Unifor m Tire Quality Grading System
(UTQGS)
This information relates to the tire grading system developed b y the
U.S. National Highway Traffic Saf ety Administration for grading tires
by tread wear, traction, and temperature performance.
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under con trolled conditions on a specified gov-
ernment 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 condi tions
of their use, however, and may depart significantly from the no rm
because of variations in driving habits, service practices and differ-
ences in road characteristics and climate.
The traction grades, from highest to lowest, are AA, A, B, and C.
These grades represent the tire’s ability to stop on wet paveme nt as
measured under controlled conditio ns on specified 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 (s traight
ahead) traction tests and does not include acceleration corneri ng (turn-
ing), hydroplaning, or peak traction characteristics.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to w ear
abnormally. Here are some important maintenance points:
Inspect all tire pressure monthly (including the spare) when th e tires
are cold. Maintain recommended pressures for the best ride, top han-
dling, and minimum tire wear. Use the pressures specified on th e
vehicle tire information placard or tire label for optimum service.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Inspect the tires for uneven w ear and damage. Abnormal wear is usu-
ally 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 specification ( P. 582) and
inspect the lug nu ts for tightness.

NOTICE
Rotate unidirectional tires and radial tires that have an asymm etrical
tread pattern or studs only from front to rear, not from side t o side. Tire
performance will be weak ened if rotated from side to side.
