I have always just used an old fashioned ratchet-post car-bumper jack beside the post. So easy AND safe. Requires no gasoline.

You should have released some of the air from the tire. That will give the chain a better seat and stabilize the tire. And get the hell away from it.

Also when a chain snaps it goes straight back, a chain will whip, so i see the guy in no danger

If you wrap the chain in the opposite direction can you also use this method to put posts into the ground?

Seems to me a Come-Along Winch would be safer than pulling with a vehicle. You could still use the truck as a base but the Come-Along Winch would offer better control.
