7-20 Maintenance
United States Department of
Transportation/Uniform Tyre Quality
Grades
The following information relates to the
tyre grading system developed by the
National Highway Traffic Safety
Administration which will grade tyres by
tread wear, traction and temperature
performance.
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 (1.5) times 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. Traction – A, B, C
The traction grades, from the highest to
the lowest are ‘
A’, ‘ B’ and ‘ C’, and they
represent the tyre’s ability to stop on wet
pavements as measured under controlled
conditions on specified 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 braking (straight
ahead) traction tests and does not
include cornering (turning) traction. Temperature – A, B, C
The temperature grades ‘
A’ (the highest),
‘ B ’ and ‘C ’ representing the tyre’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tyre to degenerate and
reduce tyre life, and excessive
temperature can lead to sudden tyre
failure.
The grade ‘ C’ corresponds to a level of
performance which all passenger car
tyres must meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades ‘ B’ and ‘ A’ represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
!WARNING:
The temperature grade for this tyre is
established for a tyre that is properly
inflated and not over loaded.
Excessive speed, under-inflation or
excessive loading, either separately
or in combination, can cause heat
build-up and possible tyre failure.
