Not that you’re gonna run out and buy one, but the best tire changing tool ever is the Italian made Semel Baby kart tire changing machine like I have in my race trailer. I bought one from a friend who was selling off a lot of his stuff, so I got it fairly cheap. ($1k) I had a beadbreaker and a Tire Wizz, maybe even one of those straps, now that I know that’s what it was… from the time I started karting. But I struggled trying to change tires that way. I’ve watched people do it by hand in a few seconds, and I’m always amazed by their talents. Unfortunately, that’s not what happens when I try to change tires, and an hour later I walk away tired and exasperated with a set of tires mounted. Now I’m done in 10 minutes!
