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.
▼ Trea d Wea r
The tread wear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled
conditions on a speci
fied 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
signi ficantly from the norm because of
variations in driving habits, service
practices and di fferences 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
speci
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
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
laboratory test wheel than the
minimum required by law.

WARNING
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
in flated 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.

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

P215/65R15 95H 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 di fferent from
the example.
P
Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).
NOTE
If your tire size does not begin with a
letter this may mean it is designated by
either ETRTO (European Tire and Rim
Technical Organization) or JATMA
(Japan Tire Manufacturing
Association).
215
“215” is the nominal width of the tire
in millimeters. This three-digit number
gives the width in millimeters of the
tire from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire.
65
“65” is the aspect ratio. This two-digit
number indicates the tire's ratio of
height to width.
R
“R” is the tire construction symbol. R
indicates “Radial ply construction”.
15
“15” is the wheel rim diameter in
inches.

Tread Wear, Traction and Temperature
Grades
Tr ea d w ea r : The tread wear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a speci fied
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
speci fied 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 speci fied
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 as
the other tires on your vehicle.
SAFETY WARNING
The following safety warning appears
on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM :
EXPLOSION OF TIRE/RIM ASSEMBLY

Location of the Tire Label(Placard)
▼Location of the Tire Label (Placard)
Yo u w i l l 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 In
flation
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 in flation pressure is maintained.
Refer to Tires on page 9-10.
NOTE
Tire pressures listed on the vehicle
placard or tire information label
indicate the recommended cold tire
in flation 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.
WARNING
Always check the tire in flation
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-in flated tires is dangerous.
Under-in flation 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
fl at!
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 over fill 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.
