Tires or treads?-What's the best vehicle locomotion method for traversing loose sand?

Factual Questions

What is the best and most efficient mechanical locomotion method for moving across loose sand to insure that you will not get stuck?

Tires, treads or something else?

      • Um, screws? What was that thing with the two screws? Or was that a swamp sort-of thing?

  • Tires would be the best, because you can actually displace more sand than the vehicle weighs. Monster-truck tires would work, but they’re built for far heavier loads than you’d need for a regular car/light truck. Monster trucks will float in water, so they’d potentially float in sand also. If you could construct your own custom tires, you could lighten them up a lot.
  • Metal-tracked vehicles tend to be very heavy and get poor fuel economy/have high maintenance needs.
  • Sno-cats use very wide, lighter rubber treads; I guess they’d sure stay on top of it, but I dunno what kind of problems you might have in sand.

Hovercraft?

Failing that, probably a wheeled vehicle with big, wide, aggressive tread, low pressure tires.

I would look at existing dune buggies. These have been built from the ground up to run well on sand. Refinement of these has gone on for years.

The current formula:
Light weight
High power
plenty of ground clearence
Large paddle type drive wheels

The get around great and take a near deliberate effort to get stuck.

Sandworms.

Oh, wait, never mind.
