Glossary of Tire Terminology
Cold Tire Pressure –
The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating –
The maximum load that a tire is rated to carry for a given inflation
pressure.
Maximum Inflation Pressure –
The maximum tire air pressure that the tire can
hold.
Maximum Load Rating –
The load rating for a tire at the maximum permissible
inflation pressure for that tire.
Recommended Inflation Pressure –
The cold tire inflation pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) –
The projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.
DOT Tire Quality Grading
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.
n
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
All passenger car tires must conform to Federal Safety Requirements in addition to these
grades.
n
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.
