Default re-inventing the wheel for skateboards on loose surfaces

I'm skeptical. Why wouldn't this work for sand rails and WRC cars on gravel?

Because sand rails have paddle tires, and those work better.

I would think these would have problems in a pneumatic configuration where it would be hard to distribute load consistently across a wavy sidewall.

Also I have a hard time believing these are any better than a straight grooved conventional skateboard wheel would be or maybe a "helix" grooved conventional wheel.

The video seems eerily similar to a snake oil infomercial.

This is how that video watched in my head.

Guys i have invented a shape that fits perfectly in a cube, and because of this useless irrelevant piece of information, it is a transportation breakthrough.

I call it the circle


When I rolled it, it rolled. GASP *cut to rolling montage*


The trick is, it leaves a straight line in the sand creating better stability


*Cut to testimonials of people who dont seem to be that knowledgeable or enthused*
What do you think of my invention the "fish wheel"?
Yep thats a circle.


I am a genius, send me your money

This but with wheels made of the same material and same surface area of contact patch, Id like to see a comparison against a conventional wheel with straight grooves to see if his sin wave theory is correct?

That would be incredibly easy to do. And seeing how it's not provided... I wonder what that might mean. Lol
