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 info rmation on uniform ti re 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 conform to Federal Safety Requ ire-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder an d
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 s peci-
fied government t est course.
For example, a tire graded 150 would wear one and a half (1 - 1 /2)
times as well on the governmen t course as a tire graded 100.
The relative performance of tires depends upon the actual condi -
tions of their use. Performance ma y differ significantly from the norm
due to variations in driving habits, service practices and diff erences
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 a s
measured under controlled conditions on specified government te st
surfaces of asphalt and concrete.
A tire marked C may have p oor traction performance.
Warning: The traction grade assigned to this tire is based on b raking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
Uniform Tire Quality Grading

Vehicle specifications
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the ge neration of heat and its ability to dissi-
pate heat when tested under contr olled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can c ause 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 passeng er
car tires must meet under the Fe deral Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is pro perly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can c ause heat buildup and possible t ire
failure.
