2021 FORD MUSTANG Owners Manual

•
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.
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 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
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
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. Sometimes
irregular tire wear can be
corrected by rotating the tires.

and rear axle
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 sidewall. 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.
Mach 1 Handling Package (If Equipped)
Wheels
Your vehicle has unique wheels matched
to the tires. These wheels are more
susceptible to damage due to their
diameter, width, and low profile tires.
To avoid damage to your wheels:
• Maintain proper tire pressure
• When installing wheels, always torque
lug nuts to specification with a torque
wrench.
• Inspect your wheels for damage on a
regular basis. If a wheel is damaged,
replace it immediately.
• In the event that you encounter a
abnormally harsh impact, inspect the
outer diameter of your wheels, both
inside and out, for damage.

Tires
Your vehicle has low profile, high
performance tires that are designed to
optimize the driving dynamics you expect
in a Ford vehicle. These tires are not
optimized for off-road or winter (snow or
cold weather) performance, and their ride,
noise and wear characteristics are different
than non-performance tires. Also, because
of their lower profile, the tires are more
susceptible to damage due to potholes
and rough roads. Wheels (inches)

To make sure that your tires perform as
intended, it is important that you properly
maintain your tires:
• Your original equipment tires are
optimized for performance in both wet
and dry conditions. We do not
recommend using the original
equipment 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.
• The tires were designed for track use
and may exhibit significantly reduced
tread life and increased tire noise
compared to the standard equipment
tires under normal driving conditions.
Increasing the front camber settings
beyond the factory settings may further
accelerate tread wear and induce tire
noise.
• For tire pressures, see the placard
located on the B-pillar inside the driver
door.
• Always maintain your tire pressures
according to the tire information
placard on the driver door jamb, using
an accurate gauge.
• Tire pressures are specified cold and
should be checked after the vehicle has
been parked for at least three hours.
Do not reduce the pressure of warm
tires. •
Check your tire pressure often to
maintain it properly. Tire pressure can
diminish over time and fluctuate with
temperature.
• Do not overload your vehicle.
Maximum vehicle and axle weights are
listed on the tire information placard.
• Extra caution should be taken when
operating the vehicle near its maximum
load, including assuring proper tire
pressure and reducing speeds.
• Extra caution should be taken when
operating on rough roads to avoid
impacts that could cause tire damage.
• In the event that you encounter an
abnormally harsh impact, inspect your
tires for damage.
• Inspect your tires for damage on a
regular basis. If a tire is damaged,
immediately replace it.
• Proper suspension alignment is critical
for maximum performance and
optimal tire wear. If you notice uneven
tire wear, have your alignment checked.
• Rotate tires as recommended in the
tire rotation information. See Tire Care,
in the Wheels and Tires Chapter of the
Owner's Manual.
• Follow the rotation pattern for
"Vehicles equipped with different size
tires on the front and rear axle".
• When replacing tires, the only way to
maintain original performance is to use
the original equipment tire. If a different
tire is used, it should be the same size,
speed rating and load rating and be
replaced as a set of four. Never mix tire
brands.

USING WINTER TIRES
Inflate the winter tires to the same tire
pressures as those listed in the tire
pressures table.
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. USING SNOW CHAINS WARNING:
Aggressive driving in
any road conditions can cause you to
lose control of your vehicle increasing
the risk of severe personal injury or
property damage. The traction control
activating is an indication that at least
some of the tires have exceeded their
ability to grip the road; this may lead to
an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. If you experience a severe
road event, slow down
.
The tires on your vehicle could have
all-weather treads to provide traction in
rain and snow. In some climates you will
need to use snow tires and chains on your
vehicle in emergency situations or if
required by law.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• When possible, avoid fully loading your
vehicle.
• Chains could damage aluminum
wheels.
• Use ultra low profile cables, 10 mm or
less in dimension as measured on the
sidewall of your tire, with 235/55R 17,
235/50R18 and 255/40R19 on the rear
axle only.
• Do not use snow chains or cables with
265/40R19, 275/40R19, 305/30R19,
315/30R19, and 265/35R20
• Not all S-class snow chains or cables
meet these restrictions. Chains of this
size restriction will include a tensioning
device.
323
Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Wheels and TiresE278852

•
Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the front or the rear tires only.
• Do not exceed 30 mph (50 km/h) if
recommended by the chain
manufacturer while using snow chains.
• Install cables securely, verifying that
the cables do not touch any wiring,
brake lines or fuel lines.
• 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 tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
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 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.
324
Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Wheels and Tires

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.
