5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. DOT Tire Quality Grading (U.S.
Vehicles)
The tires on your vehicle meet all
U.S. Federal Safety Requirements.
All tires are also graded for
treadwear, traction, and
temperature performance
according to Department of
Transportation (DOT) standards.
Uniform tire quality grading
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
Tread wear
The tread wear 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-a-half times (1½) 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.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary depending on the grade.
Traction - AA, A, B & C
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.
WARNING
The traction grade assigned to this
tire is based on straight ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
