WARNING
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.
Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

The recommended tire pressures for the tires mounted at the factory can be found on the labels described here.

Option 1) Tire and Loading Information placard on the B-pillar on the driver's side of the vehicle (Y page 362).

The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed.

The specifications given on the following Tire and Loading Information placard are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressures applicable to your vehicle can be found on the Tire and Loading Information placard on your vehicle.

1 Recommended tire pressures

Option 2) Tire pressure table 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.

Specifications shown in the examples of tire pressure tables are for illustration purposes only. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. Tire pressure specifications applicable to your vehicle are located in your vehicle's tire pressure table.

Example: tire pressure table for all tires approved ex-works for this vehicle

If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of passengers and amounts of luggage. The actual number of seats may differ.

Example: tire pressure table with tire dimensions

Some tire pressure tables show only the rim diameters instead of the full tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire sidewall.

If the tire pressures have been set to the lower values for lighter loads and/or lower road speeds, the pressures should be reset to the higher values:
- if you want to drive with an increased load and/or
- if you want to drive at higher road speeds.

The tire pressures for increased loads and/or higher road speeds, shown in the tire pressure table, may have a negative effect on driving comfort.

For trailer towing, adjust the tire pressure of the rear tires to the maximum tire pressure value stated on the table inside the fuel filler flap.

Option 3) The tire pressure for the emergency/collapsible spare wheel (depending on vehicle equipment) can be found:
- printed in yellow on the rim of the emergency/collapsible spare wheel
- in the "Wheel and tire combinations" section in this manual
- on the Tire and Loading Information placard on the B-pillar on the driver's side.

If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure.

For further information, consult a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
