2021 MAZDA MODEL CX-9 tire pressure

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
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.
▼ 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.

Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key
and apply pressure. Turn the wrench
counterclockwise.
To install the antitheft lug nut

CAUTION
Tuck a cloth between the flat tire and
the vehicle trim. If the flat tire directly
contacts the vehicle trim, the trim may
be damaged.
9. Slowly close the liftgate while making sure that the liftgate trim does not
contact the flat tire.
NOTE
If the liftgate trim contacts the flat tire,
adjust the position of the flat tire.
10. Make sure that the liftgate closes
securely.
11. Check the tire inflation pressure. Refer to the spec ification charts on
page 9-7.
12. Have the flat tire repaired or replaced
as soon as possible.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.

Warning Light If the tire pressure monitoring system has
a malfunction, the tire pressure warning light
flashes. Have your vehicle checked by an Au thorized Mazda Dealer as soon as possible.
WA R N I N G
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pres‐
sure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, it is dangerous to drive the vehicle at high speeds, or
perform sudden maneuvering or braking. Vehicle drivability could worsen and result in an
accident.
To determine if you have a slow leak or a flat, pull over to a safe position where you can
check the visual condition of the tire and determine if you have enough air to proceed to a
place where air may be added and the system monitored again by an Authorized Mazda
Dealer or a tire repair station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated. Have
the problem taken care of as soon as possible before it develops into a more serious situa‐
tion that could lead to tire failure and a dangerous accident.

Action to be taken
Inspect the tires and adjust to the sp ecified inflation pressure (page 6-34).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sens ors may be damaged.
NOTE
Perform tire pressure adjustment when the tires are cold . Tire pressure will vary according to the tire temper‐
ature, therefore let the vehicle stand for 1 hour or only drive it 1.6 km (1 mile) or less before adjusting the
tire pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/
beep may turn on after the tires cool and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from the tire air pressure dropping due to cold ambient
temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TPMS warnin g light illuminates due to a drop in tire air pressure, make sure to check
and adjust the tire air pressures.
After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the
TPMS warning light remains illuminate d, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you
have a flat. However, when you find one low tire in a set of four-that is an indication of trouble; you should
have someone drive the vehicle slowly forward so you can inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Put a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addr essed by more than simply refilling the trouble tire as leaks are dangerous
― take it to an Authorized Mazda Dealer which has all the equipment to fix tires, TPMS systems and order
the best replacement tire for your vehicle.
If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.
