Some old Proline wheels and tires

Hey folks, just dug up these old Proline Champion tires, they seem to be 2 inch diameter for older buggies and they are narrow, so I would think they were suited for HotShot front wheels or the like.
I think they tri-blades are seen everywhere and I have a total of 3 pair, so if you need that retro 80's look, here you go.
