This treaded tire/tyre was fitted to Australian Mk.VIII Spitfires, and any other Supermarine Spitfire with 4 slot wheels that needed additional traction due to harsh operating conditions. This style of tread was referred to a Z-block, for the distinctive Z shaped tread blocks that wrapped onto the side walls. The tread pattern has been accurately depicted, including the narrow ribs that connected the blocks. A great looking pair of wheels that will set your Supermarine Spitfire model apart. Designed for the Tamiya and Pacific Coast Models Supermarine Spitfire Mk.VIII kits. Pattern by Lee Coll and Roy Sutherland.
