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.

If the tire pressure m onitoring system has a malfunction, the t ire pressure warning light
flashes for about 1 minute when the ignition is switched ON and then continues illuminat-
ing. Have your vehicle checked by an Authorized Mazda Dealer as soon as possible.
WARNING
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, it is dangerous to drive the vehicle at high speeds, or
perform sudden maneuvering or braking. Vehicl e drivability could worsen and result in an
accident.
To determine if you have a slow leak or a flat, pull over to a safe position where you can
check the visual condition of the tire and determine if you have enough air to proceed to a
place where air may be added and the system monitored again by an Authorized Mazda
Dealer or a tire repair station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated. Have
the problem taken care of as soon as possible before it develops into a more serious situa‐
tion that could lead to tire failure and a dangerous accident.

If the tire pressure monitoring system warning
light illuminates or flashes, or the tire pressure
warning beep sound is heard, decrease vehicle
speed immediately and avoid sudden maneuver‐
ing and braking:
If the tire pressure monitoring system warning
light illuminates or
flashes, or the tire pressure
warning beep sound is heard, it is dangerous to
drive the vehicle at high speeds, or perform sud‐
den maneuvering or braking. Vehicle drivability
could worsen and result in an accident.
To determine if you have a slow leak or a flat, pull
over to a safe position where you can check the
visual condition of the tire and determine if you
have enough air to proceed to a place where air
may be added and the sy stem monitored again
by an Authorized Mazda Dealer or a tire repair
station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warn ing light is dangerous,
even if you know why it is illuminated. Have the
problem taken care of as soon as possible before
it develops into a more serious situation that
could lead to tire failure and a dangerous acci‐
dent. Inspect the tires and adjust to the specified in-
flation pressure (page 6-38).
NOTE
Perform tire pressure adjustment when the
tires are cold. Tire pressure will vary accord-
ing to the tire temperature, therefore let the ve-
hicle stand for 1 hour or only drive it 1.6 km (1
mile) or less before ad
justing the tire pres-
sures. When pressure is adjusted on hot tires to
the cold inflation pressure, the TPMS warning
light/beep may turn on af ter the tires cool and
pressure drops below specification.
Also, an illuminated TPMS warning light, re-
sulting from the tire air pressure dropping due
to cold ambient temper ature will remain illu-
minated even if the ambient temperature rises.
In this case, it will also be necessary to adjust
the tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air pres-
sure, make sure to check and adjust the tire air
pressures.
Tires lose air naturally over time and the
TPMS cannot tell if the tires are getting too
soft over time or yo u have a flat. However,
when you find one low tir e in a set of four-that
is an indication of trouble; you should have
someone drive the vehicle slowly forward so
you can inspect any low tire for cuts and any
metal objects sticking through tread or side-
wall. Put a few drops of water in the valve
stem to see if it bubble s indicating a bad valve.
Leaks need to be addressed by more than sim-
ply reinflating the tire as leaks are dangerous
― take it to an Authorized Mazda Dealer.

WA R N I N G
Keep your vehicle's tires properly inflated and not overloaded:
Driving with improperly inflated or overload ed 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 vehicl e 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.
▼ UNIFORM TIRE QUALITY GRADING
Quality grades can be found where applicable on the tire sidewa
ll between tread shoulder
and maximum section width.

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

MS or M/S: Mud and Snow
AT: All Terrain.
AS: All Season. The “M
S” or “M/S” indicates that the tire has some functional use in mud
and snow.
U.S. DOT Tire Identifi cation Number (TIN)
This begins with the letters “DOT” which indicates the tire mee ts all federal standards. The
next two numbers or letters are the plant code where it was man ufactured, and the last four
numbers represent the week and year the tire was manufactured. For example, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to f our digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-co ated fabric in the tire. In
general, the greater the number of plies, the more weight a tir e can support. Tire
manufacturers also must indicate the tire materials, which incl ude steel, nylon, polyester,
and other.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the
tire.
Maximum Permissible Inflation Pressure
This number is the greatest amoun t of air pressure that should ever be put in the tire under
normal driving conditions.
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 con ditions 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.

Mazda3_8GE4-EA-17F_Edition1 2017-4-7 11:59:21
Traction: The traction grades, from highe st to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measure d 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, represent ing the tire's
resistance to the generation of heat and its ability to dissipa te heat when tested under
controlled conditions on a spec ified indoor laboratory test whe el.
Snow Tires
In some heavy snow areas, local governments may require true sn ow tires, those with very
deeply cut tread. These tires should only be used in pairs or p laced 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 a ppears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
