USING SUMMER TIRES
Summer tires provide superior
performance on wet and dry roads.
Summer tires do not have the Mud and
Snow (M+S or M/S) tire traction rating on
the tire side wall. Since summer tires do
not have the same traction performance
as All-season or Snow tires, we do not
recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear
and environmental conditions) or in snow
and ice conditions. Like any tire, summer
tire performance is affected by tire wear
and environmental conditions. If you must
drive in those conditions, we recommend
using Mud and Snow (M+S, M/S),
All-season or Snow tires.
Always store your summer tires indoors at
temperatures above
19°F (-7°C). The
rubber compounds used in these tires lose
flexibility and may develop surface cracks
in the tread area at temperatures below
19°F (-7°C)
. If the tires have been
subjected to 19°F (-7°C) or less, warm
them in a heated space to at least 41°F
(5°C) for at least 24 hours before installing
them on a vehicle, or moving the vehicle
with the tires installed, or checking tire
inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply
heat or blow heated air directly on the tires.
Always inspect the tires after storage
periods and before use. USING 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 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. It is also
strongly advised to follow the Ford
recommended tire inflation pressure 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 ’s 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.
The tires on your vehicle (excluding the
265/45ZR20 Sport Tire) may have
all-weather treads to provide traction in
rain and snow. However, in some climates
you may need to use snow chains.
Your vehicle may not be compatible with
snow chain or cable usage with the
factory-fitted wheels and tires. Only
certain chains or snow cables have been
approved by Ford as safe for use on your
vehicle with the following wheel and tire
combination(s): 18” x8”x44mm Wheel and
P245/60 R18 Tire. You should only install
chains or cables that have been rated as
10 mm or less in dimension as measured
on the sidewall of your tire. Not all S-class
snow chains meet these restrictions.
Chains of this size restriction will include a
332
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-Printing Wheels and Tires

tensioning device. The chains should be
mounted in pairs on the front tires only. If
you need to use chains, it is recommended
that steel wheels (of the same size and
specification) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow
tires and traction devices
•
If possible, avoid fully loading your
vehicle
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions.
• When driving with tire cables do not
exceed 30 mph (48 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Drive cautiously. If you hear the cables
rub or bang against the vehicle, stop
and retighten them. If this does not
work, remove the cables to prevent
vehicle damage.
• Remove the cables when they are no
longer needed. Do not use cables 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
tire.
If you have any questions regarding snow
chains or cables, 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

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.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it may
not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle. If you get a flat tire when driving, do not
heavily apply the brake. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 333). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.
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
and can be one of three types:

Tire Change Procedure WARNING:
When one of the front
wheels is off the ground, the transmission
alone will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to secure
the wheel diagonally opposite to the wheel
being changed. For example, when
changing the front left wheel, place an
appropriate block or wheel chock on the
right rear wheel.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that
attach the rotor to the hub so they do not interfere with the mounting surfaces of the
wheel. Installing wheels without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle
is in motion, resulting in loss of vehicle control, personal injury or death. Ib-ft (Nm)
