2019 MAZDA MODEL 3 HATCHBACK tires

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 the 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 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-a-half times as well on the
government course as a tire graded 100.

The relative performan
ce 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 an
d 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.
▼ Te m p e r a t u r e - 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 laboratory test wheel
than the minimum required by law.

WA R N I N G
Keep your vehicle's tires properly inflated
and not overloaded:
Driving with improperly inflated or
overloaded tires is dangerous. Excessive
speed, underinflation, or excessive loading,
either separately or in combination, can
cause heat buildup and possible tire failure.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.

These grades will be added to the
sidewalls of passenger vehicle tires over
the next several years according to a
schedule established by the NHTSA and
the tire manufacturers.

The grade of tires available as standard or
optional equipment on Mazda vehicles
may vary with respect to grade.

ALL PASSENGER VEHICLE TIRES
MUST CONFORM TO THESE GRADES
AND TO ALL OTHER FEDERAL
TIRE-SAFETY REQUIREMENTS.

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.

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.

7. Repeat with each tire, including thespare.
NOTE
Some spare tires require higher
inflation pressure.
8. Visually inspect the tires to make sure
there are no nails or other objects
embedded that could poke a hole in the
tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or
other irregularities.
