2018 MAZDA MODEL CX-9 tire size

CAUTION
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 ha s 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 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-in flated 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 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 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 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 for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire
deflation or blow out.

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 9-9) 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 9-9.
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, handling, and minimum tire
wear.
Refer to the specificat ion charts (page 9-
9).
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.

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 8-26.
▼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.

Changing a Flat Tire
NOTE
If the following occurs while driving, it
could indicate a flat tire.
•Steering becomes difficult.
•The vehicle begins to vibrate
excessively.
•The vehicle pulls in one direction.
If you have a flat tire, drive slowly to a
level spot that is well off the road and out
of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a
busy road is dangerous.
WA R N I N G
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not done
properly. The vehicle can slip off the jack
and seriously injure someone.
No person should place any portion of their
body under a vehicle that is supported by a
jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a vehicle
supported by a jack is dangerous. The
occupant could cause the vehicle to fall
resulting in serious injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, level surface off the right-of-way and firml y set the parking
brake.
2. Shift into Park (P) and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle and away from the vehicle and traffic.
5. Remove the jack, tool, and spare tire
(page 7-3).
6. Block the wheel diagonally opposite
the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.

P215/65R15 95H is an example of a tire size and load index rating. Here is an explanation
of the various components of that tire size and load index rati ng. Note that the tire size and
load index rating may be different from the example.
P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
NOTE
If your tire size does not begin with a letter this may mean it is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing
Association).
215
“215” is the nominal w idth of the tire in millimeters. This thr ee-digit number gives the
width in millimeters o f the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
65
“65” is the aspect ratio. This t wo-digit number indicates the t ire's ratio of height to width.
R
“R” is the tire construction symbol. R indicates “Radial ply co nstruction”.
15
“15” is the wheel rim diameter in inches.
95
“95” is the Load Index. This two-or three-digit number indicate s how much weight each tire
can support.
