Notes on regularly inspecting wheels and tyres

WARNING

Risk of injury due to damaged tyres

Damaged tyres can cause tyre pressure loss.

Check the tyres regularly for signs of damage and replace any

damaged tyres immediately.

WARNING

Risk of aquaplaning due to insufficient tyre tread

Insufficient tyre tread will result in reduced tyre grip. There is a risk of

an accident.

On a wet road surface the risk of aquaplaning is increased, in particular

where speed is not adapted to suit the conditions.

Check the tread depth and the condition of the tyre contact

surface across the entire width of all tyres on a regular basis.

MINIMUM TREAD DEPTH FOR

Summer tyres: 3 mm

M+S tyres: 4 mm

For safety reasons, replace the tyres before the legally-prescri‐

bed limit for the minimum tread depth is reached.

Replace the tyres immediately if the legally-prescribed limit for

the minimum tread depth is reached.

CARRY OUT THE FOLLOWING CHECKS ON ALL WHEELS REGULARLY, AT

LEAST ONCE A MONTH OR AS REQUIRED, FOR EXAMPLE, PRIOR TO A

LONG JOURNEY OR DRIVING OFF-ROAD:

Check the tyre pressure (/page615).

Notes on snow chains

OBSERVE THE FOLLOWING NOTES WHEN USING SNOW CHAINS:

Snow chains are only permissible for certain wheel/tyre combinations.

You can obtain information about this from a Mercedes-Benz Service

Centre.

For safety reasons, only use snow chains that have been specifically

approved for your vehicle by Mercedes-Benz, or snow chains of the same

quality standard.

If snow chains are fitted, the maximum permissible speed is 50 km/h.

Vehicles with Active Parking Assist: do not use Active Parking Assist

when snow chains are fitted.

Do not switch off ESP

if snow chains are fitted.

Tyre pressure

Notes on tyre pressure

WARNING

Risk of an accident due to tyre pressure that is insufficient or too

high

TYRES WITH A PRESSURE THAT IS INSUFFICIENT OR TOO HIGH

POSE THE FOLLOWING DANGERS IN PARTICULAR:

The tyres can burst.

The tyres can wear excessively and/or unevenly.

The driving characteristics as well as the steering‑ and braking

may be greatly impaired.

Observe the recommended tyre pressures and check the tyre

pressure of all tyres including the spare wheel:

monthly

when the load changes

before embarking on a longer journey

when the operating conditions change, e.g. off-road driving

when driving at over 250 km/h

Adjust the tyre pressure, if necessary.

HIGH OR LOW TYRE PRESSURE CAN:

shorten the service life of the tyres.

cause increased tyre damage.

adversely affect driving characteristics and thus driving safety, e.g. due

to aquaplaning.

WARNING

Risk of accident due to repeated pressure drop in the tyres

The wheels, valves or tyres could be damaged.

Too low a tyre pressure can lead to the tyres bursting.

Examine the tyres for foreign objects.

Check whether the tyre has a puncture or the valve has a leak.

If you are unable to rectify the damage, contact a qualified

specialist workshop.

Information on the recommended tyre pressure for the vehicle's factory-fitted

tyres can be found on the tyre pressure table on the B-pillar of your vehicle

(/page616).

Use a suitable pressure gauge to check the tyre pressure. The outer appear‐

ance of a tyre does not permit any reliable conclusion about the tyre pressure.

G-Class - Owner's Manual

Wheels and tyres Tyre pressure

F465 0034 02

616

You can also check the tyre pressure using the on-board computer

(/page616).

ONLY CORRECT TYRE PRESSURES WHEN THE TYRES ARE COLD. CONDI‐

TIONS FOR COLD TYRES:

The vehicle has been parked with the tyres out of direct sunlight for at

least three hours.

The vehicle has travelled less than 1.6 km.

A rise in the tyre temperature by 10 °C increases the tyre pressure by approx.

10kPa (0.1bar/1.5psi). Take this into account when checking the tyre pres‐

sure of warm tyres.

NOTES ON DRIVING ON SAND

When driving on sand, you can lower the tyre pressure (/page267).

Tyre pressure table

The tyre pressure table is on the B-pillar on the driver's side.

The tyre pressure table shows the recommended tyre pressure for all tyres

approved for this vehicle. The recommended tyre pressures apply for cold

tyres under various operating conditions, i.e. load and/or speed of the vehicle.

If one or more tyre sizes precede a tyre pressure, the tyre pressure information

following is only valid for those tyre sizes.

The load conditions "partially laden" and "fully laden" are defined in the table

for different numbers of passengers and amounts of luggage. The actual num‐

ber of seats may differ from this.

BE SURE TO ALSO PAY ATTENTION TO THE FOLLOWING RELATED TOPIC:

Notes on tyre pressure (/page615)

Tyre pressure monitoring system

FUNCTION OF THE TYRE PRESSURE MONITORING SYSTEM

The system checks the tyre pressure and the temperature of the tyres fitted to

the vehicle by means of a tyre pressure sensor.

The tyre pressure and the tyre temperature are displayed on the driver display.

In the event of significant pressure loss or excessive temperature of the tyres,

you will be warned by display messages (/page769) or the warning light

h on the driver display (/page784).

The tyre pressure monitoring system serves solely as an aid. It is the driver's

responsibility to set the tyre pressure to the recommended cold tyre pressure

suitable for the operating situation.

In most cases, the tyre pressure monitoring system will automatically update

the new reference values after you have changed the tyre pressure. You can,

however, also update the reference values by restarting the tyre pressure

monitoring system manually (/page617).

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.

G-Class - Owner's Manual

Wheels and tyres Wheel change

F465 0034 02

621

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

Wheels and tyres Wheel change
