WARNING

Risk of injury through exceeding the specified tyre load-bearing

capacity or the permissible speed rating

Exceeding the load-bearing capacity of the tyres can lead to tyre dam‐

age and could cause the tyres to explode.

Therefore, only use tyre types and sizes approved for your

vehicle model.

Observe the tyre load-bearing capacity rating and speed rating

required for your vehicle.

NOTE

Vehicle and tyre damage caused by non-approved tyre types and

sizes

For safety reasons, only use tyres, wheels and accessories which have

been specially approved by Mercedes-Benz for your vehicle.

THESE TYRES ARE SPECIFICALLY CONFIGURED FOR ACTIVE

SAFETY SYSTEMS SUCH AS ABS, ESP

AND 4MATIC, AND ARE

MARKED AS FOLLOWS:

MO = Mercedes-Benz Original

MOE = Mercedes-Benz Original Extended (tyres with run-flat char‐

acteristics, only for certain wheels)

MO1/MO1A = Mercedes-Benz Original (only certain AMG tyres)

Otherwise certain properties such as driving characteristics, noise emis‐

sions, consumption, etc. could be adversely affected. Furthermore,

other tyre sizes could result in the tyres rubbing against the body and

axle components when loaded. This could result in damage to the tyre

or the vehicle.

Only use tyres, wheels and accessories that have been checked and

recommended by Mercedes-Benz.

NOTE

Risk to driving safety from retreaded tyres

Retreaded tyres are neither tested nor recommended by Mercedes-

Benz, since previous damage cannot always be detected on retreaded

tyres.

For this reason driving safety cannot be guaranteed.

Do not use used tyres if you have no information about their

previous usage.

NOTE

Possible wheel and tyre damage when driving over obstacles

Large wheels have a smaller section width. As the section width decrea‐

ses, the risk of wheels and tyres being damaged when driving over

obstacles increases.

Avoid obstacles or drive especially carefully.

Reduce your speed when driving over kerbs, speed bumps,

manhole covers and potholes.

Avoid particularly high kerbs.

NOTE

Possible wheel and tyre damage when parking on kerbs or in

potholes

Parking on kerbs or in potholes can damage the wheels and tyres.

Only park on level surfaces if possible.

Avoid kerbs and potholes when parking.

NOTE

Damage to electronic component parts due to the use of tyre-fit‐

ting tools

Vehicles with tyre pressure monitoring system: there are electronic

components in the wheel.

Positioning tyre-fitting tools in the area of the valve may damage the

electronic components.

Tyre-fitting tools should not be applied in the area of the

valve.

Always have tyres changed at a qualified specialist workshop.

NOTE

Damage to summer tyres at low ambient temperatures

At low ambient temperatures, tears could form when driving with sum‐

mer tyres, causing permanent damage to the tyre.

At temperatures below 7 °C use i M+S tyres.

Accessory parts which are not approved for your vehicle by Mercedes-Benz, or

which are not used correctly, can impair driving safety.

BEFORE PURCHASING AND USING NON-APPROVED ACCESSORIES, VISIT

A QUALIFIED SPECIALIST WORKSHOP AND INQUIRE ABOUT THE FOL‐

LOWING POINTS:

Suitability

Legal provisions

Factory recommendations

WARNING

Risk of accident with sport tyres

The special tyre tread in combination with the optimised tyre com‐

pound means that the risk of skidding or aquaplaning on wet roads is

increased.

In addition, the tyre grip is greatly reduced at a low outside temperature

and tyre running temperature.

Switch on the ESP

and adapt your driving style accordingly.

Use i M+S tyres at outside temperatures of less than 7 °C.

Only use tyres suitable for the intended use.

OBSERVE THE FOLLOWING WHEN SELECTING, ASSEMBLING AND REPLAC‐

ING TYRES:

Country-specific requirements for tyre approval that define a specific

tyre type for your vehicle.

G-Class - Owner's Manual

Wheels and tyres Wheel change

F465 0034 02

622

Furthermore, the use of certain tyre types in certain regions and areas of

operation can be highly beneficial.

Only use tyres and wheels of the same type (summer tyres, winter tyres)

and the same manufacture.

Only fit wheels of the same size on one axle (left and right).

It is only permissible to fit a different wheel size in the event of a flat

tyre in order to drive to the specialist workshop.

Only fit tyres of the correct size onto the wheels.

Do not make any modifications to the brake system, the wheels or the

tyres.

The use of shims or brake dust shields is not permitted and may invalid‐

ate the vehicle's general operating permit.

Vehicles with a tyre pressure monitoring system: All fitted wheels

must be equipped with functioning sensors for the tyre pressure moni‐

toring system.

At temperatures below 7 °C, use winter tyres or all-season tyres marked

M+S on all wheels.

Winter tyres bearing the i snowflake symbol in addition to the M+S

marking provide the best possible grip in wintry road conditions.

For M+S tyres, only use tyres with the same tread.

Observe the maximum permissible speed for the M+S tyres fitted.

If this is below the vehicle's maximum speed, this must be indicated in

an appropriate label in the driver's field of vision.

Drive the vehicle with new tyres at moderate speeds for the first 100 km.

Replace the tyres after six years at the latest, regardless of wear.

For more information on wheels and tyres, contact a qualified specialist work‐

shop.

Notes on changing wheels

WARNING

Risk of injury through different wheel sizes

Interchanging the front and rear wheels can severely impair the driving

characteristics.

The disk brakes or wheel suspension components may also be dam‐

aged.

Only interchange the front and rear wheels if the wheels and

tyres have the same dimensions.

Interchanging the front and rear wheels if the wheels or tyres have different

dimensions can render the general operating permit invalid.

Observe the instructions and safety notes on "Changing a wheel"

(/page619).

THE WEAR PATTERNS ON THE FRONT AND REAR WHEELS DIFFER:

front wheels wear more on the tyre shoulder

rear wheels wear more in the centre of the tyre

Do not drive with tyres that have too little tread depth. This significantly

reduces traction on wet roads (aquaplaning).

G-Class - Owner's Manual

On vehicles with the same front and rear wheel size, you can interchange the

wheels every 5000 to 10,000 km, depending on the wear. Ensure the direction

of rotation is maintained for the wheels.

Notes on storing wheels

WHEN STORING WHEELS, OBSERVE THE FOLLOWING NOTES:

After removing wheels, store them in a cool, dry and preferably dark

place.

Protect the tyres from contact with oil, grease or fuel.
