The photo below shows the wheels in kit form. Four wheel rims, which are two part items, eight photo-etched spokes, one inner and one outer per wheel, hubs, spinners and tyres. An instruction sheet for assembly is also included, although I have to say that the thought Peter has put into them, means that they really are very simple and quick to put together.
The wheels shown are fifteen inch diameter and will be joined very soon by a sixteen inch version. The finishing touch to any model and one that will guarantee to lift it to another level.
