No, they make airbag jacks to do exactly that. Anywhere between 24"
and 36" square, and Steel-Belted so thy reduce the chance of

They'll move a lot of weight when you combine a few hundred PSI and
a generous quantity of SI's for the Ps to work off.

Perfect for when someone has a cement truck land on top of their
car, Dispatch says the Crane will be two hours, and if they want to
get the passengers out while they're still alive they need to make it
move in a hurry - they stack cribbing to fill the gap, stick in the
lift bags, then inflate and "Up she goes!"

And excellent tools they are.
An inner tube, an airbag does not make, though.
