\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 bearingthe Msnowflake 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.

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.
