Tyres - air pressure

Updated 7/23/2018

Tyres can have different air pressures which are measured in bar.

Check the air pressure in the tyres

The tyre pressures must be checked every month.

This also applies to the car's spare wheel.

  • Tyre pressure for the car's recommended tyre dimension
  • ECO pressure

    ECO pressure results in improved fuel economy.

  • Spare wheel tyre pressure (Temporary Spare)

Note

  • Check the tyre pressure when the tyres are cold. "Cold tyres" means that the tyres are at the same temperature as the outdoor temperature. The tyres will heat up and the tyre pressures will increase after driving for a few kilometres.
  • Tyre pressures which are too low will increase fuel consumption, reduce tyre service life and impair the car's handling. Driving with tyre pressures which are too low may lead to the tyres overheating and sustaining damage. Tyre pressures affect ride comfort, road noise and steering.
  • Tyre pressure decreases over time, this is a natural phenomenon. Tyre pressure also varies depending on ambient temperature.

Tyre pressure label

The tyre pressure label on the driver's side door pillar (between frame and rear door) shows which pressures the tyres should have at different loads and speed conditions. This is also specified in the tyre pressure table, see Tyres - approved tyre pressures.

Fuel economy, ECO pressure

In order to obtain optimum fuel economy at speeds below 160 km/h an ECO pressure is recommended (applies to both full and light load), see Tyres - approved tyre pressures.
