As fitted to the Supermarine Spitfire Mk.IX through Mk.XIX. The 4 slot wheels in the Tamiya kit are superb, but the soft rubber tyres have a mold parting line that is very difficult to get rid of, plus they have a natural tendency to attract every piece of dirt and lint in the room, and they need to be cleaned frequently. Replacing them with resin wheels cures these problems, plus, it allows you to paint the tyres, and they will not split or crumble years from now. Replaces the inaccurate and oversized wheels in the Pacific Coast Models kits as well.
