This information is provided in compliance
with the requirements of the National High-
way Traffic Safety Administration, Depart-
ment of Transportation. It provides the
purchasers and/or prospective purchasers
with information on reporting safety defects.
DOT quality grades - All passenger vehicle
tires must conform to Federal Safety Require-
ments in addition to these grades. The spe-
cific grade rating in each grade category is
shown on the side wall of the tires on your
vehicle.
The treadwear grade is a comparative 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 one-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, however, and may depart signifi-
cantly from the norm due to 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. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.
The temperature grades are A (the highest), B
and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified 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. The grade C corre-
sponds 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 laboratory test wheel than
the minimum required by law.

If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform the
National Highway Traffic Safety
Administration (NHTSA) in addi-
tion to notifying Mitsubishi Motors
Corporation.

Uniform tire quality grading
Treadwear
Traction AA, A, B, C
WARNING
The traction grade assigned to the tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B, C
WARNING
The temperature grade for the tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.
