2018 FORD FIESTA tire size

T type tires have some additional
information beyond those of P
type tires; these differences are
described below:
A.
T: Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service on
cars, SUVs, minivans and light
trucks.
B. 145:
Indicates the nominal
width of the tire in millimeters
from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire. C.
80:
Indicates the aspect ratio
which gives the tire's ratio of
height to width. Numbers of 70 or
lower indicate a short sidewall.
D. D:
Indicates a diagonal type tire.
R:
Indicates a radial type tire.
E. 16:
Indicates the wheel or rim
diameter in inches. If you change
your wheel size, you will have to
purchase new tires to match the
new wheel diameter.
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 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 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.

When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of 1
psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your
tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note:
If you are checking tire
pressure when the tire is hot, (i.e.
driven more than 1 mile [1.6 km]),
never bleed or reduce air 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 your tire(s),
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 air pressure inside to go
up as you drive.
2. Remove the cap from the valve
on one tire, then firmly press the
tire gauge onto the valve and
measure the pressure. 3. Add enough air to reach the
recommended air pressure.
Note:
If you overfill the tire, release
air by pressing on the metal stem
in the center of the valve. Then
recheck the pressure with your tire
gauge.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
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.
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.

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.

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

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

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.

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:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough off
the road to avoid the danger of being hit
when operating the jack or changing the
wheel. 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. WARNING:
Do not get under a
vehicle that is only supported by a vehicle
jack.
