An American film production company needed three different tanks to produce a World War ll film. Original tanks are not available, they are either in possession of collectors or museums and so prototypes had to be developed that appeared as authentic as possible. For a film production over several days and at different locations, the tanks had to be stable, easy to transport and quickly assembled. Not only the weight and easy handling for assembly played a role in the selection of the wheels, but also the tread and the wheel centre. As the wheels are used on a chaindrive, the tread should have a very good floor preservation, low-noise operation and ensure a high operational comfort. The wheel centre should be resistant to dirt, shocks and impacts to use the tanks on different places with different floors.
