Thanks for these videos as they helped me enormously. I changed 10 low profile stiff sidewall tyres and, after swearing a bit with the first one, the rest were easy once I got the hang of it.

I have the exact same Harbor Freight tire changer. I paid $35 for it when I bought it. You just spent $115 for a mod on a $35 tool. I'd say it was probably worth it, but hey.....
I will also say that low profile tires are the bane of the universe when it comes to mounting and dismounting them.

You need to get you a strap and you leave that down there with that beep.Breaker push down on one side that it gave you room where you can get that outside edge started up

Going to the tire shop is faster

Dude you have not a clue how to use that tire changer you make it look harder for yourself to dismount the tires! You should watch YouTube videos on how easy it really is 😂
