2019 MAZDA MODEL 3 HATCHBACK inflation pressure

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.
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 recom mended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification 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.
▼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 16,000 km (10,000
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 (U.S.A.
and Puerto Rico) on page 6-4.
Refer to Scheduled Maintenance (Canada)
on page 6-6.
Refer to Scheduled Maintenance (Mexico)
on page 6-8.

During rotation, inspect them for correct
balance.

1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

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 9-9) 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.

The light turns on if
any door/trunk lid/
liftgate is not closed securely.
Action to be taken
Close the door/trunk lid/liftgate securely.
▼ Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Turns on)
If a tire pressure d
ecreases below the
specified air pressure, the TPMS warning
light turns on.
At the same time, a message and the tire
pressure of each tire are displayed on the
multi-information disp lay alternately. In
addition, the tire (s) with low air pressure
is displayed in yellow.
WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the
TPMS warning light is turned on or flashing
is dangerous because the brake
performance and the steering wheel
operability will be reduced. If the vehicle is
driven at high speeds or the brakes are
suddenly applied, it could lead to an
accident. Gradually apply the brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of the
TPMS warning light is dangerous because a
tire may burst which could lead to an
accident. Take appropriate measures as
soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a tire
position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for the
tire positions may be different from the
actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressu res to the appropriate
pressures.

Tire Labeling
▼Tire Labeling
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires.
This information
identifies and describes the fundamental
characteristics of the tire and also provides
a tire identification number for safety
standard certification and in case of a
recall.

Tread Wear, Traction and Temperature
Grades
Tr e a d w e a r : The tread wear grade is a
comparative rating based on the wear rate
of the tire when test ed 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.
Traction: 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 test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
Te m p e r a t u r e : 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 us ed 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.

Location of the Tire Label(Placard)
▼Location of the Tire Label (Placard)
You will find the tire label containing tire
inflation pressure by tire size and other
important information on the driver's side
B-pillar or on the edge of the driver's door
frame.

SAMPLE
▼Recommended Tire Inflation
Pressure
On the tire label you will find the
recommended tire inflation pressure in
both kPa and psi for th
e tires installed as
original equipment o n the vehicle. It is
very important that th e inflation pressure
of the tires on your vehicle is maintained
at the recommended pressure. You should
check the tire pressure regularly to insure
that the proper inflation pressure is
maintained.
Refer to Tires on page 9-9.
NOTE
Tire pressures listed on the vehicle placard
or tire information label indicate the
recommended cold tire inflation pressure,
measured when the tires are cold, after the
vehicle has been parked for at least 3
hours. As you drive, the temperature in the
tire warms up, increasing the tire pressure.
WA R N I N G
Always check the tire inflation pressures on
a regular basis according to the
recommended tire inflation pressure on the
tire label and in conjunction with the
information in this owner's manual:
Driving your vehicle with under-inflated
tires is dangerous.
Under-inflation is the most common cause
of failures in any kind of tire and may result
in severe cracking, tread separation or
“blowout”, with unexpected loss of vehicle
control and increased risk of injury.
Under-inflation increases sidewall
flexing
and rolling resistance, resulting in heat
buildup and internal damage to the tire. It
results in unnecessary tire stress, irregular
wear, loss of control and accidents. A tire
can lose up to half of its air pressure and
not appear to be flat!
It is impossible to determine whether or not
tires are properly inflated just by looking at
them.
▼ Checking Tire Pressure
1. When you check the air pressure, make
sure the tires are cold ―meaning they
are not hot from driving even a mile.
2. Remove the cap from the valve on one
tire.
3. Firmly press a t ire gauge onto the
valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by
pushing on the metal stem in the center
of the valve. Then recheck the pressure
with your tire gauge.
6. Replace the valve cap.
