We are talking about jacking up a car with the jack sitting on the tire ! ?
I got a question how safe is this?
Really guys and girls, for five bucks I wouldn't take the chance.
It's to much work that's why God invented the tire changer

I dug up my 1948 copy of "Audel's New Automobile Guide", and read the
section
on tires. It described basically the same procedure, and even had a picture
of
the "breaking the bead by jacking up a car" trick! It also showed a picture
of a bead-breaking tool that sort of looked like a giant can opener.

with tire irons. Trick #1, use a car jack. Bumper jacks are the easiest,
but any will work. Lay the tire and wheel on the ground, put the jack on
the sidewall of the tire as close to the rim as you can, and jack up the
car. I'd suggest jacking up the heaviest car you can. The bead will
finally pop free about the time the car is up in the air. Sometimes
requires jumping up and down on the car as well. Do this on both sides of
the tires.

can use screw drivers, but they are sharp, and have a habit of pinching
tubes if you're using htem, or at least boogering up the bead. Push the
tire around and get the bead down in the center of the rim. This gives you
the room needed to walk the bead up over the rim lip. You want three irons
because you'll hold the bead up with two of the irons, and have the third
working up the newer section. You don't want to work too far out, because
the forces become excessive and this is how you get a tire iron in the
teeth. Work close in, slowly working the bead up and over, and wiggle the
center iron for clearance.

the tire on the center of the tread. Tie it off to form a loop. Insert a
stout stick, and start twisting. As you twist the rope you will crush the
center of the tire down, and press the bead up against the rim progressively
firmer. This helps it seal and retain the air the compressor is blowing in.
However, I'd recommend simply going to a gas station with a peppy air
compressor and just using it.
