These fit the original HotWheels tires. You get 4 wheelsets in this order. You still have to paint these yourself; that goes for everything on Shapeways.com Shown on a HotWheels with clipped stock axles. If you don't want to open the model; you can cut off the plastic wheels, but preserve as much of the stock axles, then trim to fit these. I use washers to space the wheels often. Or use poster putty to pose steering and camber.
