We ensure the technical quality of our products by testing and studying each raw material used in tire manufacture and by continuously improving our rubber compounds. We are actively looking for and testing sustainable raw materials, such as recycled materials.
Our tires undergo several tests to examine the tire’s behavior in a range of conditions as well as its durability and eco-friendliness. Communities, regions, and organizations (such as EU and UN) have all specified standards that a tire must meet before entering the market. The amount of testing is increasing as more tests and more stringent requirements are being put in place.
Our company’s operations are annually audited by our customers, car manufacturers, and the parties behind various standards. The national regulatory authorities on tires and authorities regulating methods and equipment carry out periodic inspections in order to supervise and evaluate Nokian Tyres’ research and work on ensuring the quality and safety of our tires. Furthermore, we use internal controls for ensuring the high quality and compliance of our operations.
We systematically conduct internal audits and management reviews and continuously improve our procedures. Our ability to comply with the regulations and take care of our contractual obligations is also evaluated each year by our customers and partners. Their own audits verify whether our tire manufacturing processes and R&D functions are appropriate. We also carry out other audits at our factories, for instance in connection with our quality, environmental and safety management system.
Regulatory testing for type approval is done within accredited laboratories that are audited regularly. Accreditation according to ISO 17025 ensures that the laboratory conducts the testing with expertise and impartiality.
In addition to our own activities, we supervise the quality of operations and compliance concerning our subcontractors, suppliers and partners.
