Treadwear
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 significantly from the norm due
to variations in driving habits, service practices and differences
in road characteristics and climate.
Traction A B C
The traction grades, from highest to lowest, are A, B, and C,
and they 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 traction grade assigned to this tire is based on
braking (straightahead) traction tests and does not
include cornering (turning) traction.
