collapsible spare wheel, see (Y page 363).
i Vehicles with tire pressure monitor: all
wheels mounted must be equipped with
functioning sensors. Wheel and tire combinations
General notes
! For safety reasons, Mercedes-Benz
recommends that you only use tires and
wheels which have been approved by
Mercedes-Benz specifically for your
vehicle. These tires have been specially adapted for
use with the control systems, such as ABS
or ESP
®
, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only
certain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicle noise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, 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 vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
! Retreaded tires are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be
detected on retreaded tires. As a result,
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.
i The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information
placard with the recommended tire
pressures on the B-pillar on the driver's
side
R in the tire pressure table on the inside of
the fuel filler flap Wheel and tire combinations
359Wheels and tires Z

Observe the notes on recommended tire
pressures under various operating
conditions (Y page 334).
Check tire pressures regularly, and only
when the tires are cold. Comply with the
maintenance recommendations of the tire
manufacturer in the vehicle document
wallet.
i Notes on the vehicle equipment – always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
i On the following pages, you can find
information on approved wheel rims and
tire sizes for equipping your vehicle with
winter tires. Winter tires are not available
at the factory as standard equipment or
optional extras.
If you would like to equip your vehicle with
approved winter tires, you may also, in
certain circumstances, require rims of the
appropriate size. The size of the approved
winter tires may deviate from that of the
standard tires. This is dependent on the
model and the equipment installed at the
factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
i Overview of abbreviations used in the
following tire tables:
R BA: both axles
R FA: front axle
R RA: rear axle
In the following table, the wheel/tire
combinations are assigned to the vehicle
models through variants, e.g. V1, V2 etc.: V1 GLK 250 BlueTEC, GLK 350, GLK 350
4MATIC i
Not all wheel and tire combinations are
available at the factory for all countries. 360

Emergency spare wheel
Important safety notes
G
WARNING
The wheel or tire size as well as the tire type
of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
R
adapt your driving style accordingly and
drive carefully.
R never mount more than one spare wheel or
emergency spare wheel that differs in size.
17 USA: not for GLK 250 BlueTEC.
18 Use of snow chains is not permitted. Observe the notes in the "Snow chains" section.
19 MOExtended tires (tires featuring run-flat characteristics) only in combination with an activated tire pressure
loss warning system. Emergency spare wheel
361Wheels and tires
Z

R
only use a spare wheel or emergency spare
wheel of a different size briefly.
R do not switch ESP ®
off.
R have a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/h).
Snow chains must not be mounted on
emergency spare wheels. General notes
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as
necessary (Y page 334). The applicable value
is found on the wheel or under "Technical
data" ( Ypage 359).
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor:
after mounting an emergency spare wheel,
the system may still display the tire
pressure of the removed wheel for a few
minutes. The value displayed for the
mounted emergency spare wheel is not the
same as the current tire pressure of the
emergency spare wheel.
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the
emergency spare wheel. Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel. Collapsible spare wheel
