The Sak Co. Production & Sales (joint venture) has been involved in the tire business for over 30 years. It was established in Opole, Poland in 1964 - retreading tires, selling them and offering other services associated with tires to the local public.

During the years, the company has made progress and expanded. It is the owner of two warehouses - located in Opole and Gliwice, three retail tire outlets (Opole, Gliwice and Strzelce Opolskie) and a bonded warehouse for tires ready to be sold in the country or reexported out. In 1995, the Sak Co. became the exclusive importer for Mastercraft tires from Cooper Tire & Rubber Co. from the USA.

Since then the Sak Co. has been working hard to develop the Mastercraft brand on the Polish market in the 4x4 segment.
