For safety reasons, only use tires, wheels

and accessories which have been specially

approved by Mercedes-Benz for your vehicle.

These tires are specially adapted to the con‐

trol systems, such as ABS, ESP^®and

4MATIC, and marked as follows:

Mercedes-AMG vehicles: observe the notes in

the Supplement. Otherwise, you may fail to rec‐

You can ask for information regarding permitted

wheel/tire combinations at an authorized

Mercedes-Benz Center.

Therefore, only use tire types and sizes

approved for your vehicle model.

Observe the tire load rating and speed

rating required for your vehicle.

Certain characteristics, such as handling,

vehicle noise emissions, fuel consumption,

etc. may otherwise be adversely affected.

Furthermore, other tire sizes could result in

the tires rubbing against the body and axle

components when loaded. This could result

in damage to the tire or the vehicle.

Always replace wheels and tires with

those that fulfill the specifications of

the original part.

When replacing wheels, make sure to fit the

Accessory parts that are not approved for your

vehicle by Mercedes-Benz or are not being used

correctly can impair the operating safety.

#

Only use tires, wheels and accessories that

have been checked and recommended by

Mercedes-Benz.

Avoid obstacles or drive particularly

carefully.

Before purchasing and using non-approved

accessories, visit a qualified specialist workshop

and inquire about:

NOTE Damage to electronic component

parts from the use of tire-mounting tools

Vehicles with a tire pressure monitoring

system: Electronic component parts are

located in the wheel. Tire-mounting tools

should not be used in the area of the valve.

This could otherwise damage the electronic

component parts.

R

Suitability

Retreaded tires are neither tested nor recom‐

mended by Mercedes-Benz, since previous

damage cannot always be detected on

retreaded tires.

For this reason driving safety cannot be guar‐

anteed.

WARNING Risk of accident with high

performance tires

#

Have the tires changed at a qualified

specialist workshop only.

The special tire tread in combination with the

optimized tire compound means that the risk

of skidding or hydroplaning on wet roads is

increased.

In addition, the tire grip is greatly reduced at

a low outside temperature and tire running

temperature.

#

Do not use used tires if you have no

information about their previous usage.

NOTE Damage to summer tires at low

ambient temperatures

*

NOTE Possible damage to wheels or tires

when driving over obstacles

*

At low ambient temperatures, tears could

form when driving with summer tires, caus‐

ing permanent damage to the tires.

Large wheels have a lower tire section width.

The lower the tire section width, the greater

is the risk of damage to wheels or tires when

driving over obstacles.

Switch on the ESP^®and adapt your

driving style accordingly.

#

At temperatures below 45 °F (7 °C),

use M+S tires .

#

Use M+S tire at outside temperatures

of less than 10 °C (50 °F).

Wheels and tires 481

R

Observe the following when selecting, installing

and replacing tires:

For M+S tires, only use tires with the same

tread.

Observe the maximum permissible speed for

the M+S tires installed.

If this is below the vehicle's maximum speed,

this must be indicated by an appropriate

label in the driver's field of vision.

R

Only install wheels of the same size on one

axle (left and right).

R

It is only permissible to install a different

wheel size in the event of a flat tire in order

to drive to the specialist workshop.

Only install tires of the correct size onto the

wheels.

Break in new tires at moderate speeds for

the first 60 miles (100 km).

Replace the tires after six years at the latest,

regardless of wear.

WARNING Risk of injury through differ‐

ent wheel sizes

^RWhen replacing with tires that do not fea‐

ture run-flat characteristics: vehicles with

MOExtended tires are not equipped with a

TIREFIT kit at the factory. Equip the vehicle

with a TIREFIT kit after replacing with tires

that do not feature run-flat characteristics,

e.g. winter tires.

^RVehicles with a tire pressure monitoring

system: All installed wheels must be equip‐

ped with functioning sensors for the tire

pressure monitoring system.

Interchanging the front and rear wheels if the

wheels or tires have different dimensions

may severely impair the driving characteris‐

tics.

The wheel brakes or wheel suspension com‐

ponents may also be damaged.

R

At temperatures below 45 °F (7 °C), use win‐

ter tires or all-season tire marked M+S for all

wheels.

Winter tires bearing the i snowflake sym‐

bol in addition to the M+S marking provide

the best possible grip in wintry road condi‐

tions.

tact a qualified specialist workshop.

Notes on storing wheels

R

The wear patterns on the front and rear wheels

differ:

Lug wrench

Alignment bolt

When storing wheels, observe the following

notes:

R

Front wheels wear more on the shoulder of

the tire

The tire-change tool kit is located under the

cargo compartment floor.

R

After removing wheels, store them in a cool,

dry and preferably dark place.

R

Rear wheels wear more at the center of the

tire

R

Protect the tires from contact with oil, grease

or fuel.

Do not drive with tires that have too little tread

depth. This significantly reduces traction on wet

roads (hydroplaning).

Overview of the tire-change tool kit

On vehicles that have the same size front and

rear wheels, rotate the wheels according to the

intervals in the tire manufacturer's warranty

book in your vehicle documents. If this is not

available, rotate the tires every

3,000 to 6,000 miles (5,000 to 10,000 km),

depending on the wear. Ensure that the direction

of rotation is maintained.

Mercedes-AMG vehicles: observe the notes in

the Supplement. Otherwise, you may fail to rec‐

ognize dangers.

Apart from some country-specific variants, vehi‐

cles are not equipped with a tire-change tool kit.

For more information on which tire-change tools

are required and approved for performing a

wheel change on your vehicle, consult a qualified

specialist workshop.
