•
Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up
or damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up
or damaging underbody components.
All other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use. As a result of the above dimensional
differences, sport-utility vehicles, vans and
trucks often will have a higher center of
gravity and a greater difference in center
of gravity between the loaded and
unloaded condition.
These differences that make your vehicle
so versatile also make it handle differently
than an ordinary passenger car. TIRE CARE
Information About Uniform
Tire Quality Grades
Tire Quality Grades apply to new
pneumatic passenger car tires.
The tire Quality Grades can be
found where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example: Treadwear 200
Traction AA Temperature A.
They do not apply to deep tread,
winter-type snow tires,
space-saver or temporary use
spare tires, light truck or LT type
tires, tires with nominal rim
diameters of 10 to 12 inches or
limited production tires as defined
in Title 49 Code of Federal
Regulations Part 575.104 (C)(2).
Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set.

United States of America DOT
Tire Identification Number
(TIN)
United States of America, and
Canada Federal regulations
require tire manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a United States of
America DOT Tire Identification
Number for safety standard
certification and in case of a recall.
This begins with the letters DOT
and indicates that the tire meets
all federal standards. The next
two numbers or letters are the
plant code designating where it
was manufactured, the next two
are the tire size code and the last
four numbers represent the week
and year the tire was built. For
example, the numbers 317 mean
the 31st week of 1997. After 2000
the numbers go to four digits. For
example, 2501 means the 25th
week of 2001. The numbers in
between are identification codes
used for traceability. This
information is used to contact
customers if a tire defect requires
a recall.
Location of the Tire Label
You will find a Tire Label
containing tire inflation pressure
by tire size and other important
information located on the B-Pillar
or the edge of the driver's door.
Inflating the Tires WARNING
Under-inflation is the most
common cause of tire failures
and may result in severe tire
cracking, tread separation or
blowout, with unexpected loss of
vehicle control and increased risk
of injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat! Safe operation of your vehicle
requires that the tires are correctly
inflated.
Every day before you drive, check
the tires. If one looks lower than
the others, use a tire gauge to
check pressure of all tires and
adjust if required.
At least once a month and before
long trips inspect each tire
including the spare tire. Check the
tire pressure with a tire pressure
gauge. Inflate all tires to the
correct inflation pressure.
251
Transit (TTH) Canada/United States of America, enUSA, First Printing Wheels and Tires
of the driver door. The cold
inflation pressure should never be
set lower than the recommended
pressure on the Safety
Compliance Certification Label or
Tire Label.
When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of
10 psi (0.7 bar) in inflation
pressure. Check the tire pressures
frequently and adjust them to the
correct pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the tire pressures:
1. Make sure the tires are cool, meaning they are not hot from
driving even a mile.
2. Remove the cap from the valve
on one tire, then firmly press
the tire gauge onto the valve
and measure the tire pressure.
3. Add enough air to reach the
recommended tire pressure.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.
7. Check the sidewalls to make sure there are no gouges, cuts
or bulges. Note:
If you are checking tire
pressure when the tire is hot, for
example you have driven more than
1.0 mi (1.6 km)
, never bleed or
reduce tire pressure. The tires are
hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.
Note: If you have to drive a
distance to get air for the tires,
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the tire pressure to increase
as you drive.
Note: If you over inflate the tire,
release air by pressing on the metal
stem in the center of the valve.
Then recheck the pressure with
your tire gauge.
Note: Some spare tires operate at
a higher inflation pressure than the
other tires. For T-type mini-spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at
60 psi (4.15 bar).
For full-size and dissimilar spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label.

Inspecting the Tires and Wheel
Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects, for example
stones, nails or glass that may be
wedged in the tread grooves.
Check the tire and valve stems for
holes, cracks, or cuts that may
permit air leakage and repair or
replace the tire and replace the
valve stem. Inspect the tire
sidewalls for cracking, cuts,
bruises and other signs of damage
or excessive wear. If internal
damage to the tire is suspected,
have the tire removed and
inspected in case it needs to be
repaired or replaced. For your
safety, tires that are damaged or
show signs of excessive wear
should not be used because they
are more likely to blow out or fail.
Incorrect or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all the
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:
Tire Wear When the tread is worn down to
0.08 in (2 mm), tires must be
replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which
look like narrow strips of smooth
rubber across the tread will
appear on the tire when the tread
is worn down to
0.08 in (2 mm).
When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.
Tire Damage
Periodically inspect the tire treads
and sidewalls for damage, for
example bulges in the tread or
sidewalls, cracks in the tread
groove or separation in the tread
or sidewall. If damage is observed
or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.

Tire Age
WARNING
Tires degrade over time
depending on many factors,
for example weather, storage
conditions, and conditions of use,
for example load, speed and
inflation pressures the tires
experience throughout their lives.
In general, tires should be
replaced after six years regardless
of tread wear. However, heat
caused by hot climates or
frequent high loading conditions
can accelerate the aging process
and may require tires to be
replaced more frequently.
You should replace the spare tire
when you replace the road tires or
after six years due to aging even if
it has not been used. Tire Replacement
Requirements
WARNINGS
Only use replacement tires
and wheels that are the same
size, load index, speed rating and
type, (for example P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel size
may be found on either the Safety
Compliance Certification Label
(affixed to either the door hinge
pillar, door-latch post, or the door WARNINGS
edge that meets the door-latch
post, next to the driver seating
position), or the Tire Label which
is located on the B-Pillar or edge
of the driver door. If this
information is not found on these
labels, then you should contact an
authorized dealer as soon as
possible. Use of any tire or wheel
not recommended by Ford can
affect the safety and performance
of your vehicle, which could result
in an increased risk of loss of
vehicle control, vehicle rollover,
personal injury and death.
Additionally the use of
non-recommended tires and
wheels could cause steering,
suspension, axle, transfer case or
power transfer unit failure. If you
have questions regarding tire
replacement, contact an
authorized dealer as soon as
possible. Always inflate steel carcass
tires with a remote air fill with
the person inflating standing at a
minimum of 12.1 ft (3.7 m) away
from the wheel and tire assembly. Your vehicle is fitted with tires
designed to provide a safe ride
and handling capability.
We recommend that the two front
tires or two rear tires generally be
replaced as a pair.
255
Transit (TTH) Canada/United States of America, enUSA, First Printing Wheels and Tires
WARNINGS
Do not spin the wheels at
over 35 mph (56 km/h). The
tires may fail and injure a
passenger or bystander. Driving habits have a great deal to
do with your tire mileage and
safety:
•
Observe posted speed limits.
• Avoid fast starts, stops and
turns.
• Avoid potholes and objects on
the road.
• Do not run over curbs or hit the
tire against a curb when
parking.
Highway Hazards
No matter how carefully you drive
there is always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect a tire or your vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and replace it with the spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
the tires. If your vehicle seems to
pull to one side when you are
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of the tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.

Tire Rotation
WARNING
If the tire label shows
different tire pressures for the
front and rear tires and the vehicle
is fitted with a tire pressure
monitoring system, the settings
for the system sensors need to be
reset. Always carry out the system
reset procedure after tire rotation.
If the system is not reset, it may
not provide a low tire pressure
warning when necessary. See Tire
Pressure Monitoring System
(page 260). Rotating the tires at the
recommended interval detailed in
the Scheduled Maintenance
chapter will help the tires wear
more evenly, providing better tire
performance and longer tire life.
Sometimes irregular tire wear can
be corrected by rotating the tires.
Note:
After rotating the tires the
inflation pressure must be checked
and adjusted to the vehicle
requirements.
Note: If the tires show uneven
wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation. Note:
Your vehicle may have a
dissimilar spare wheel and tire
assembly. A dissimilar spare wheel
and tire assembly is defined as a
spare wheel and tire assembly that
is different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly it is
intended for temporary use only
and should not be used in a tire
rotation.

TIRE PRESSURE MONITORING
SYSTEM (If Equipped) WARNING
The tire pressure monitoring system
is not a substitute for manually
checking tire pressure. The tire
pressure should be checked periodically
(at least monthly) using a tire gauge, see
Inflating your tires in this chapter. Failure
to properly maintain your tire pressure
could increase the risk of tire failure, loss
of control, vehicle rollover and personal
injury. Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated
to the inflation pressure recommended by
the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If
your vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle ’s handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
