Overview ofTire Quality GradingStand -
ard s Uniform
TireQuality Grading Standards areU.S.
governmen tspecifications. Theirpurpose isto
provide driverswithuniform reliableinformation
on tire performance data.Tiremanufacturers
have tograde tiresusing threeperformance fac-
tors: 0043tread weargrade, 0044tract iongrade and
0087 temperature grade.Theseregulations donot
apply toCanada. Nevertheless, alltires soldin
North America areprovided withthecorre-
sponding qualitygrading markings onthe side-
wall ofthe tire.
Quality gradescanbefound, whereapplicab le,
on the tire sidewal lbetween treadshoulder and
maximum sectionwidth. Example:
R Tread weargrade: 200
R Tra ction grade: AA
R Temper aturegrade: A
All passenger cartires must confor mto the stat-
utory safety requirements inaddition tothese
grades.
i The
actual values fortires arevehicle-spe-
cific andmay deviate fromthevalues inthe
illustration.
Tread wear The
treadwear gradeisacomparative rating
based onthe wear rateofthe tire when tested
under controlled condition son aspecified U.S.
governmen tcourse. Forexample, atire graded
150 would wearoneandone-half timesaswell
on the governmen tcourse asatire graded 100.
The relative performance oftires depends upon
the actual condition sof their use,however, and
may depart significantly fromthenorm dueto
variations indriving habits, service practices
and differences inroad characterist icsand cli-
mate.
Tra ction G
WARNING
The tract iongrade assigned tothis tireis
based onstraight- aheadbraking traction
tests, anddoes notinclude acceleration, cor-
nering, hydropla ning,orpeak tractionchar-
acteristic s.
! Avoid
wheelspin. Thiscanlead todamage to
the drive train.
The tract iongrades –from highest tolowest –
are AA, A,Band C.Those grades represent the
tire's abilityto stop onwet pavement asmeas-
ured under controlled condition son specified
governmen ttest surfaces ofasphalt andcon-
crete. Atire marked Cmay have poortraction
performance.
The safe speed onawet, snow covered oricy
road isalwa yslower thanondry road surfaces.
You should payspecial attentiontoroad condi-
tions when temperatures arearound freezing

the sidewa llof each tireproduced. The
TINisaunique identification number.The
TIN enables thetire manufacturers orretreaders
to inform purchasers ofrecalls andother safety-
relevant matters. Itmakes itpossible forthe
purchaser toeasily identify theaffected tires.
The TINismade upofmanufacturer identifica-
tion code 0044,tire size 0087,tire type code 0085and
manufacturing date0083.
DOT (Departm entofTra nsporta tion):tire

Manufact ureridentification code:manufac-
turer identification code0044provides detailson
