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.

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.

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)
K up to 68 mph (110 km/h)
L up to 74 mph (120 km/h)
M up to 80 mph (130 km/h)
N up to 87 mph (140 km/h)
P up to 93 mph (150 km/h)
Q up to 100 mph (160 km/h)
R up to 106 mph (170 km/h)

Vehicle Capacity Weight
Rated cargo and luggage load plus 68 kilograms (150
lbs) times the vehicle’s designated seating capacity.
Vehicle Maximum Load on the Tire
Load on an individual tire that is determined by
distributing to each axle its share of the maximum
loaded vehicle weight and dividing it by two.
Rotating Tires
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off
Road type tires. Rotation will increase tread life, help tomaintain mud, snow, and wet traction levels, and
contribute to a smooth, quiet ride.
If applicable to your vehicle's tire configuration, tires
can be rotated according to the tire manufacturer’s
recommended intervals in the tire manufacturer’s
warranty pamphlet located in your vehicle literature
portfolio. If none is available, tires should be rotated
every 10000 miles (16000 km), or sooner if necessary,
according to the degree of tire wear.
The same rotation (spinning) direction must be
maintained when fitted, see "Direction of Rotation".
Rotate tires before the characteristic tire wear pattern
becomes visible (shoulder wear on front tires and
treadcenter wear on rear tires).
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
Thoroughly clean the mounting face of wheels and
brake disks, i.e. the inner side of the wheels/tires,
during each rotation. Check for and ensure proper tire
inflation pressure, refer to "Recommended Tire
Inflation Pressure".
WARNING!
Rotate front and rear wheels only if the tires are of
the same dimension.

Rotation pattern for single and dual rear wheels
Single Rear Wheels:
Rotate the tires by axle. Never change the direction
of rotation of your tires. Make sure that on one axle
just one type of tire (same size, type construction,
load and speed rating) is used.
Dual Rear Wheels:
Rotate front tires by axle and the outer rear tire side
to side if there is no approved direction of rotation.
The tires used on dual wheel assemblies should be
WARNING!
In order to avoid loosing a wheel and in order to re-
duce the risk of fatal or serious injuries or vehicle
damage, please follow these safety instructions:
Always replace wheel bolts that are damaged or
rusted.
Never apply oil or grease to wheel bolts.
If a wheel hub thread is damaged, you must not
drive the vehicle. Consult a qualified specialist
workshop.
Only use genuine wheel bolts approved from the
vehicle manufacturer and specified for your
vehicle’s rims. Check tightness of wheel bolts or
nuts regularly and retighten with a torque wrench,
if necessary. Tighten wheel bolts or nuts in a cross-
pattern sequence. After changing a wheel, the
wheel bolts or nuts must be tightened once the
vehicle has been driven for about 30 miles (50 km).
If new or repainted wheels are fitted, the wheel
bolts or nuts must be retightened again after about
600 to 3000 miles (about 1000 to 5000 km).
