2014 MERCEDES-BENZ SPRINTER tire pressure

DOT (Department of Transportation)
DOT marked tires fulfill the requirements of
the United States Department of Transporta-
tion.
Average weight of vehicle occupants
The number of occupants for which the vehi-
cle is designed multiplied by 68 kilograms
(150 lbs).
Uniform Tire Quality Grading Standards
A uniform standard to grade the quality of
tires with regard to tread quality, traction and
temperature characteristics. The quality
grading assessment is made by the manufac-
turer following specifications from the U.S
government. The quality grade of a tire is
imprinted on the sidewall of the tire.
Recommended tire pressure
The recommended tire pressure are the pres-
sures specified for the tires mounted on the
vehicle at the factory.
The Tire and Loading Information placard 7
contains the recommended tire pressure for
cold tires, the maximum permissible load and
the maximum permissible vehicle speed.
The tire pressure table contains the recom-
mended tire pressure for cold tires under var-
ious operating conditions, i.e. loading and/or
speed of the vehicle.
Increased vehicle weight due to optional
equipment
The combined weight of all standard and
optional equipment available for the vehicle,
regardless of whether it is actually installed
on the vehicle or not.
Wheel rim
The part of the wheel on which the tire is
mounted.
GAWR (Gross Axle Weight Rating)
GAWR is the maximum gross axle weight rat-
ing. The actual load on an axle must never
exceed the gross axle weight rating. The Gross Axle Weight Rating can be found on the
vehicle identification plate on the driver seat
frame (Y
page 319).
Speed index
The speed index is part of the tire identifica-
tion. It specifies the speed range for which the
tire is approved.
GTW (Gross Trailer Weight)
GTW is the total of weight of a trailer and the
weight of the load, accessories etc. on the
trailer.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, spare
wheel, accessories installed, occupants, lug-
gage and the drawbar noseweight if applica-
ble. The gross vehicle weight may never
exceed the gross vehicle weight rating
(GVWR) specified on the vehicle identification
plate at the base of the driver's seat
(Y page 319).
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permitted gross
weight of the fully laden vehicle (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 driver seat frame (Y page 319).
Maximum weight of the laden vehicle
The 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 are the
equivalent of 1 psi. Another tire pressure unit

is bar. 100 kilopascals (kPa) are the equiva-
lent of 1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of
the tire more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum filling capacity
of fuel, oil, and coolant. It also includes the
air-conditioning system and optional equip-
ment if these are installed on the vehicle, but
does not include passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or
pounds is the maximum weight for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pres-
sure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's sur-
face. Tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
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 for at least
three hours without direct sunlight on the
tires, and
R if the vehicle has not been driven further
than 1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact
with the road.
Tire 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
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the accesso-
ries.
TIN (Tire Identification Number)
A unique identification number which can be
used by a tire manufacturer to identify tires,
for example for a product recall, and thus
identify the purchasers. The TIN is composed
of the manufacturer identification code, tire
size, tire model code and manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire. 306
What you should know about wheels and tiresWheels and tires

Traction
Traction is the result of friction between the
tires and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread is
level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over
designated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Flat tire
General notes
Your vehicle is equipped with a spare wheel.
The spare wheel is under the vehicle at the
rear (Y page 313).
Information about fitting a wheel can be found
in the "Wheel change" section (Y page 308).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 292). Changing wheels
Rotating the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec-
tronic components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 308).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated
every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and reac-
tivate the tire pressure monitor if necessary. Changing wheels

General notes
! Retreaded tires are neither tested nor rec-
ommended for Sprinter vehicles, since pre-
vious damage cannot always be detected
on retreaded tires. We can therefore not
guarantee driving safety. Do not mount
used tires if you have no information about
their previous usage. The recommended tire pressures can be
found:
R
on the Tire and Loading Information plac-
ard 8
on the B-pillar on the driver's side
R on the tire pressure table on the B-pillar on
the driver's side
The recommended tire pressure can also be
found in the "Tire pressure table" section in
these Operating Instructions (Y page 297).
The wheel/tire combination for your vehicle
can be found on the tire pressure table. Fur-
ther information on wheel/tire combination
can be obtained at any qualified specialist
workshop.
Check tire pressures regularly and only when
the tires are cold. Observe the notes on the
recommended tire pressures (Y page 290).
Follow the maintenance recommendations in
the tire manufacturer's warranty book in your
vehicle documents.
Notes on the vehicle equipment – always
install the vehicle:

WARNING
Wheel and tire dimensions as well as the type
of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may
be severely affected. There is a risk of an acci-
dent.
In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
