tion on uniform tire quality grad-
ing.
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
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 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative 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 one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative perfo rmance 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 high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement as measured under controlled
conditions on specified govern-
ment 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 corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory 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 Fed-
eral 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.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
