As a redneck bead breaker for field repairs, I use an off-road/farm HyJack and the receiver hitch on my truck.
Put the foot of the jack on top of the tire near the bead. Place the jack’s “saddle” under the hitch and start jacking until the downward pressure on the foot breaks the bead.
Invest in a good set of tire spoons/irons and then work them with a file anmd sandpaper to remove all sharp edges.
Tire lube is your best friend. I had always used dish soap and then on a whim I tried some pro-grade stuff and it changed my life.
Or per onestrout’s comment, a Harbor Freight tire changer pays for itself very quickly if you are willing to change a few sets of tires on your own. I figure I’ve paid for my tire changer 10X over with all the DIY tire changes I’ve done over the years where I would have had to take the tire to a shop. The one downside is you have to have a very solid mounting base which takes up space.
