2021 MAZDA MODEL CX-30 tire type

Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified
value, the system
notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures
can be checked using the center
display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
NOTE
When the ambient temperature is
low, the tire temperatures also
decrease. If the tire temperatures
decrease, the air pressure in the tires
will also decrease which could turn
on the TPMS warning light.
Before driving, visually inspect the
tires for abnormalities. Additionally,
inspect the tire pressures monthly. A
digital type air pressure gauge is
recommended for inspecting the tire
pressures.
The TPMS is not a substitute for your
own periodic inspection of the tires.
Always inspect the tires yourself
periodically.
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 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.

Tires
▼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.
WARNING
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 9-8)
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
WARNING
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 9-8.

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 6-33).
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 8-24.
▼ Replacing a Wheel
WARNING
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.

Tread Wear, Traction and Temperature
Grades
Trea d wea r : The tread wear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For example,
a tire graded 150 would wear one and
one-half (1 1/2) times as well on the
government course as a tire graded
100.
Tra c t i o n : The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on
specified government te
st surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
Temperature: The temperature grades
are A (the highest), B and C,
representing the tire's resistance to the
generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local
governments may require true snow
tires, those with very deeply cut tread.
These tires should only be used in pairs
or placed on all four wheels. Make
sure you purchase snow tires that are
the same size and construction type as
the other tires on your vehicle.
SAFETY WARNING
The following safety warning appears
on the tire's sidewall.
