Manually changing out a tire on a rim is a royal pain-in-the-ass, and that's probably why you've never seen it done without a machine.
To do it manually, remove the stem, then break both beads with a well-positioned c-clamp, jack, or lever, or by carefully driving over the tire with another vehicle.
With the beads off, use at least two tire irons (and maybe some rags to protect your rim) to work the tire off one side of the rim. Gotta make sure that the other side of the tire is sort of nestled within the rim so that it gives you the most "slack" to work with. Also, a vise grip clamped to the rim can make sure that the tire doesn't slip back while you're prying.
Once you get one side off, you do the other, which is usually easier.
Mounting is the reverse, and only slightly less of a pain in the ass. Also soapy water is highly suggested for all these steps.
To reset the beads, you can manage it with a high-flow air compressor (at a gas station can work), but you may run into occasional problems. Wrapping a ratcheting strap around the circumference of the tire can help. Use soapy water to help the bead slip on too.
If the air compressor doesn't work, you can use the starting fluid explosion trick, but this can be dangerous and is tricky to get right. You risk melting your tire too. It is fun when it works though.
You can do an OK job with balancing by rigging the tire so that it balances like a "plate on a stick" and then seeing which way it tips.
And again, I don't suggest any of this, because it's just not worth it compared to using a machine or getting a shop to do it for you.
I dad did it with a really big Phillips head screwdriver back in the day. I remember helping him when I was a kid. What a pain in the ass. I said why does we just take it to a tire shop? He said good, we will use your money. Of course I was a kid and had no money, haha.
