Mercedes-Benz C-Class (W205) 2015 - 2021 Owners Manual / Wheels and tires / Changing a wheel / Notes on selecting, installing and replacing tires

Mercedes-AMG vehicles: observe the notes in the Supplement. Otherwise, you may not recognize dangers.

You can ask for information regarding permitted wheel/tire combinations at an authorized Mercedes-Benz Center.

WARNING Risk of accident due to incorrect dimensions of wheels and tires
If wheels and tires of the wrong size are installed, the wheel brakes or wheel suspension components may be damaged.
  • Always replace wheels and tires with those that fulfill the specifications of the original part.

When replacing wheels, make sure to fit the correct:

  • Designation
  • Model

When replacing tires, make sure to install the correct:

  • Designation
  • Manufacturer
  • Model


WARNING Risk of injury through exceeding the specified tire load rating or the permissible speed rating
Exceeding the specified tire load rating or the permissible speed rating may lead to tire damage and to the tires bursting.
  • Therefore, only use tire types and sizes approved for your vehicle model.
  • Observe the tire load rating and speed rating required for your vehicle.


NOTE Vehicle and tire damage through tire types and sizes that have not been approved
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 control systems, such as ABS, ESP and 4MATIC, and marked as follows:

  • MO = Mercedes-Benz Original
  • MOE = Mercedes-Benz Original Extended (run-flat tire only for certain wheels)
  • MO1 = Mercedes-Benz Original (only certain AMG tires)

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.

Only use tires, wheels and accessories that have been checked and recommended by Mercedes-Benz.


NOTE Risk to driving safety from retreaded tires
Retreaded tires are neither tested nor recommended by Mercedes-Benz, since previous damage cannot always be detected on retreaded tires.

For this reason driving safety cannot be guaranteed.

  • Do not use used tires if you have no information about their previous usage.


NOTE Possible damage to wheels or tires when driving over obstacles
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.

  • Avoid obstacles or drive particularly carefully.


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.

  • Have the tires changed at a qualified specialist workshop only.


NOTE Damage to summer tires at low ambient temperatures
At low ambient temperatures, tears could form when driving with summer tires, causing permanent damage to the tires.
  • At temperatures below 45 ºF (7 ºC), use M+S tires .

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

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

  • Suitability
  • Legal stipulations
  • Factory recommendations
WARNING Risk of accident with high performance tires
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.

  • Switch on the ESP and adapt your driving style accordingly.
  • Use M+S tire at outside temperatures of less than 10 ºC (50 ºF).

Observe the following when selecting, installing and replacing tires:

  • Only use tires and wheels of the same type (summer tires, winter tires, MOExtended tires) and the same make.
  • Only install wheels of the same size on one axle (left and right).

    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.
  • Vehicles with a tire pressure monitoring system: All installed wheels must be equipped with functioning sensors for the tire pressure monitoring system.
  • At temperatures below 45 ºF (7 ºC), use winter tires or all-season tires marked M+S for all wheels.

    Winter tires bearing the snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions.

  • 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.

  • 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.
  • When replacing with tires that do not feature 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.

For more information on wheels and tires, contact a qualified specialist workshop.
