loaded vehicle
condition (
page 577). If such information is
provided, it can be found on the tire inflation
pressure label located on the inside of the fuel
filler flap. The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
i
The following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Appearance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. Contact an authorized
Mercedes-Benz Center for more information.

Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the Minispare wheel rim.
If the tire inflation pressure on the yellow label
on the Minispare wheel rim differs from the val-
ues given in this Operator’s Manual, inflate the
spare wheel tire to the recommended tire infla-
tion pressure given on the yellow label on the
Minispare wheel rim.

Please note that the tire inflation pressure of
the Minispare differs from the tire inflation pres-
sure of the road tires.
