there was a thread on something like this a couple of years ago.
2x4 wood blocks strapped to the wheel - inexpensive - easy to build.
I went to the post but the youtube is not available anymore.
it was basically the "truck claw" version using 2x4 wood blocks instead
of the steel gizmo.
remember - beach sand is a LOT more unforgiving than mud out in the country.
a low profile such as the Truck Claw could act like a hundred tiny shovels
burying you even deeper.

but use several pieces of wood on each wheel
