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?
Shark Wheels - The Wheel Reinvented

Seems interesting

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.

skeptical is right.
they are better because they lay down a sinewave? so what?

Spitfire 58mm park-burners > everything else.

I want to see controlled test. same bearing board rider etc, only changing the wheels.

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

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
