2020 MAZDA MODEL 3 HATCHBACK tire size

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 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.
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 conditi ons on specified
government test 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 a s the other tires on
your vehicle.
SAFETY WARNING
The following safety warning appears on
the tire's sidewall.

T115/70D16 90M 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 rating. Note
that the tire size and load index rating may
be different from the example.
T
Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).
11 5
“115” is the nominal w idth of the tire in
millimeters. This three-digit number gives
the width in millimet ers of the tire from
sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire.
70
“70” is the aspect ratio. This two-digit
number indicates the tire's ratio of height
to width.
D
“D” is the tire construction symbol. D
indicates “diagonal ply construction”.
16
“16” is the wheel rim diameter in inches.
90
“90” is the Load Index. This two-or
three-digit number indicates how much
weight each tire can support.
M
“M” is the speed rating. The speed rating
denotes the maximum speed for which the
use of the tire is rated.
Letter Rating Speed Rating M8 1 m ph

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 info rmation 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 the tires installed as
original equipment on
the vehicle. It is
very important that the 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 tire 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.

Vehicle Loading
▼Vehicle Loading
WA R N I N G
Do not tow a trailer with this vehicle:
Towing a trailer wi
th this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so will
affect the drive system which could result in
vehicle damage.
This section will guide you in the proper
loading of your vehicle, to keep your
loaded vehicle weight within its design
rating capability. Properly loading your
vehicle will provide maximum return of
vehicle design performance. Before
loading your vehicle, familiarize yourself
with the following terms for determining
your vehicle's weight ratings, from the
vehicle's Safety Certification Label and
Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is dangerous. The
results of overloading can have serious
consequences in terms of passenger safety.
Too much weight on a vehicle's suspension
system can cause spring or shock absorber
failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or
other damage.
Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases of
serious overloading, brakes can fail
completely, particularly on steep grades.
The load a tire will carry safely is a
combination of the size of the tire, its load
range, and corresponding inflation
pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings from
the vehicle's Safety Certification and Tire
and Load Information labels.
Base Curb Weight is the weight of the
vehicle including a f ull tank of fuel and
all standard equip ment. It does not
include passengers, cargo, or optional
equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it up
from your dealer plus any aftermarket
equipment.
