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.
&WARNINGRisk 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:

RModel
Whenreplacing tires, make suretoinstallthecorrect:

RManufacturer
RModel
&WARNINGRisk 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.
454Wheels and tires

Only use tires, wheels and accessoriesthathavebeenchecked andrecommendedbyMercedes-Benz.
*NOTERisktodriving safety fromretrea‐ded tires
Retreaded tires are neithertested norrecom‐mendedbyMercedes-Benz, since previousdamage cannot always be detected onretreaded tires.
Forthisreason driving safety cannot be guar‐anteed.
#Do not use used tires ifyou havenoinformation abouttheir previous usage.
*NOTEPossible damagetowheels or tireswhen drivingover obstacles
Large wheels havea lower tire section width.The lowerthe tire section width,the greateristherisk of damagetowheels or tires whendrivingover obstacles.
#Avoid obstacles or drive particularlycarefully.
*NOTEDamagetoelectronic componentparts fromthe use of tire-mountingtools
Vehicles with a tire pressure monitoringsystem:Electronic component parts arelocated inthe wheel.Tire-mountingtoolsshould not be used inthe area ofthevalve.
This couldotherwise damagethe electroniccomponent parts.
#Havethe tireschanged at aqualifiedspecialistworkshop only.
*NOTEDamagetosummer tires at lowambienttemperatures
Atlow ambienttemperatures,tears couldformwhen driving with summer tires, caus‐ing permanent damagetothe tires.
#Attemperatures below 45 °F (7 °C),use M+S tires .
Accessory partsthat are not approvedforyourvehiclebyMercedes-Benz or are not being usedcorrectly can impairthe operating safety.
Before purchasing and using non-approvedaccessories, visit aqualified specialistworkshopand inquire about:
RSuitability
RLegalstipulations
RFactoryrecommendations
&WARNINGRisk of accident withhighperformance tires
The special tire tread in combination withtheoptimized tire compound meansthattheriskof skidding orhydroplaning onwetroads isincreased.
In addition,the tire grip is greatlyreduced ata low outsidetemperature and tirerunningtemperature.
#Switch onthe ESP®and adaptyourdrivingstyle accordingly.
#Use M+S tire at outsidetemperaturesof lessthan10°C (50 °F).
Wheels and tires455

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.

Notes onrotating wheels
&WARNINGRisk of injurythrough differ‐ent wheel sizes
Interchangingthe front andrear wheels ifthewheels or tires havedifferent dimensionsmay severely impairthe 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.

Observethe notes on operatingfluids(→page 468).
&WARNINGRisk of an accident duetovapor pocketsforming inthe brake sys‐tem
The brakefluid constantly absorbs moisturefromthe air. This lowersthe boiling point ofthe brakefluid. Ifthe boiling point istoo low,vapor pockets mayforminthe brake systemwhenthe brakes are applied hard.
This causesthe braking effecttobeimpaired.
