Responsibility for human rights and environmental standards



We have set up a complaints procedure that enables employees, business partners and third parties to report human rights and environmental risks or breaches of duty that have occurred in our business area or at one of our direct suppliers.

This whistleblower system enables anonymous, confidential and secure communication. We will investigate every reported tip-off and in particular ensure that the respective whistleblower does not have to fear any reprisals or other disadvantages as a result of using the whistleblowing system. Abuse of the whistleblowing system is excluded.

The complaints procedure and the associated rules of procedure can be accessed via the following link:



Our complaints procedure is a component of our strategy to fulfil the corporate due diligence obligations of the Supply Chain Act (Lieferkettensorgfaltspflichtengesetz, LkSG).

The EU energy label for tyres

The new EU tyre label helps consumers to decide in favour of a higher fuel efficiency class for their tyres. This can contribute to large reductions in running costs and emissions. Enhanced wet grip means greater road safety, and details of external rolling noise contributes to a reduction in traffic noise levels. 

The actual fuel savings and road safety depend heavily on the behaviour of drivers, and in particular on the following:

  • Eco-driving can significantly reduce fuel consumption
  • Tyre pressure needs to be regularly checked to optimise fuel efficiency and wet grip.
  • Stopping distances must always be respected.

Fuel efficiency class

Less rolling noise saves fuel and cuts CO2. This property is assigned to classes A to E.

Wet grip class

Wet grip is assigned to classes A to E. Wet grip is crucial to safe driving. For instance, the difference between class A and class E braking distances is 18 m.

External rolling noise class

The label presents the volume in dB and the class A (quieter), B, or C (louder). The noise emitted by tyres affects the total noise levels emitted by the vehicle.

Snow grip

The snowflake symbol confirms that the snow tested tyre keeps within the 3PMSF limits (type approval).
