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 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
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.
Improper or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all your
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
one sixteenth of an inch (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 one
sixteenth of an inch (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.
Damage
Periodically inspect the tire treads
and sidewalls for damage (such
as bulges in the tread or sidewalls,
cracks in the tread groove and
separation in the tread or
sidewall). If damage is observed
230
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and TiresE142546

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.
Age
WARNING: Tires degrade
over time depending on many
factors such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives. WARNING:
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. WARNING:
You should
replace your spare tire when you
replace the road tires or after six
years due to aging even if it has
not been used. U.S. DOT Tire Identification
Number (TIN)
Both U.S. 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.
231
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and Tires

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. 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:
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:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and
wheel bead seat area again.
3. Stand at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
4. Use both eye and ear
protection.
232
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and Tires

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.
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.
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 may affect the
operation of your tire pressure
monitoring system.
If the TPMS indicator is flashing,
your TPMS is malfunctioning. Your
replacement tire might be
incompatible with your TPMS, or
some component of the TPMS
may be damaged.
Safety Practices WARNING:
If your vehicle is
stuck in snow, mud or sand, 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. WARNING:
Do not spin the
wheels at over 34 mph (55 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 ’s 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 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
233
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and Tires

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’re
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
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.
Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.
Front-wheel drive vehicles (front
tires on the left side of the
diagram) 234
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and TiresE142547

Sometimes irregular tire wear can
be corrected by rotating the tires.
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 about 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 WINTER TIRES WARNING:
When you use winter
tires on your vehicle, you must make sure
that you use the correct lug nuts.
If winter tires are used, you must make sure
that you use the correct tire pressures.
USING SNOW CHAINS WARNING:
Your vehicle is not
approved for use with snow chains.
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.
235
2018 Fiesta (CCT) Canada/United States of America, JE8J 19A321 AB enUSA, Edition date: 201706, First-Printing Wheels and Tires

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.
Installation of any tires that are not the
original equipment tire size can cause the
speedometer to display incorrect vehicle
speed.
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.
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 may not cause harmful
interference, and
2. This device must accept any interference received, including
interference that may cause undesired
operation.
Note: Changes or modifications not
expressively approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
The term "IC:" before the radio certification
number only signifies that Industry Canada
technical specifications were met.

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 Inflating Your Tires in this chapter. Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. The low tire pressure warning
light will turn on if the tire pressure is
significantly low. Once the light is
illuminated, your tires are under-inflated
and need to be inflated to the
manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

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
If you get a flat tire while driving, do not
apply the brake heavily. 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 235). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
an authorized dealer inspect the tire
pressure monitoring system sensor for
damage. Note:
The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full functionality
of the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
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:
1. T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded
in the sidewall.
2. Full-size dissimilar spare with label
on wheel:
This spare tire has a label
on the wheel that states: THIS WHEEL
AND TIRE ASSEMBLY FOR
TEMPORARY USE ONLY.
3. Full-size dissimilar spare without
label on wheel.
