Notes on selecting, fitting and replacing tyres

You can ask for information regarding permitted wheel/tyre combinations at a qualified specialist workshop.

WARNING Risk of accident due to incorrect dimensions of wheels and tyres

If wheels and tyres of the wrong size are used, the wheel brakes or wheel suspension components may become damaged.

Always replace wheels and tyres with those that fulfil the specifications of the original part.

When replacing wheels, make sure to fit the correct:

Designation
Type

When replacing tyres, make sure to fit the correct:

Designation
Manufacturer
Type

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 damage 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 through tyre types and sizes that have not been approved

For safety reasons, only use tyres, wheels and accessories which have been specially approved by Mercedes-Benz for your vehicle.

These tyres have been specially adapted for use with the control systems, such as ABS or ESP®.

Otherwise, certain properties, such as handling characteristics, vehicle noise and consumption 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 Driving safety put at risk by retreaded tyres

Retreaded tyres are not checked or recommended by Mercedes-Benz , as previous damage is not always detected during the retread process.

Driving safety cannot, therefore, be guaranteed.

Do not use used tyres when their previous usage is unknown.

NOTE Damage to electronic component parts through the use of tyre-fitting tools

Vehicles with tyre pressure monitoring system: there are electronic component parts in the wheel. Tyre-fitting tools should not be applied in the area of the valve.

Otherwise, the electronic component parts could be damaged.

Always have tyres changed at a qualified specialist workshop.

Accessories that are not approved for your vehicle by Mercedes-Benz , or are not being used correctly, can impair operating safety.

Before purchasing and using non-approved accessories, visit a qualified specialist workshop and enquire about:

suitability
legal stipulations
factory recommendations

Observe the following points when selecting, fitting and replacing tyres:

Country-specific requirements for tyre approval that define a specific tyre type for your vehicle.
Furthermore, the use of certain tyre types in certain regions and areas of operation can be highly beneficial.
Use only tyres and wheels of the same type, design (summer tyres, winter tyres, all-season tyres) and make.
Only fit wheels of the same size and tread design on one axle (left and right).
It is only permissible to fit a different wheel size to this 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 wheel spacers or brake dust shields is not permitted and results in the invalidation of 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 monitoring system.
At temperatures below 10 °C use winter tyres or all-season tyres with the M+S marking on all wheels.
Winter tyres bearing the 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 permissible speed, this must be indicated in an appropriate label in the driver's field of vision.
Run in new tyres at moderate speeds for the first 100 km.
Replace the tyres after six years at the latest, regardless of wear.
