This information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answer any questions you may have as you
read this information.

DOT quality grades
All passenger vehicle tires must c onform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder and
maximum section width.

■Treadwear
The treadwear 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 (1 - 1/2) 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. Performance may differ significantly from the norm due to
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,
and they represent the tire’s ability to stop on wet pavement 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
(straight ahead) traction tests and does not include cornering (turning)
traction.
■
Temperature A, B, C
The temperature grades are A (the hi ghest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under cont rolled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degen-
erate and reduce tire life, and excessive temperature can lead to sud-
den tire failure.
Grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No.
109.
Grades B and A represent higher levels of performance on the labora-
tory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately
or in combination, can cause heat buildup and possible tire failure.
