TireQuality Grading
In accordance withthe US Department ofTrans‐portation's "Uniform TireQuality GradingStand‐ards", tire manufacturers arerequiredtogradetheir tires onthe basis ofthefollowingthree per‐formancefactors:
1Treadweargrade
2Tractiongrade
3Temperature grade
%The data shown inthe image isexampledata.
%The classification is not legallystipulatedforCanada, but it isgenerallystated.
TreadweargradeThe treadwear grade is a comparativeratingbased onthewearrateofthe tire whentestedunder controlled conditions on a specifiedtesttrack ofthe US Department ofTransportation.Forexample, a tiregraded150wouldwear one
446Wheels and tires

and one-half times aswell onthe governmenttesttrack as a tire graded100.
Therelative performance of tires depends uponthe actual conditions oftheir use, however,andmay depart significantly fromthe norm duetovariations in driving habits, service practices anddifferences inroadcharacteristics and climateconditions.
Tractiongrade
&DANGERRisk of accident duetoinade‐quate traction
The tractiongrade assignedtothis tire isbased onstraight-ahead braking tractiontests, and does not include either accelera‐tion, cornering,hydroplaning or peak tractioncharacteristics.
#Always adaptyour drivingstyle anddrive at a speedtosuitthe prevailingtraffic andweather conditions.
*NOTEDamagetothe drivetrain fromwheelspin
#Avoid wheelspin.
The traction grades – from highesttolowest –are AA,A,B and C. Those gradesrepresentthetire's abilitytostop onwet pavement as meas‐ured under controlled conditions on specifiedgovernmenttestsurfaces made of asphalt andconcrete.
Temperaturegrade
&WARNINGRisk of accident from tireoverheating and tirefailure
Thetemperature gradeforthis tire is estab‐lishedfor a tirethat is properly inflated andnotoverloaded. Excessive speed, underinfla‐tion, orexcessive loading, either separatelyor in combination, can causeexcessive heatbuild-up and possible tirefailure.
#Observetherecommended tire pres‐sures andregularlycheckthe tire pres‐
sure of all tires includingthe sparewheel.
#Adjustthe tire pressure as necessary.
Thetemperature grades are A (the highest), Band C. Theyrepresentthe tire'sresistancetothegeneration of heat and its abilitytodissipateheat whentested under controlled conditions ona specified indoor laboratorytestwheel. Sus‐tained hightemperature can causethe materialofthe tiretodegenerate andreduce tire life, andexcessivetemperature can leadtosudden tirefailure. Grade C correspondstoa level of per‐formance which all passenger car tires mustmeet undertherequirements ofthe US Depart‐ment ofTransportation.

these are installed onthevehicle, but does notinclude passengers or luggage.
Maximum tire load:the maximum tire load isthe maximum permissibleweight in kilograms orlbsfor whicha tire is approved.
Maximum permissible tire pressure:maxi‐mum permissible tire pressurefor one tire.
Maximum load on one tire:maximum load onone tire. This is calculatedbydividingthe maxi‐mum axle load of one axlebytwo.
PSI (pounds per square inch):standard unit ofmeasurementfor tire pressure.
Aspectratio:ratio between tire height and tirewidth in percent.
Tirepressure:pressure insidethe tire applyingan outwardforcetoeverysquare inch ofthe tire.The tire pressure is specified in pounds persquare inch (psi), in kilopascals (kPa) or in bar.The tire pressure should only be corrected whenthe tires are cold.
Cold tire pressure:the tires are cold whenthevehicle has been parkedfor at least3 hours
without direct sunlight onthe tires orthevehiclehas been drivenfor lessthan 1 mile (1.6 km).
Tirecontact surface:the part ofthe tirethatcomes into contact with theroad.
Tirebead:the purpose ofthe tire bead istoensurethatthe tire sits securely onthe wheelrim. There are several wire cores inthe tire beadtopreventthe tire fromchanging length onthewheelrim.
Sidewall:the part ofthe tire betweenthe treadandthe tire bead.
Weight of optional equipment:the combinedweight ofthe optional equipmentweighing morethanthereplacedstandard parts and morethan5 lbs (2.3kg).This optional equipment, such ashigh-performance brakes, level control system, aroof luggagerackor high-performance batteries,is not included inthe curbweight andtheweightofthe accessories.
TIN (Tire IdentificationNumber):a uniqueidentification number which can be usedby atire manufacturertoidentify tires,forexample,in a productrecall, andthus identifythe pur‐chasers. The TIN is made up ofthe manufactur‐
er's identity code, tire size, tire type code andthe manufacturing date.
Load-bearing index:the load-bearing index is acodethat containsthe maximum load-bearingcapacity of a tire.
Traction:traction isthe gripresulting from fric‐tion betweenthe tires andtheroad surface.
Wear indicator:narrowbars (treadwear bars)that are distributedoverthe tire contact surface.Ifthe tire tread is level withthe bars,thewearlimit of 1/16in (1.6 mm) has beenreached.
Distribution ofvehicle occupants:distributionofvehicle occupantsover designated seat posi‐tions in avehicle.
Maximum permissible payloadweight:nomi‐nal load and luggage load plus150 lb (68kg)multipliedbythe number of seats inthevehicle.

&WARNINGRisk of an accident duetoinsufficient tire pressure
Tirepressuresthat aretoo low posethefollowing hazards:
RThe tires may burst, especially asthe load andvehicle speed increase.
RThe tires maywearexcessively and/or unevenly,which may greatly impair tire traction.
RThe drivingcharacteristics, aswell assteering and braking, may be greatly impaired.
You couldthen lose control ofthevehicle.
