manufacturers also must
indicate the ply materials
in the tire and the
sidewall, which include
steel, nylon, polyester,
and others.
Maximum Load:
Indicates the maximum
load in kilograms and
pounds that can be
carried by the tire. Refer to
the Safety Compliance
K
Certification Label
(affixed to either the door
hinge pillar, door-latch
post, or the door edge
that meets the door-latch
post, next to the driver

Treadwear, Traction
and Temperature
Grades:Treadwear The
treadwear grade is a
comparative rating based
on the wear rate of the tire
L
when tested under
controlled conditions on
a specified government
test course. For example,
a tire graded 150 would
wear one and one-half
times as well on the
government course as a
tire graded 100. Traction:
The traction grades, from
highest to lowest are AA,
A, B, and C. The grades
represent the tire's ability
to stop on wet pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C
may have poor traction
performance.
Temperature:
The
temperature grades are A
(the highest), B and C,
representing the tire's
resistance to the
generation of heat and its
ability to dissipate heat
when tested under
controlled conditions on
a specified indoor
laboratory test wheel.
Maximum Inflation
Pressure:
Indicates the
tire manufacturer's
maximum permissible
pressure or the pressure
at which the maximum
M
load can be carried by the
tire. This pressure is
normally higher than the
manufacturer's
recommended cold
inflation pressure, which
can be found on the
Safety Compliance
Certification Label
(affixed to either the door
hinge pillar, door-latch
post, or the door edge
that meets the door-latch

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
You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. We
recommend the use of a digital or
dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Always inflate the tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. The
recommended tire inflation
pressure is found on the Safety
Compliance Certification Label
(affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch
post, next to the driver seating
position), or Tire Label which is
located on the B-Pillar or the edge
of the driver door. Failure to follow
the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles
Note:
Do not reduce tire pressure
to change the ride characteristics
of your vehicle. If you do not
maintain the tire pressures as
specified by Ford, your vehicle may
experience a condition known as
shimmy. This will cause severe
vibration and oscillations in the
steering wheel when your vehicle
travels over a bump or dip in the
road and is unable to dampen out
by itself. Significantly
under-inflated tires, incorrect tire
usage or any vehicle modifications
such as lift-kits can cause your
vehicle to shimmy. If your vehicle
begins to shimmy, slowly reduce
the speed of your vehicle by
pressing the brake pedal or
releasing the accelerator pedal. As
your vehicle speed reduces the
shimmy will cease.
The maximum inflation pressure
is the tire manufacturer's
maximum permissible pressure or
the pressure at which the
maximum load can be carried by
the tire. This pressure is normally
higher than the manufacturer ’s
recommended cold inflation
pressure, which can be found on
the Safety Compliance
Certification Label (affixed to
either the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver seating
position), or Tire Label which is
located on the B-Pillar or the edge
252
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.

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
Note:
The wheel valve stems must
also be replaced when the road
tires are replaced on your vehicle.
Fitting Replacement Tires WARNINGS
When mounting replacement
tires and wheels, you should
not exceed the maximum pressure
indicated on the sidewall of the
tire to set the beads without
additional precautions listed
below. If the beads do not seat at
the maximum pressure indicated,
re-lubricate and try again. For mounting pressures
above 20 psi (1.38 bar)
greater than the maximum
pressure on the tire sidewall, the
tire should be replaced by a tire
professional. For mounting pressures up to 1.38
bar greater than the maximum
pressure on the tire sidewall, the
following precautions must be
taken:
•
Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area.
• Stand at a minimum of
12.1 ft
(3.7 m) away from the wheel
and tire assembly.
• Use eye and ear protection. Tire Pressure Monitoring
System
(If Equipped)
The use of wheels or tires not
recommended by Ford Motor
Company may affect the
operation of the tire pressure
monitoring system. If the tire
pressure monitoring system
indicator is flashing, the tire
pressure monitoring system is
malfunctioning. The replacement
tire might be incompatible with
the tire pressure monitoring
system, or a component of the tire
pressure monitoring system may
be damaged. See
Tire Pressure
Monitoring System (page 260).
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
Tire Safety Practices WARNINGS
If your vehicle is stuck in
snow, mud, sand, etc., do not
rapidly spin the tires. Spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds.
