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
Traffi c Safety Administration for grading tires by tread wear, traction, and temperature
performance.
Tread Wear
The tread wear grade is a comparative rating based on the wear rate of t\
he tire when tested
under controlled conditions on a specifi ed government test course.
For example, a tire graded 150 would wear one-and-a-half times as well o\
n 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 signifi cantly 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 cond\
itions on specifi ed
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 c\
ontrolled conditions on
a specifi ed indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degener\
ate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger vehicl\
e 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 requ\
ired by law.

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 different 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 ei\
ther 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.
6 5
“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 co\
nstruction”.
1 5
“15” is the wheel rim diameter in inches.
9 5
“95” is the Load Index. This two-or three-digit number indicates how much weight each tire
can support.

Maximum Permissible Infl ation Pressure
This number is the greatest amount of air pressure that should ever be p\
ut in the tire under
normal driving conditions.
Tread Wear, Traction and Temperature Grades
Tread wear: The tread wear grade is a comparative rating based on the wear rate of t\
he tire
when tested under controlled conditions on a specifi ed 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 c\
ontrolled conditions
on specifi ed 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 specifi ed 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. M\
ake
sure you purchase snow tires that are the same size and construction typ\
e as the other tires
on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
 y  EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH
TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa) TO SEAT
BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
 y  TIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/DAMAGE-
FOLLOW OWNER'S MANUAL AND PLACARD IN VEHICLE-FREQUENTLY
CHECK INFLATION PRESSURE AND INSPECT FOR DAMAGE.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnor\
mally. Here are
some important maintenance points:
Tire Infl ation Pressure
Inspect all tire pressure monthly (including the spare) when the tires\
are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire \
wear. Use the
pressures specifi ed on the vehicle tire information placard or tire label for optimum ser\
vice.
Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or soon\
er
if irregular wear develops. Mazda recommends to rotate every 8,000 km (\
5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
 y
 Incorrect tire pressure y Improper wheel alignment y Out-of-balance wheel y Severe braking
After rotation, infl ate all tire pressures to specifi cation (page 9-10 ) 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 weakened if
rotated from side to side.
