Shark Wheel Reinvents The Wheel, Raises $30K And Counting For Square Skateboard Wheel

"If this technology takes off, it will be interesting if it gets applied to other uses. Could the same technology improve wheels on automobiles, bikes and other devices that have relied too long on the round model?"


A perfect example of thinking inside the box (watch the video). Might make an awesome race tire - fluorescent colors, looks like it's wobbling as it goes round, and could possibly provide even more lateral grip than 'standard' round tires?

How would that have more lateral grip... The contact patch with the ground is significantly reduced.

Sorry - no idea - I didn't invent it - the guy says it has better lateral grip than a std (skate) wheel, so it may scale - or not.

However, I do know many of the current Hi-Perf tires have what is basically parallel treads strips with voids between them - my Nitto NT-05 are like that - perhaps the weird wiggle shape tread has some extra effect.

It would be interesting if there is actually anything applicable to the automotive world. Perhaps even using the concept to figure out a new rotor design?


I expect that a rubber tire filled with air and subject to FAR greater stresses than a skateboard wheel would not produce more grip at all. However, the concept could possibly have application in super low rolling resistance tires.

I don't think you could produce a pressurized rubber+steel tire that shape. This works because skateboard wheels are solid, made with a mold or something similar. ITwould have to be a completely radical type of construction, though if the benefits are that good...
