It's been over a year since we first modified our Harbor Freight manual tire changer, it's held up great but I had an idea to make it even better after almost scratching one of my wheels.

Parts used:
2" ID clamping collar from Amazon: https://a.co/d/fCPthEr

Low friction tape from Amazon: https://a.co/d/1yUl0oD

Duckbill head from Amazon: https://a.co/d/hxRQxzF

2 1/4" exhaust pipe section from Autozone: https://www.autozone.com/emission-con...

1 1/2" U-Bolts from HomeDepot: https://www.homedepot.com/p/Everbilt-...

I found the steel at a local supplier who sells scraps and off-cuts by weight. I highly recommend you shop local for metal and save probably 90% from ordering online.
