6. Maximum load rating

This number indicates the maximum load
in kilograms and pounds that can be
carried by the tyre. When replacing the
tyres on the vehicle, always use a tyre
that has the same load rating as the
factory installed tyre.

7. Uniform tyre quality grading

Quality grades can be found where
applicable on the tyre sidewall between
tread shoulder and maximum section
width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
9 36

Tread wear

The tread wear grade is a comparative
rating based on the wear rate of the tyre
when tested under controlled conditions
on a specified government test course.
For example, a tyre graded 150 would
wear one-and-a-half times (1½) as well
on the government course as a tyre
graded 100.
The relative performance of tyres
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 side-
walls of passenger vehicle tyres. The
tyres available as standard or optional
equipment on your vehicle may vary with
respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tyre's ability to stop
on wet pavement as measured under
controlled conditions on
government test surfaces of asphalt and
concrete. A tyre marked C may have
poor traction performance.
WARNING
The traction grade assigned to this
tyre is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
