Unifonn TireQuality Grading

Quality grades canbefound where applicable on
the tire sidewall between treadshoulder andmax-
imum section width.

142
PracticalTips,Emergency Service
Example

All passenger cartires must conform toFederal
Safety Requirements inaddition tothese grades.
Treadwear

The treadwear gradeisacomparative rating
based onthe wear rateofthe tire when tested un-
der controlled conditions onaspecific govern-
ment testcourse.
For example, atire graded 150would wearone
and ahalf (1-1/2) timesaswell onthe government
course asatire graded 100.
The relative performance oftires depends upon
the actual conditions oftheir use,however, and
may depart significantly fromthenorm duetovari-
ations indriving habits, service practices anddif-
ferences inroad characteristics andclimate.

Traction AA,A,B,C

The traction grades,fromhighest tolowest, are
AA, A,S,and Cand they represent thetire's ability
to stop onwet pavement asmeasured undercon-
trolled conditions onspecified government test
surfaces ofasphalt andconcrete.
A tire marked Cmay have poortraction perfor-
mance.

A
Warning!

The traction gradeassigned tothis isbased on
braking (straight-ahead) tractiontestsanddoes
not include cornering (turned)traction, accelera-
tion, hydroplaning orpeak traction characteris-
tics.

Temperature A,8,C

The temperature gradesareA(the highest), Band
C, representing thetire's resistance tothe gener-
ation ofheat anditsability todissipate heatwhen
tested undercontrolled conditions onaspecified
indoor laboratory testwheel.
Sustained hightemperatures cancause themate-
rial ofthe tire todegenerate andreduce tirelife,
and excessive temperature canlead tosudden
tire failure.
The grade Ccorresponds toalevel ofperfor-
mance whichallpassenger cartires must meet
under theFederal MotorVehicle SafetyStandard

No. 109.

Grades Band Arepresent higherlevelsofperfor-
mance onthe laboratory testwheel thanthemini-
mum required bylaw.

A
Warning!

The temperature gradeforthis tireisestablished
for atire that isproperly inflatedandnotoverload-

ed.

Excessive speed,underinflation, orexcessive
loading, eitherseparately orincombination, can
cause heatbuildup andpossible tirefailure.
Tire
pressures

A
Warning!
Incorrect tirepressure causesincreased tire
wear andadversely affectsroadhandling.

I>
Always useanaccurate tirepressure gauge
when checking inflationpressures.

I>
Donot exceed themaximum tirepressure list-
ed onthe tire sidewall.
Please observe thechapter "VEHICLE IDENTI-
FICATION, TECHNICAL DATA"onPage 179.

I>
Cold tireinflation pressure means:alltires
must becold, ambient temperature maximum
68°F (20°C), whenadjusting theinflation pres-
sure.
Avoid sunlight strikingthetires before measur-
ing cold pressures, sincethepressures would
rise from temperature influence.

I>
Valve capsprotect thevalve fromdustand
dirt, andthus from leakage.
Always screwcapstightly down.
Replace missingcapsimmediately.

I>
Donot use commercially availablesealantor
tire inflating bottles.
Tire
traction

A
Warning!
When driving onwet orslushy roads,a
wedge ofwater maybuild upbetween the
tires andtheroad. Thisphenomenon is
known as"hydroplane" andmay cause par-
tial orcomplete lossoftraction, vehicle
control orstopping ability.
I>
Reduce speedonwet surface toprevent this.

Tire life

Tire lifedepends onvarious factors, i.e., road
surfaces, trafficandweather conditions, driving
habits, typeoftires andtirecare.

I>
Inspect yourtires forwear anddamage before
driving off.Ifyou notice uneven orsubstantial
wear, wheels mightneedalignment ortires
should bebalanced orreplaced.
