Life of tire
The service life of a tire depends on varying
factors including but not limited to:
\4Driving style
\4Tire inflation pressure
\4Distance drivenTread depth
Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths under
1/8in (3 mm) for summer tires and
1/6in
(4 mm) for winter tires.
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.6 mm), at which point
the tire is considered worn and should be
replaced.
Recommended minimum tire tread depth:
\4Summer tires
1/8in (3 mm)
\4Winter tires
1/6in (4 mm)
You could lose control of the vehicle as a re-
sult, cause an accident and injure yourself
or others.
Avoid driving up against curbs or parking the
vehicle with part of the tire tread surface on
the curb.Warning
G
Tires and spare tire should be replaced after
6 years, regardless of the remaining tread.
Warning
G
Although the applicable federal motor safety
laws consider a tire to be worn when the
Treadwear Indicators (TWI) become visible
at approximately
1/16in (1.6 mm), we rec-
ommend that you do not allow your tires to
wear down to that level. As tread depth ap-
proaches
1/8in (3 mm) for summer tires or
1/6in (4 mm) for winter tires, the adhesion
properties on a wet road are sharply re-
duced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

1Treadwear Indicator (TWI)
The Treadwear Indicator appears as a solid
band across the tread.
Storing tiresCleaning tires
An arrow on the side wall indicates the in-
tended direction of rotation (spinning) of
the tire which means the wheel must be
mounted in the direction of rotation.
If a tire does not have an arrow on the side
wall indicating the direction of rotation, the
wheel can be mounted either way.
!
CAUTION
Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline/diesel.
!
CAUTION
Never use a round nozzle to power
wash tires. The intense jet of water can
result in damage to the tire.
Always replace a damaged tire.
Direction of rotationiThe Tire Identification Number (TIN)
must always be visible on the outboard
side of the tire.
!
CAUTION
Spare wheels may be mounted against
the direction of rotation (spinning) even
with a unidirectional tire for temporary
use only until the regular drive wheel
has been repaired or replaced. Always
observe and follow applicable tempo-
rary use restrictions and speed limita-
tions indicated on the spare wheel.
Have a spare wheel that was mounted
against the direction of rotation re-
placed with a regular road wheel as
soon as possible.

The following labels on the vehicle show
how much weight it may properly carry.
\4Only vehicles with a gross weight ca-
pacity less than 10,000 lbs (4500 kg)
The tire and loading information plac-
ard can be found on the driver’s door B-
pillar. This placard tells you important
information about the number of peo-
ple that can be in the vehicle and the
total weight that can be carried in the
vehicle.
It also contains information on the
proper size and recommended tire in-
flation pressures for the original equip-
ment tires on your vehicle.
\4The certification label can be found be-
low the driver’s seat on an outward fac-
ing position of the mounting pillar
(\2page 373). This label tells you about
the gross weight capacity of your vehi-
cle, called the Gross Vehicle Weight
Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants,
fuel and cargo. The certification label also tells you about the front and rear
axle weight capacity, called the Gross
Axle Weight Rating (GAWR). The GAWR
is the total allowable weight that can be
carried by a single axle (front or rear).
Never exceed the GVWR or GAWR for
either the front axle or rear axle.

Warning
G
Do not overload the tires by exceeding the
specified load limit as indicated on the tire
and loading information placard on the driv-
er’s door B-pillar or on the certification label
below the driver’s seat on the mounting pil-
lar. Overloading the tires can overheat them,
possibly causing a blowout. Overloading the
tires can also result in handling or steering
problems, or brake failure.
Overloading of tires is dangerous. Overload-
ing can cause tire failure, affect vehicle han-
dling, and increase the stopping distance.
Use tires of the recommended load capacity
for the vehicle. Never overload them.
The vehicle maximum load on the tire must
not exceed the load carrying capacity of the
tire on your vehicle. You will not exceed the
tire’s load carrying capacity if you adhere to
the loading conditions, tire size and cold tire
inflation pressures specified on the tire and
loading information placard, tire pressure la-
bel and this section.

less than 10,000 lbs (4500 kg) only.
The tire and loading information placard is
located on the driver’s door B-pillar.Tire and loading information placard1Seating capacity
2Load limit informationSeating capacity
The seating capacity1 gives you impor-
tant information on the number of occu-
pants that can be in the vehicle. Observe
front and rear seating capacity.
Never let more people ride in the vehicle
than there are designated seating posi-
tions and seat belts available. Make sure
that everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.Load limit information
Locate the statement “The combined
weight of occupants and cargo should nev-
er exceed XXX kilograms or XXX lbs.” 2
on the tire and loading information plac-
ard. The combined weight of all occupants,
cargo/luggage and trailer tongue load (if
applicable) should never exceed the
weight referenced in that statement.
Steps for determining correct load limit
For vehicles with a gross weight capacity
less than 10,000 lbs (4500 kg) only.
The following steps have been developed
as required of all manufacturers under Title
49, Code of U.S. Federal Regulations, Part
575 pursuant to the “National Traffic and
Motor Vehicle Safety Act of 1966”.
iThe data shown on this placard is for il-
lustrative purposes only. The load limit
data and seating data are specific to
each vehicle and may vary from the
data shown in the illustration below.
Refer to the placard on your vehicle for
actual data specific to your vehicle.

Step 1
\1Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs.” on
your vehicle’s placard.
Step 2
\1Determine the combined weight of the
driver and passengers that will be
riding in your vehicle.
Step 3
\1Subtract the combined weight of the
driver and passengers from
XXX kilograms or XXX lbs.Step 4
\1The resulting figure equals the avail-
able amount of cargo and luggage load
capacity. For example, if the “XXX”
amount equals 1400 lbs and there will
be five 150 lbs passengers in your vehi-
cle, the amount of available cargo and
luggage load capacity is 650 lbs (1400-
750 (5 x150) = 650 lbs).
Step 5
\1Determine the combined weight of lug-
gage and cargo being loaded on the ve-
hicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in step 4.Step 6 (if applicable)
\1If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this reduces
the available cargo and luggage load
capacity of your vehicle.
The following table shows examples on
how to calculate total load, cargo load and
towing capacities with varying seating con-
figurations and number and size of occu-
pants. The following examples use a load
limit of 1500 lbs. This is for illustrative
purposes only. Make sure you are using
the actual load limit for your vehicle stated
on the vehicle’s tire and loading informa-
tion placard (\2page 206).
The higher the weight of all occupants, the
less cargo and luggage load capacity is
available.

Certification label
Even after careful determination of the
combined weight of all occupants, cargo
and the trailer tongue load (if applicable)
as to not exceed the permissible load limit,
you must make sure that your vehicle nev-
er exceeds the Gross Vehicle Weight Rat-
ing (GVWR) and the Gross Axle Weight
Rating (GAWR) for either the front or rear
axle and the Gross Combination Weights
Rating (GCWR) (if applicable).
Under a maximum loaded vehicle condi-
tion, gross axle weight ratings (GAWR’s) for
the front and rear axles must not be ex-
ceeded. USA only - for vehicles with a gross weight
capacity less than 10,000 lbs (4500 kg)
only:
To determine the maximum loading condi-
tions of your vehicle, locate the statement
"The combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs." on the tire and loading informa-
tion placard. The combined weight of occu-
pants, cargo/luggage and trailer tongue
weight (if applicable) should never exceed
the weight referenced here.
You can obtain the GVWR, the front/rear-
GAWR and the GCWR from the certification
label. The certification label can be found
below the driver’s seat on an outward fac-
ing position of the mounting pillar
(\2page 373).For more information on the trailer tongue
load, refer to "Trailer tongue load".
Gross Vehicle Weight Rating (GVWR):
The total weight of the vehicle, all occu-
pants, all cargo, and the trailer tongue load
must never exceed the GVWR.
Gross Axle Weight Rating (GAWR):
The total allowable weight that can be car-
ried by a single axle (front (FA) or rear (RA)).
Gross Combination Weight Rating (GCWR):
The total allowable weight of vehicle and
trailer when weighed in cominbation in-
cluding a 150 lbs (68 kg) allowance for the
presence of a driver.

To assure that your vehicle does not ex-
ceed the maximum permissible weight lim-
its (GVWR and GAWR for front and rear
axle), have the loaded vehicle (including
driver, passengers and all cargo and, if ap-
plicable, trailer fully loaded) weighed on a
suitable commercial scale.
Trailer tongue load
The tongue load (tongue weight at the
hitch ball) of any trailer is an important
weight to measure because it affects the
load you can carry in your vehicle. If a trail-
er is towed, the tongue load must be added
to the weight of all occupants riding and
any cargo you are carrying in the vehicle to
prevent exceeding your Sprinter tow vehi-
cle’s rear GAWR. The tongue load typically
is between 10% and 15% of the trailer
weight and everything loaded in it.
For example, if the trailer tongue load
equals 1 40 lbs and the determined avail-
able cargo/luggage and trailer tongue
weight equals 750 lbs, the amount of avail-
able cargo and luggage load capacity is
610 lbs. (750 – 140 = 610 lbs.)For further information on vehicle and trail-
er weights and ratings, loading a trailer and
trailer towing, see “Trailer towing”
(\2page 175).Your vehicle is equipped with either the
tire and loading information placard
1 or
with the tire inflation pressure placard lo-
cated on the driver’s door B-pillar.
The tire inflation pressure (including the
spare wheel) should be checked regularly
and adjusted as well as inspected for signs
of tire wear or visible damage. Use a good
quality pocket-type gauge to check tire in-
flation pressure.
Recommended tire inflation pres-
sureWarning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly 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 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.
