This treaded tire was fitted to Australian Mk. V Spitfires, and any other Spitfire with 5 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 Spitfire model apart. Designed for the Hasegawa and Hobby Boss Spitfire V kits.
