uuChecking and Maintaining TiresuDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
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. The following explains these gradings. Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maxi mum section width.
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.
