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.

Changing a wheel
Notes on selecting, installing andreplacingtires
Mercedes-AMGvehicles:observethe notes inthe Supplement. Otherwise,you may notrecog‐nize dangers.
You can askfor informationregarding permittedwheel/tire combinations at an authorizedMercedes-Benz Center.
\nWARNINGRisk of accident duetoincor‐rect dimensions of wheels and tires
If wheels and tires ofthe wrong size areinstalled,the wheel brakes or wheel suspen‐sion components may be damaged.
Alwaysreplace wheels and tires withthosethat fulfillthe specifications ofthe original part.
Whenreplacing wheels, make suretofitthecorrect:
RDesignation
RModel
Whenreplacing tires, make suretoinstallthecorrect:

RModel
\nWARNINGRisk of injurythroughexceed‐ingthe specified tire loadrating orthepermissible speedrating
Exceedingthe specified tire loadrating orthe permissible speedrating may leadtotiredamageandtothe tires bursting.
Therefore, only use tire types and sizesapprovedforyourvehicle model.
Observethe tire loadrating and speedratingrequiredforyourvehicle.
NOTEVehicle and tire damagethroughtire types and sizesthat havenot beenapproved
For safetyreasons, onlyuse tires, wheelsand accessories which havebeen speciallyapprovedbyMercedes-Benzforyourvehicle.
These tires are specially adaptedtothe con‐
trol systems, such as ABS, ESP®and4MATIC, and marked asfollows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended(run-flat tire onlyfor certain wheels)
RMO1 = Mercedes-Benz Original (only cer‐tain AMG tires)
Certaincharacteristics, such as handling,vehicle noise emissions, fuel consumption,etc. mayotherwise be adversely affected.Furthermore,other tire sizes couldresult inthe tiresrubbing againstthe body and axlecomponents when loaded. This couldresultin damagetothe tire orthevehicle.
Wheels and tires405

Observethefollowing when selecting, installingandreplacing tires:
ROnly use tires and wheels ofthe same type(summer tires, winter tires, MOExtendedtires) andthe same make.
ROnly install wheels ofthe same size on oneaxle (left andright).
It is only permissibletoinstall a differentwheel size intheevent of aflat tire in ordertodrivetothe specialistworkshop.
ROnly install tires ofthe correct size ontothewheels.
RVehicles with a tire pressure monitoringsystem:All installed wheels must be equip‐ped with functioning sensorsforthe tirepressure monitoring system.
RAttemperatures below 45 °F (7 °C), use win‐ter tires or all-season tires marked M+Sforall wheels.
Winter tires bearingtheMsnowflake sym‐bol in additiontothe M+S marking providethe best possible grip in wintryroad condi‐tions.
RFor M+S tires, only use tires withthe sametread.
RObservethe maximum permissible speedforthe M+S tires installed.
Ifthis is belowthevehicle's maximum speed,this must be indicatedbyan appropriatelabel inthe driver'sfield of vision.
RBreak in new tires at moderate speedsforthefirst 60 miles (100 km).
RReplacethe tires after sixyears atthe latest,regardless ofwear.
RWhenreplacing with tires that do notfea‐turerun-flatcharacteristics:vehicles withMOExtended tires are not equipped with aTIREFIT kit atthefactory.Equipthevehiclewith a TIREFIT kit afterreplacing with tiresthat do notfeaturerun-flatcharacteristics,e.g. winter tires.

Notes onrotating wheels
\nWARNINGRisk of injurythrough differ‐ent wheel sizes
Interchangingthe front andrear wheels ifthewheels or tires havedifferent dimensionsmay severelyimpairthe drivingcharacteris‐tics.
The wheel brakes or wheel suspension com‐ponents may also be damaged.
Rotatefront andrear wheels onlyifthewheels and tires are ofthe same dimen‐sions.
Wheels and tires407

Thewear patterns onthe front andrear wheelsdiffer:
RFront wheelswear more onthe shoulder ofthe tire
RRear wheelswear more inthe center ofthetire
Onvehiclesthat havethe same size front andrear wheels,rotatethe wheels accordingtotheintervals inthe tire manufacturer'swarrantybook inyourvehicle documents. Ifthis is notavailable,rotatethe tiresevery3,000to6,000 miles (5,000to10,000 km),depending onthewear. Ensurethatthe directionofrotation is maintained.
It is imperativetoobservethe instructions andsafety notes on "Changing a wheel" when doingso Preparingthevehiclefor a wheelchange(→page 409).
Notes onstoring wheels
Whenstoring wheels, observethefollowingnotes:
RAfterremoving wheels,storethem in a cool,dry and preferably dark place.
RProtectthe tires from contact withoil, greaseor fuel.
