As much as I really wanted to love this tool, it takes at least 50 tire changes to learn to be as efficient as the guys in the video. I change tires on my own equipment so maybe 10 tires per year. It will take me a long time to be as efficient as I am with a standard tire bar. If you are a professional tire guy, this is probably a great investment, if you have a small shop and just do a few tires a year, it’s probably not worth the trouble.
