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 t ires 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 on e-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 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 meas
ured under controlled conditions on specified
government test surfaces of asphalt and conc rete. 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.
▼ 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 abili
ty 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.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
▼Tire Inflation 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 specified on the vehicle tire informat
ion placard or tire label for optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and di
stribute 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:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tire pressures to sp ecification (page 9-8) 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.
