In 1962, my father was Chief Mechanic on an Indy 500 racing team. He brought home two hammers used for changing tires - knockoff style in those days. I used one of these as an inspiration for this animation.
Critics will note that the tires are dirt track and not pavement, so there is a mismatch of sorts. However, we used those hammers later on in midget racing. Aluminum handle, brass head, very effective tool.
