2017 MERCEDES-BENZ SLC spare tire

Speed rating The speed rating is part of the tire identification.
It specifies the speed range for which the tire is
approved.
GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of
the vehicle including fuel, tools, the spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight, if applicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight rating GVWR as specified on the vehi-
cle identification plate on the B-pillar on the
driver's side.
GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross
weight of af ully loaded vehicle (the weight of the
vehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight, if
applicable). The gross vehicle weight rating is
specified on the vehicle identification plate on
the B-pillar on the driver's side.
Maximu ml oaded vehicle weightThe maximum weight is the sum of: R
the curb weight of the vehicle R
the weight of the accessories R
the load limit R
the weight of the factory installed optional
equipment
Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1p si. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewal lo f
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of av ehicle with standard equipment
including the maximum capacity of fuel, oil and
coolant. It also includes the air-conditioning sys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage. Maximu ml oad ratingThe maximum load rating is the maximum per-
missible weight in kilograms or lbs for which a
tire is approved.
Maximu mp ermissible tire pressureMaximum permissible tire pressure for one tire.
Maximu ml oad on one tireMaximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.
PSI (pounds per squar ei nch)As tandard unit of measure for tire pressure.
Aspect ratio Relationship between tire height and tire width
in percent.
Tire pressure This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and R
if the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.All about wheel sa nd tires 273

These tires have been specially adapted for
use with the control systems, such as ABS or
ESP ®
,a nd are marked as follows:R
MO = M ercedes-Benz OriginalR
MOE = M ercedes-Benz Original Extended
(tires featuring run-flat characteristics) R
MO1 = M ercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with al oad, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .T his
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age 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 quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz ,s ince previ-
ous damage cannot alway sbed etected on
retreaded tires. As ar esult, 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.
The recommended pressures for various oper-
ating conditions can be found: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
( Y
page 258).
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. Notes on the vehicle equipment –a lway se quip
the vehicle: R
with tires of the same size on ag iven axle (left
and right) R
with the same type of tires at ag iven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to install ad iffer-
ent type or make in the event of af lat tire.
Observe t he
"MOExtended tires (tires with
run-flat characteristics" section ( Y
page 242).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefor er ecommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit may be obtained from
aq ualified specialist workshop.

Important safety notes
G WARNING
The wheel or tire size as well as the tire type of
the spare wheel or emergenc ys pare wheel
and the wheel to be replaced may differ.
Mountin gane mergenc ys pare wheel may
severely impair the driving characteristics.
There is ar isk 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
emergenc ys pare wheel that differs in size. R
only use as pare wheel or emergenc ys pare
wheel of ad ifferent size briefly. R
do not switch ESP ®
off.R
have as pare wheel or emergenc ys pare
wheel of ad ifferent 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 emergenc ys pare wheel or spare
wheel of ad ifferent size, you must not exceed
the maximum speed of 50 mph (80 km/h).Emergency spar ew heel 279

Mercedes-Benz Center.
You shoul dr egularl yc heck the pressure of the
emergency spare wheel ,p ar ticularly prior to
long trips, and correct the pressure as neces-
sary ( Y
page 258). The value on the wheel is
valid.
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe
the time restriction on us easw el last he speed
limitation specified on the emergency spare
wheel.
Replace the tire sa fte rs ix years at the latest,
regardless of wear. Thi sa ls oa pplies to the
emergency spare wheel.
Whe ny ou are driving with the collapsibl es pare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor canno tf unc-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defectiv ew he el ha sb ee nr eplaced with a
new wheel.
Vehicles with tire pressure monitor: after
mounting an emergency spare wheel ,t he sys-
tem may stil ld is play the tire pressure of the
removed wheel for af ew minutes. The value dis-
played for the mounted emergency spare wheel
is not the same as the current tire pressure of
the emergency spare wheel.
