tires MAZDA MODEL 3 HATCHBACK 2020 (in English) Owner's Guide

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 periodically or sooner if
irregular wear develops.
Please refer to Scheduled maintenance for
your tire rotation interval.
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.

▼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 tire 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.
1. New tread
2. Worn tread
3. Tread wear indicator

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 8-23.
▼Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make su
re 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 9-9.

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).

▼ 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.

Water Marks
Occurrence
Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these minerals
settles on the vehicle and evaporates, the
minerals will concentrate and harden to
form white rings. The rings can damage
your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve it s finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
The paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust forming
on your Mazda. Before this happens,
repair the damage by using Mazda
touch-up paint according to the
instructions in this section. Failure to
repair the affected area could lead to
serious rusting and expensive repairs.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish

adequately lubricated.
▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be
affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not
fit properly.
 Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.

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.

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.
Refer to Tire Inflation Pressure on page
6-31.
CAUTION
 Adjust the tire pressures while the tires
are cool. Because the air pressure in the
tires
fluctuates depending on the
temperature, before adjusting the tire
pressures, let the vehicle sit for an hour or
drive it only within a 1.6 km (1 mile)
distance. If the tire pressures are adjusted
while the tires are warm, the tire
pressures may decrease below the specified air pressure after cooling down
which could turn on the warning light. In
addition, because the air pressure in the
tires decreases when the ambient
temperature is low, if the ambient
temperature increases, an illuminated
TPMS warning light may turn off. Under
any circumstances, always adjust the tire
pressures while the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns off. If the TPMS
warning light does not turn off, drive the
vehicle at a speed of about 25 km (16
mph) or faster for 3 minutes or longer
and make sure the warning light turns
off.
If the TPMS warning light remains on
even after adjusting th e tire pressures, one
of the tires may have a puncture.

Uniform Tire Quality
Grading System (UTQGS)
▼ Uniform Tire Quality Grading
System (UTQGS)
This information relates to the tire grading
system developed by the U.S. National
Highway Traffic Safety
Administration for
grading tires by tread wear, traction, and
temperature performance.
▼ Tr e a d We a r
The tread wear grade is a comparative
rating based on the we
ar 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-a-half times as well on the
government course as a tire graded 100.

The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm because of variations in
driving habits, service practices and
differences in road characteristics and
climate.
▼ Traction-AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B, and C. These 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.
WA R N I N G
The traction grade assigned to this tire is
based on braking (straight ahead) traction
tests and does not include acceleration
cornering (turning), hydroplaning, or peak
traction characteristics.
▼Temperature-A, B, C
The temperature grades A (the highest), B,
and C, represent 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.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive
temperatures can lead to sudden tire
failure.

Grade C corresponds to a level of
performance which all passenger vehicle
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of
performance on the la
boratory test wheel
than the minimum required by law.
