Changing a Wheel
Notes on selecting, installing, and replacing tires
NOTE
Mercedes AMG vehicles
- Observe the notes in the Supplement.
- You could otherwise fail to recognize dangers.
WARNING
Risk of accident due to incorrect wheel and tire dimensions
If wheels and tires of the wrong size are installed, the service brakes or components in the brake system and in the wheel suspension may be damaged.
- Always replace wheels and tires with ones that fulfill the specifications of the original part.For wheels, pay attention to the following:
- Designation
- Type
For tires, pay attention to the following:
- Designation
- Manufacturer
- Type
WARNING
Risk of injury through exceeding the specified tire load-bearing capacity 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 caused by nonapproved tire types and sizes 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 active safety systems, such as ABS, ESP® and 4MATIC, and marked as follows:
- MO = Mercedes-Benz Original
- MOE = Mercedes-Benz Original Extended (run-flat tires only for certain wheels)
- MO1 = Mercedes-Benz Original (only certain AMG tires)
Otherwise, certain properties, such as handling characteristics, vehicle noise emissions, consumption, etc. could 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.\ 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.
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 wheel and tire damage when driving over obstacles Large wheels have a smaller section width. As the section width decreases, the risk of wheels and tires being damaged when driving over obstacles increases.
- Avoid obstacles or drive especially carefully.
- Reduce your speed when driving over curbs, speed bumps, manhole covers, and potholes.
- Avoid particularly high curbs.
NOTE
Possible wheel and tire damage
NOTE
Damage to electronic component parts due to the use of tire-installing tools Vehicles with tire pressure monitoring system: There are electronic component parts in the wheel. If tire installing tools are positioned in the area of the valve, the electronic components could be damaged.
- Tire-installing tools should not be applied in the area of the valve.
- Always have tires changed at a qualified specialist workshop.
NOTE
Damage to summer tires at low ambient temperatures, tears could form when driving with summer tires, causing permanent damage to the tires.
- At temperatures below 45 °F (7 °C) use M+S tires.
Accessory parts that are not approved for your vehicle by Mercedes Benz, or which are not 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 and 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 tires at outside temperatures of less than 50 °F (10 °C).
- Only use the tires for their intended purpose.
- Observe the following when selecting, installing, and replacing tires:
- Furthermore, the use of certain tire types in certain regions and areas of operation can be highly beneficial.
- Only use tires and wheels of the same type(summer tires, winter tires, MO Extended tires) and the same make.
- Only install wheels of the same size (left and right) on each axle.
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. - 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°F (7°C) use winter tires or all-season tires marked i M+S for all wheels. Winter tires 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 tire which is installed.
If the tire’s maximum speed is below that of the vehicle, 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 MO Extended tires are not equipped with a TIRE FIT kit at the factory. Equip the vehicle with a TIRE FIT kit after replacing it 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.
Be sure to also observe the following further related subjects:
- Notes on tire pressure (/ page 446)
- Tire and loading information placard (/ page 451)
- Tire size designation, load-bearing capacity, speed rating, and load index (/ page 458)
- Tire pressure table (/ page 447)
- Notes on the emergency spare wheel(/ page 472)
Notes on rotating wheels
WARNING
Risk of injury through different wheel sizes.
Rotating the front and rear wheels can severely impair driving characteristics. The wheel brakes or suspension components may also be damaged.
- Rotate the front and rear wheels only if the wheels and tires are of the same dimensions.
- Observe the instructions and safety notes on “Changing a wheel” (/ page 462)
The wear patterns on the front and rear wheels differ:
- Front wheels wear more on the tire shoulder
Rear wheels wear more in the center of the tire Do not drive with tires that have too little tread depth. This significantly reduces traction on wet roads (hydroplaning). 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.
Notes on storing wheels
When storing wheels, observe the following notes:
- After removing the wheels, store them in a cool, dry, and preferably dark place.
- Protect the tires from contact with oil, grease, or fuel.
