30 gallon grease barrell
I have owned a Coats 220 manual tire changer as well as. No-mar pro and a Hammond full auto tire machine . But my favorite low tech solution is. 30 gallon grease barrell with split radiator hose on the rim. I started out with my old scuba weight belt in the bottom to steady the barrell and threw hundreds of old wheel weights in as I changed hundreds of tires. I use two irons and three rim protectors . I made a bead breaker out of square section tubing . I use RU- glide for tire soap. Properly lubed I can mount the first bead totally by hand and close to 3/4 of the second bead. Bought a static balancer for 90.00 and some tire tools like valve core remover and a good pressure gauge. I still have the No-Mar but I use the barrel most often . If you look around you can find free barrels. For me at 5' 10 it is a perfect working height.
Always keep people in your life that charge your battery. Not those that drain it.
