Potential problems associated with
underinflated and overinflated tiresProper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. The following three primary
areas are affected by improper tire infla-
tion pressure:

1. Safety 2. Economy
Improper inflation pressures can cause
uneven wear patterns to develop across
the tire tread. These abnormal wear pat-
terns will reduce tread life resulting in a
need for earlier tire replacement. Under-
inflation also increases tire rolling resis-
tance and results in higher fuel
consumption.
Warning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly, ad-
versely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road de-
bris, potholes etc.
Warning
G
Improperly inflated tires are dangerous
and can cause accidents.
Unequal tire inflation pressures can
cause steering problems. You could lose
control of your vehicle.
Unequal tire inflation pressures from one
side of the vehicle to the other can cause
the vehicle to drift to the right or left. Al-
ways drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

3. Ride comfort and vehicle stabilityProper tire inflation contributes to a
comfortable ride. Overinflation produces
a jarring and uncomfortable ride.
Besides the tire name (sales designa-
tion) and manufacturer's name, a num-
ber of markings can be found on a tire.
Below are some explanations regarding
the markings on your vehicle’s tires:

Warning
G
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. Overloading the tires can also
result in handling or steering problems, or
brake failure.Never overload them.The vehicle maximum load on the tire
must not exceed the load carrying capac-
ity of the tire on your vehicle.

You will not exceed the tire’s load carrying

Never exceed the maximum tire inflation
pressure. Follow recommended tire infla-

tires wear excessively and/or unevenly,
adversely affect handling and fuel econo-

Do not overinflate tires. Overinflated tires
can adversely affect handling and ride

Air pressureThe amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.Aspect ratioDimensional relationship between the
tire section height and the section width
expressed in percentage.
BarAnother metric unit for air pressure.
There are 14.5038 pounds per square

wrapped by steel cords that hold the tire
onto the rim.Cold tire inflation pressureTire inflation pressure when your vehicle
has been sitting for at least 3 hours or

Rotate tires before the characteristic
tire wear pattern becomes visible (shoul-
der wear on front tires and tread center
wear on rear tires).
The reasons for any rapid or unusual
wear should be corrected prior to rota-
tion being performed.
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner
side of the wheels/tires, during each ro-
tation. Check for and ensure proper tire infla-
tion pressure, refer to "Recommended
tire inflation pressure" (
\2
page 361).
!
CAUTION
If your vehicle is equipped with the
tire pressure monitor*, each wheel
has an electronic component.
Tire mounting tools should not be ap-
plied in the area of the valve, as this
could damage the electronic compo-
nents.
Have the tires changed only at an
authorized Sprinter Dealer.
Warning
G
In order to avoid loosing a wheel and in or-
der to reduce the risk of fatal or serious
injuries or vehicle damage, please follow
these safety instructions:Always replace wheel bolts that are dam-
aged or rusted.Never apply oil or grease to wheel bolts.

Winter driving
4
For safe handling, make sure all winter
tires mounted are of the same make and
have the same tread design.
Always observe the speed rating of the
winter tires installed on your vehicle. If
the maximum speed for which your tires
are rated is below the speed rating of
your vehicle, you must 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.
\1
Reactivate the tire pressure monitor.
While studded tires improve perfor-
mance on ice, skid and traction capabil-
ity on wet or dry surfaces may be poorer
than that of non-studded tires. Some
states prohibit studded tires; therefore,
local laws should be checked before us-
ing these tire types.
Warning
G
Winter tires with a tread depth under
1/6 in (4 mm) must be replaced. They are
no longer suitable for winter operation.
Warning
G
If you use your spare tire when winter
tires are fitted on the other wheels, be
aware that the difference in tire charac-
teristics may impair turning stability and
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized Sprinter
Dealer.
