186 STARTING AND OPERATING
Recommended Tire Inflation Pressure
The tire inflation pressure (including the spare wheel)
should be checked regularly and adjusted as well asinspecting for signs of tire wear or visible damage. Use
a good quality pocket-type gauge to check tire inflation
pressure.
Do not make a visual judgement when determining
proper inflation. Radial tires may look properly
inflated even when they are underinflated.
The tire inflation pressure should be checked
regularly, i.e. at least each time you refuel the vehicle,
and should only be adjusted on cold tires. The
preferred interval for checking the tire inflation
pressure, however, is before each trip.
The tires can be considered cold if the vehicle has been
parked for at least 3 hours or driven less than 1 mile
(1.6 km) at an ambient temperature of approximately
68 °F (20 °C).
Follow recommended cold tire inflation pressures
listed on Tire and Loading Information placard on the
driver’s door B-pillar.
Keeping the tires properly inflated provides the best
handling, tread life and riding comfort.
The pressure difference between the tires on a single
axle should not exceed 1.5 psi (10 kPa).
WARNING!
Avoid spinning of one drive wheel. This may
cause serious damage to the drivetrain which is
not covered by the Warranty.
WARNING!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result
in sudden deflation (blowout) because they are
more likely to become punctured or damaged by
road debris, potholes etc.

Tire Inflation Pressure".
1 Recommended cold tire inflation pressures
NOTE: Data shown on placard are for illustration
purposes only. Tire data are specific to each vehicle
and may vary from data shown in the illustration.
Refer to placard on vehicle for actual data specific to
your vehicle.The Tire and Loading Information placard on the
driver’s door B-pillar lists the recommended cold tire
inflation pressures for all load conditions up to the
maximum permissible weight limits (GAWR). The tire
inflation pressures listed apply to the tires installed as
original equipment.
Important Notes on Tire Inflation Pressure
Tire temperature and tire inflation pressure are also
increased while driving, depending on the driving
speed and the tire load.
Tire inflation pressure changes by approximately 1.5
psi (10 kPa) per 18 °F (10 °C) of air temperature change.
WARNING!
If the tire inflation pressure drops repeatedly:
 Check the tires for punctures from foreign
objects.
 Check to see whether air is leaking from the
valves or from around the rim.

188 STARTING AND OPERATING
Keep this in mind when checking tire inflation
pressure where the temperature is different from the
outside temperature.
For example:
If inside temperature is 68 °F (20 °C) and the outside
temperature is 32 °F (0 °C) then the cold tire inflation
pressure should be increased by 3 psi (0.2 bar), which
equals 1.5 psi (0.1 bar) for every 18 °F (10 °C) for this
outside temperature condition.
Check tire pressures more often if subject to a wide
range of outdoor temperatures, as tire pressures vary
with temperature changes.Checking Tire Inflation Pressure
The tire inflation pressure should be checked
regularly, i.e. at least each time you refuel the vehicle.
The preferred interval for checking the tire inflation
pressure, however, is before each trip.
Inflation pressures specified on the Tire and Loading
Information placard on the driver’s door B-pillar are
always cold tire inflation pressures. Check and adjust
the tire inflation pressure when the tires are cold. Cold
tire inflation pressure is defined as the tire pressure
after the vehicle has been parked for at least 3 hours or
driven less than 1 mile (1.6 km) at an ambient
temperature of approximately 68 °F (20 °C).
The cold tire inflation pressure must not exceed the
maximum tire inflation pressure molded into the tire
side wall, refer to "Tire Labeling".
If you check the tire inflation pressure when the tires
are warm (the vehicle has been driven for several miles
or sitting less than 3 hours), the reading will be higher
than the cold reading. This is normal. Do not let air out
to match the specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
WARNING!
Tire pressure may increase during operation.
Never reduce this normal pressure build up or
your tire pressure will be too low.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from being
overheated.

Follow the steps below to achieve correct tire inflation
pressure:
 Remove the cap from the valve on one tire. Firmly press a tire gauge onto the valve.
 Read tire inflation pressure on tire gauge and check
against the recommended tire inflation pressure on
the Tire and Loading Information placard on the
driver’s door B-pillar. If necessary, add air to
achieve the recommended tire inflation pressure.
NOTE: If you have overfilled the tire, release tire
inflation pressure by pushing the metal stem of the
valve with e.g. a tip of a pen. Then recheck the tire
inflation pressure with the tire gauge.
 Install the valve cap.
 Repeat this procedure for each tire.
WARNING!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result
in sudden deflation (blowout) because they are
more likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire and
Loading Information placard on the driver’s door
B-pillar. Overloading the tires can overheat them,
possibly causing a blowout.
WARNING!
After inspecting or adjusting the tire inflation
pressure always reinstall the valve cap if
equipped.
This will prevent moisture and dirt from entering
the valve stem, which could damage the valve
stem.

190 STARTING AND OPERATING
Potential Problems associated with Underinflated
and Overinflated Tires
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire inflation pressure:
1. Safety
WARNING!
Improperly inflated tires are dangerous and can
cause accidents.
 Underinflation increases tire flexing and can
result in tire failure.
 Overinflation reduces a tire’s ability to
cushionshock. Objects on the road and chuck
holes can cause damage that results in tire
failure.
 Unequal tire inflation pressures can cause
steering problems.You could lose control of
your vehicle.
 Overinflated or underinflated tires can
affectvehicle handling and can fail suddenly,
resulting in loss of vehicle control.
 Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to drift
to the right or left. Always drive with each tire
inflated to the recommended cold tire inflation
pressure.

STARTING AND OPERATING 191

2. Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These
abnormal wear patterns will reduce tread life resulting
in a need for earlier tire replacement. Underinflation
also increases tire rolling resistance and results in
higher fuel consumption.
3. Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable
ride.Tire Labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings can be
found on a tire.
NOTE: Data shown on tire are for illustration purposes
only. Actual data on tires are specific to each vehicle
and may vary from data shown in the illustration.
(1) DOT, Tire Identification Number (TIN)
(2) Maximum tire load

194 STARTING AND OPERATING
For example, a load rating of 115 corresponds to a
maximum load of 2680 lbs (1215 kg) the tire is designed
to support.
If two values are given (as illustrated), the first value,
preceding the slash "/", applies to single tires (rear
axle).
The second value, succeeding the slash "/", applies to
twin tires (dual wheel rear axle).
The commercial vehicle tires based on European
standards may have an additional value in the
parentheses (as illustrated). In such case, the value
preceding the parentheses is valid for European
countries and the parenthesized for the USA and
Canada.
Refer also to "Maximum Tire Load" where the
maximum load associated with the load index is
indicated in kilograms and lbs.
NOTE: Tire load rating (6) and tire speed rating (7) are
also referred to as "service description".
WARNING!
The tire load rating must always be at least half of
the GAWR of your vehicle. Otherwise, tire failure
may be the result which may cause an accident
and/or serious personal injury to you or others.
For information on GAWR, refer to "Tire and
Loading Terminology".
Always replace rims and tires with the same
designation, manufacturer and type as shown on
the original part.
WARNING!
Do not overload the tires by exceeding the specified
load limit as indicated on the Tire and Loading Infor-
mation placard on the driver’s door B-pillar.
Overloading the tires can overheat them, possibly
causing a blowout.
Overloading the tires can also result in handling
or steering problems, or brake failure.

Tire Speed Rating
The tire speed rating (7) indicates the approved
maximum speed for the tire.
The commercial vehicle tires based on European
standards may have an additional index in the
parentheses (as illustrated). In such case, the index
preceding the parentheses is valid for European
countries and the parenthesized for the USA and
Canada.
NOTE: Always observe the speed rating of the winter
tires installed on your Sprinter vehicle. If the
maximum speed for which your tires are rated is belowthe speed rating of your Sprinter vehicle, youmust
place a notice to this effect where it will be seen by the
driver.
Such notices are available at your tire dealer or any
authorized Sprinter Dealer.
NOTE: Tire load rating (6) and tire speed rating (7) are
also referred to as "service description".
WARNING!
Even when permitted by law, never operate a vehicle at
speeds greater than the maximum speed rating
of the
tires.
Exceeding the maximum speed for which tires are
rated can lead to sudden tire failure, causing loss
of vehicle control and possibly resulting in an
accident and/or personal injury and possible
death, for you and for others.
Index Speed Rating
F up to 50 mph (80 km/h)
G up to 56 mph (90 km/h)
J up to 62 mph (100 km/h)

DOT, Tire Identification Number (TIN)
(1) DOT
(2) Manufacturer’s identification mark
(3) Tiresize
(4) Tire type code (at the option of the tire
manufacturer)
(5) Date of manufacture NOTE: Data shown on tire are for illustration purposes
only. Actual data on tires are specific to each vehicle
and may vary from data shown in the illustration.
U.S. tire regulations require each new
tiremanufacturer or tire retreader to mold a TIN into or
onto a sidewall of each tire produced.
The TIN is a unique identifier which facilitates efforts by
tire manufactures to notify purchasers in recall situations
or other safety matters concerning tires and gives
purchasers the means to easily identify such tires.
The TIN is comprised of "Manufacturer’s identification
mark", "Tire size", "Tire type code" and "Date of
manufacture".
The TIN may be found on one or both sides of the tire
however the date code may only be on one side. Tires
with white sidewalls will have the full TIN including
date code located on the white sidewall side of the tire.
Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle.
If the TIN is not found on the outboard side then you
will find it on the inboard side of the tire. In this case,
the tire must be remounted. Make sure the TIN is
