Tyres - air pressure

Updated 06/08/2023

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.

Tyre pressure for the car's recommended tyre dimension.
ECO pressure1.

Check the tyre pressure on cold tyres. "Cold tyres" means the tyres are the same temperature as the ambient temperature. After several few kilometres of driving, the tyres warm up and the pressure increases.

Inadequate tyre pressure increases fuel consumption, shortens tyre lifespan and impairs the car's driving characteristics. Driving on tyres with tyre pressure that is too low could result in the tyres overheating and being damaged. Tyre pressure affects travelling comfort, road noise and driving characteristics.

Note

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

When carrying a light load (max. 3 people) and at speeds of up to 160 km/h (100 mph), the ECO pressure can be selected to give the best possible fuel economy. If the best possible noise and travelling comfort conditions are sought, the lower comfort pressures are recommended instead.
