I'm seeking for the fastest tire change like formula one and see this though this is really fastest tire change after look at the video, it's not. I would agree with this is very fast compare with me, I would spend an hour LOL to change, normally I have never do that
This is quick but not fastest, im tyremechanic myself at same company, and i often do same setup (steel rims and nuts) in about 10-15sec faster, without counting lowering and lifting car, because we do it wastehigh but we use momentum-rod that tightens it to right amount of torque, so it slowers me a bit but after using it car can be lowered and droven away. And I would recommend to do it yourself before underestimating this mechanic, i'll bet you wont be as fast as he is even after 5 tries.
