tires MAZDA MODEL CX-9 2021 Owner's Guide

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e 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-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s 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 ti re 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 wi ll flash for approximately one minute and then
remain continuously illuminated. This sequen ce 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 th at 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.
 To avoid false readings, the system samples fo r a little while before indicating a problem. As
a result it will not instantaneously regi ster a rapid tire deflation or blow out.
▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire pressure sensor to
the receiver unit.
When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
When excess snow or ice adheres to the
vehicle, especially around the wheels.
When the tire pressure sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in
the sidewalls.
When using tire chains.

▼Tires and Wheels
CAUTION
When inspecting or adjusting the tire air
pressures, do not apply excessive force to
the stem part of the wheel unit. The stem
part could be damaged.
Changing tires and wheels
The following proced
ure allows the TPMS
to recognize a tire pressure sensor's unique
ID signal code whenever tires or wheels
are changed, such as changing to and from
winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to do it is to have
an Authorized Mazda Dealer, change your
tire and complete ID signal code
registration.
When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer,
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.

When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, switch the ignition ON, th en back to ACC or
OFF.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15
minutes of changing tires, the tire pressure
monitoring system warn ing light will flash
because the sensor ID signal code would
not have been registered. If this happens,
park the vehicle for about 15 minutes,
after which the sensor ID signal code will
register upon driving the vehicle for 10
minutes.
Replacing tires and wheels
CAUTION
 When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
 The wheels equipped on your Mazda are
specially designed for installation of the
tire pressure sensors. Do not use
non-genuine wheels, otherwise it may
not be possible to inst all the tire pressure
sensors.
Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are possible.
The tire pressure sensor is removed
from the old wheel an d installed to the
new one.

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-7) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-7.

CX-9_8JK1-EA-20G_Edition6_old
2021-12-8 9:30:44

Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handlin g, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
▼ Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance on page
6-4.

During rotation, inspect them for correct
balance.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel

Severe braking

After rotation, inflate all tire pressures to
specification (page 9-7) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial tires
that have an asymmetrical tread pattern or
studs only from front to rear, not from side
to side. Tire performance will be reduced if
rotated from side to side.
▼ Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and traction
could result in an accident.
Replace all four tires at the same time:
Replacing just one ti
re is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle control.
Mazda strongly recommends that you
replace all four tires at the same time.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.
NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-25.
▼Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is properly
inflated and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction which is
lighter and smaller than a conventional

tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

CAUTION
Do not use your temporary spare tire rim
with a snow tire or a conventional tire.
Neither will properly fit and could
damage both tire and rim.
 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 The temporary spare tire is for limited
use, however, if the tread wear
solid-band indicator appears, replace the
tire with the same type of temporary
spare (page 6-36).
NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The

Refer to Tire Labeling on page 8-25.
▼ Replacing a Wheel
WA R N I N G
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be
affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
*
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
