Uniform Tire Quality GradingThis information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S.A. 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 answ er any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires mu st conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A

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 (1.5) 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 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 cond itions 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 (turn-
ing) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing 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.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden 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 labo-
ratory test wheel than the minimum required by law.

cent plies
Pneumatic tire A mechanical device made of rubber, chemi-
cals, fabric and steel or
other materials, that,
when mounted on an automotive wheel, pro-
vides the traction and contains the gas or fluid
that sustains the load
Radial ply tire A pneumatic tire in which the ply cords that
extend to the beads are laid at substantially 90
degrees to the centerline of the tread
Reinforced tire A tire designed to operate at higher loads and
at higher inflation pressures than the corre-
sponding standard tire
Section width The linear distance between the exteriors of
the sidewalls of an inflated tire, excluding ele-
vations due to labeling, decoration, or protec-
tive bands
Sidewall That portion of a tire between the tread and
bead
Sidewall separation The parting of the rubber compound from the
cord material in the sidewall
Snow tire A tire that attains a traction index equal to or
greater than 110, compared to the ASTM-E
1136 Standard Reference Test Tire, when
using the snow traction test as described in
ASTM F-1805-00, Standard Test Method for
Signal Wheel Driving Traction in a Straight Line
on Snow-and Ice-Covered Surfaces, and which
is marked with an Alpine Symbol ( ) on at
least one sidewall
Te s t r i m The rim on which a tire is fitted for testing, and
may be any rim listed as appropriate for use
