Get Wheels and tires -> Winter operation Guide for Mercedes G Class SUV Third Generation (1990-2018)

Marking : shows the tread wear indicator

(TWI). The arrow indicates the placement of

the tire tread.

Do not drive with tires which have too little

tread depth. tire traction on wet road surfaces

decreases significantly when the tread depth

is less than

in (3 mm).

Treadwear indicators (TWI) are required by

law. Six indicators are positioned over the tire

tread. They are visible once the tread depth

is approximately

in (1.6 mm). If this is the

case, the tire is so worn that it must be

replaced.

The recommended tread depth for summer

tires is at least

in (3 mm). The

recommended tread depth for winter tires is

at least

in (4 mm).

Selecting, mounting and replacing

tires

Only mount tires and wheels of the same

type and make.

Only mount approved tires of the correct

size onto the wheels.

Tires are supplied with a protective layer

from the factory. Break in new tires at

moderate speeds for the first 60 miles

(100 km). They only reach their full

performance after this distance.

Do not drive with tires which have too little

tread depth, as this significantly reduces

the traction on wet roads (hydroplaning).

Replace the tires after six years at the

latest, regardless of wear. This also applies

to the spare wheel.

Winter operation

General notes

Have your vehicle winterproofed at a qualified

specialist workshop at the onset of winter.

Observe the notes in the "Changing a wheel"

section (Y page 334).

Driving with summer tires

At temperatures below 45 ‡(+7 †), summer

tires lose elasticity significantly, and

therefore traction and braking power as well.

Change the tires on your vehicle to

M+S tires. Using summer tires at very cold

temperatures could cause cracks to form,

thereby damaging the tires permanently.

Mercedes-Benz cannot accept responsibility

for this type of damage.

M+S tires

WARNING

M+S tires with a tire tread depth of less than

ã in (4 mm) are not suitable for use in winter

and do not provide sufficient traction. There

is a risk of an accident.

M+S tires with a tread depth of less than ã

in (4 mm) must be replaced immediately.

WARNING

The spare wheel and M+S tires have different

tire characteristics. Driving characteristics

can be severely impaired when you mount the

spare wheel. There is a risk of an accident.

You should therefore adapt your driving style

and drive carefully. Have the spare wheel

Winter operation

Wheels and tires

replaced with a new wheel with an M+S tire

at the nearest qualified specialist workshop.

At temperatures below 45 ‡(+7 †), use all-

season tires or winter tires. Both types of tire

are identified by the M+S marking.

Not all tires with the M+S marking provide the

driving characteristics of winter tires. In

addition to the M+S marking, winter tires also

have the i snowflake symbol on the tire

wall. Tires with this marking fulfill the

requirements of the Rubber Manufacturers

Association (RMA) and the Rubber

Association of Canada (RAC) regarding snow

traction, and were specially developed for

driving on snow. Only these tires will allow

driving safety systems such as ABS and

ESP

to function optimally in winter, since

these tires have been designed specifically

for driving on snow.

Use M+S tires of the same make and tread on

all wheels to maintain safe handling

characteristics.

Always observe the maximum permissible

speed specified for the M+S tires you have

mounted.

When you have mounted the M+S tires:

Check the tire pressures (Y page 316).

Restart the tire pressure monitor

(Y page 321).

You can obtain information about winter

tires that have been approved by

Mercedes-Benz especially for your vehicle

at any Mercedes-Benz Service center.

For further information about tires, see

(Y page 340).

Snow chains

Information about the use of snow chain

compatible AMG winter tires is applicable

for AMG tires. Use of snow chains is only

permissible with these tires.

On some tire sizes there is not enough

space for snow chains. To avoid damage to

the vehicle or tires, observe the "Wheel and

tire combinations" section under "Tires and

wheels".

If snow chains are mounted on the front

wheels, the snow chains could grind

against the bodywork or components of the

chassis. This could result in damage to the

vehicle or the tires.

For safety reasons, Mercedes-Benz

recommends that you only use snow chains

that have been specially approved for your

vehicle by Mercedes-Benz, or are of a

corresponding standard of quality.

Only use snow chains when driving on

roads completely covered by snow.

Remove the snow chains as soon as

possible when you come to a road that is

not snow-covered.

Local regulations may restrict the use of

snow chains. Observe the appropriate

regulations if you wish to mount snow

chains.

Do not exceed the maximum permissible

speed of 30 mph (50 km/h).

If you intend to mount snow chains, please

bear the following points in mind:

Snow chains cannot be mounted on all

wheel/tire combinations (Y page 338).

Mount snow chains only in pairs and only

on the rear wheels. Observe the

manufacturer's mounting instructions.

You can deactivate ESP

(Y page 62)

when pulling away with snow chains

installed. You can thereby allow the wheels

to spin in a controlled manner, achieving an

increased driving force (cutting action).

Important safety notes

WARNING

Underinflated or overinflated tires pose the

following risks:

the tires may burst, especially as the load

and vehicle speed increase.

the tires may wear excessively and/or

unevenly, which may greatly impair tire

traction.

the driving characteristics, as well as

steering and braking, may be greatly

impaired.

There is a risk of an accident.

Follow recommended tire inflation pressures

and check the pressure of all the tires

including the spare wheel:

monthly, at least

if the load changes

before beginning a long journey

under different operating conditions, e.g.

off-road driving

If necessary, correct the tire pressure.

The specifications on the sample Tire and

Loading Information placard and tire

pressure tables are examples. Tire

pressure specifications are vehicle-specific

and may deviate from the data shown here.

The tire pressure specifications that are

valid for your vehicle can be found on the

Tire and Loading Information placard and

tire pressure table on the vehicle.

General notes

The recommended tire pressures for the tires

mounted at the factory can be found on the

labels described here.

Operation with a trailer: the applicable

value for the rear tires is the maximum tire

pressure value stated in the table inside the

fuel filler flap.

Further information on tire pressures can be

obtained at a qualified specialist workshop.

Tire and Loading Information placard

Recommended tire pressures

The Tire and Loading Information placard is

on the B-pillar on the driver's side

(Y page 322).

The Tire and Loading Information placard

contains the recommended tire pressures for

cold tires. The recommended tire pressures

are valid for the maximum permissible load

and up to the maximum permissible vehicle

speed.

Tire pressure table

Example: tire pressure table for all tires permitted

for this vehicle by the factory

The tire pressure table is on the inside of the

fuel filler flap.

The tire pressure table contains the

recommended pressures for cold tires for

various operating conditions, i.e. differing

load and speed conditions.
