Uniform Tyre Quality Grading
WARNING
Qualitygrades can be found, where applicable,
on the sidewallof the tyre between the tread
shoulder and maximum section width.
The traction grade assigned to this tyre is
based on straight-ahead braking tests, and
does not include acceleration, cornering,
hydroplaning, or peak traction
For example:
Treadwear 200, Traction AA, Temperature A.
characteristics.
Tyres that are deep tread, winter-type snow
tyres are exempt from these grading
requirements and, consequently, the tyres
fitted to your vehicle may not carrythese
markings.
Temperature:
The temperature grades A(the highest), Band
C, and represent the tyre’s resistance to the
generation of heat and its abilityto dissipate
heat when tested under controlled conditions
on a specified indoor laboratorytest wheel.
Sustained high temperature can cause the
materialof the tyre to degenerate and reduce
tyre life, and excessive temperature can lead
to sudden tyre failure.
All passenger car tyres must conform to
federalsafetyrequirements in addition to
these grades.
Treadwear:
The treadwear 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
The grade ’C’corresponds to a levelof
performance which all passenger car tyres
must meet under the FederalMotor Safety
Standard No 109.
graded 150 would wear 1 /2 times as well on

the government course as a tyre graded 100.
The relative performance of tyres depends
upon the actualconditions of use, and may
depart significantlyfrom the norm due to
variations in driving habits, service practices
and differences in road characteristics and
climate.
Grades ’B’and ’A’represent higher levels of
performance on the laboratorytest wheel than
the minimum required by law.
WARNING
Temperature grades are established using
tyres that are properly inflated and not
overloaded. Excessive speed,
under-inflation or excessive loading, either
separately or in combination, can cause
heat build-up and possible tyre failure.
Traction:
The traction grades, from highest to lowest
are AA, A, Band C. These grades represent a
tyre’s abilityto stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. Atyre marked ’C’may have
poor traction performance.
