Nokian Tyres plc, headquartered in Nokia, Finland, produces tyres for cars, trucks, buses, and heavy-duty equipment. Known for its winter tyres, Nokian is the only tyre manufacturer in the world with its own permanent winter tyre testing facility. The company's Hakkapeliitta brand name is recognised in Finland as a trademark. Nokian Tyres concentrates on the consumer car and vehicle tyre replacement and premium snow tyre markets. The company also produces retreading materials and tyre pressure monitors. It once manufactured bicycle tyres but now licenses the Nokian name on bicycle tyres to another Finnish company. The Vianor retail tyre store chain, which services cars in addition to selling tyres, is owned by Nokian Tyres PLC. The company traces its history to a groundwood pulp mill established in 1865. Car tyre production began in 1932 by Suomen Gummitehdas Oy. A three-company merger formed the Nokia Corporation in 1967; Nokian Tyres Limited was established in 1988 as a joint venture company split from the conglomerate as Nokia Corporation started focusing entirely on the mobile communications business.
