inflation pressure FORD EXPLORER 2020 User Guide

If you feel a sudden vibration or
ride disturbance while driving, or
you suspect your tire or 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 your 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
your 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 your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension (if
equipped) 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 has a tire pressure
monitoring system, then you
need to update the settings for
the system sensors. Always
perform the system reset
procedure after tire rotation. If
you do not reset the system, it
may not provide a low tire
pressure warning when
necessary.
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 may 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.

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. •
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.

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 may cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it may 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 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.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may 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.

Changing Tires With a Tire
Pressure Monitoring System Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See
When Inflating Your Tires in
this chapter.

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure
to follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about
2 –4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure. Tire Pressure Monitoring System Reset
Procedure WARNING:
To determine the
required pressure(s) for your vehicle, see
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 the Tire Label on the
B-Pillar or the edge of the driver door.
Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation.
To provide the vehicle's load carrying
capability, some vehicles require different
recommended tire pressures in the front
tires as compared to the rear tires. The tire
pressure monitoring system equipped on
these vehicles is designed to illuminate the
low tire pressure warning light at two
different pressures; one for the front tires
and one for the rear tires.
Since tires need to be rotated to provide
consistent performance and maximum tire
life, the tire pressure monitoring system
needs to know when the tires are rotated
to determine which set of tires are on the
front and which are on the rear. With this
information, the system can detect and
properly warn of low tire pressures.
