Quality grades can be found, where
applicable, on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear
The treadwear grade is a comparative rat-
ing 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
Tire manufacturers are required to grade
tires based on three performance
factors: treadwear, traction and
temperature resistance.

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.
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
