Recommended Tire Pressures
and Inflating Your Tires
Safe operation of your vehicle
requires that your tires are
properly inflated. Remember that
a tire can lose up to half of its air
pressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to
check the pressure of all tires and
adjust if required.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge (including spare, if
equipped). Inflate all tires to the
inflation pressure recommended
by Ford Motor Company. 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
255
Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 201902, Second-Printing Wheels and TiresA
BCDE

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!
You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
could be inaccurate. Ford
recommends 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
could cause uneven treadwear
patterns.
Always inflate your tires to the
Ford recommended inflation
pressure even if it is less than the
maximum inflation pressure
information found on the tire. You
will find a Tire Label containing
the Ford recommended tire
inflation pressure by the tire size
and other important information
located on the B-Pillar or the edge
of the driver ’s door. The Ford recommended tire
inflation pressure is also 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 on the
B-pillar, or on the edge of the
driver
’s door.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles.
Inspecting Your Tires and
Wheel Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects such as stones,
nails or glass that could be
wedged in the tread grooves.
Check the tire and valve stems for
holes, cracks, or cuts that could
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 demounted 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.

U.S. DOT Tire Identification
Number
Both United States 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 U.S. 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.
Tire Replacement
Requirements
Your vehicle is equipped with tires
designed to provide a safe ride
and handling capability.
WARNING: Only use
replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as 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 edge that meets the
door-latch post, next to the
driver's seating position), or the
Tire Label which is located on
the B-Pillar or edge of the
driver's door. If this information
is not found on these labels, then
you should contact your
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.

Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 201902, Second-Printing Wheels and Tires

WARNING: To reduce the
risk of serious injury, 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. WARNING: For a mounting
pressure more than
20 psi
(1.38 bar) greater than the
maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting. WARNING:
Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly. WARNING: When inflating
the tire for mounting pressures
up to
20 psi (1.38 bar) greater
than the maximum pressure on
the tire sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
• Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again. •
Stand at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair, if
the worn tires still have usable
tread depth. To avoid potential All
Wheel Drive (AWD) malfunction
or All Wheel Drive (AWD) system
damage, it is recommended to
replace all four tires rather than
mixing significantly worn tires with
new tires.
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor
Company could affect the
operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, your
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
could be damaged.

Tire Rotation
Note:
If your 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 could be
equipped with 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.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.
Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance information) will
help your tires wear more evenly,
providing better tire performance
and longer tire life. Sometimes
irregular tire wear can be
corrected by rotating the tires. Police Wheels and Tires
Wheel rims
To withstand the demands placed
on vehicles driven under heavy
duty service conditions, Ford
Motor Company installs heavy
duty wheels.
Tires
Tires (including the spare) are
speed-rated radials for police use.
Use only the recommended tire
size and speed ratings.
In regions with snow and ice
during the winter months,
installation of snow tires could be
desirable. Snow tires will usually
exhibit a drop in dry pavement
handling, but could show an
increase in snow and ice traction.
When snow tires are used, they
should be installed on all four
wheels, never on the drive wheels
only.

Tire storage
Most high performance tires are
made with a nylon overlay. As
such, the following steps should
be taken to avoid flatspotting
when the vehicles are not used for
a period of time.
•
Fleets should store the vehicles
with 44 psi (303 kPa) in the
tires.
• If the vehicle is stored for
periods longer than 30 days,
you should move it several feet
at least once during each
30-day period, so that a
different portion of the tread
contacts the ground.
• Tire pressure should be
reduced to the recommended
pressure shown on the vehicle
certification label before the
vehicle is placed back into
service.
USING SNOW CHAINS WARNING: Do not exceed 30 mph
(50 km/h)
. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use snow
chains on snow-free roads. WARNING:
Only fit snow chains
to specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING:
Snow tires must be
the same size, load index and speed
rating as those originally provided by
Ford. 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 control, vehicle rollover, personal
injury and death. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label 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.
Only use snow chains on rear wheels.
Install snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire sizes:
• 255/60R18
•Only install chains that are 10 mm
or less.
• 255/65R18
•Only install chains that are 10 mm
or less.
262
Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 201902, Second-Printing Wheels and Tires

•
265/60R18
•Only install chains that are 10 mm
or less.
• 255/55R20
•Only install chains that are 10 mm
or less.
We recommend you use steel wheels of
the same size and specification if snow
chains are required because chains may
chip aluminum wheels.
Follow these guidelines when using snow
tires and traction devices:
• If possible, avoid fully loading your
vehicle.
• Purchase snow chains from a
manufacturer that clearly labels body
to tire dimension restrictions. •
When driving with snow chains do not
exceed 30 mph (50 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Drive cautiously. If you hear the snow
chains rub or bang against the vehicle,
stop and tighten them. If this does not
work, remove the snow chains to
prevent vehicle damage.
• Remove the snow chains when they
are no longer needed. Do not use snow
chains on dry roads.
• If a temporary spare wheel is mounted
on your vehicle, do not use snow chains
on the axle with the temporary spare
wheel.
• Use snow chains that fit against the
sidewall of the tire to prevent the
chains from touching the wheel rims
or suspension, see following
illustration. If you have any questions regarding snow
chains, please contact your authorized
dealer.

TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.
Note: You should only use tire sealants in
roadside emergencies as they could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function. 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 could 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.
When the malfunction indicator is
illuminated, the system will not be able to
detect or signal low tire pressure as
intended. TPMS malfunctions could occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
This device complies with Part 15 of the
FCC Rules and with License exempt RSS
Standards of Industry Canada. Operation
is subject to the following two conditions:
1. This device will not cause harmful interference, and
