Community project: BRILLIANT IDEA

[garrettgajewski]

In the past year, there have been multiple beta runs of both the vesc and wiiceiver. Both were created by endless sphere members. I recently brought up a discussion on whether regular or tire wheels were better. What if someone could create a tire type wheel that could go around a regular longboard wheel. The regular longboard wheel would act almost as a bearing or I don't know what you would call it. But anyways, the tire would just clamp around the longboard wheel and you could easily switch between tires or regular longboard wheels. I don't know of this sounds stupid, but I definitely think it sounds practical!

i like the self titled "brilliant" idea!

So most Tires have a bead to hold them onto the rim. How would you secure a tire to a smooth surface like a longboard wheel? As you switch between tire and regular longboard wheel and it wears - how do you adjust attachment for a smaller diameter/worn lb wheel?

Seems simple in theory, but the mechanism to attach seems like the larger challenge!

GL!

I have thought about this concept. (I spend many hours thinking about eboards!)

The main problem is the diameter of the urethane decreases as the tyre wears out. So the attachment would only fit on nicely at the beginning. Then slowly get loose over time.

Also the drive train of a large diameter wheel is completely different to the smaller wheel if you are using the same motor. So you need a different wheel pulley. This complicates the design even further.

Pneumatics for skateboards need high pressure or they are not effecient. High pressure requires a strong structure. I think trying to attach it to a wheel is not going to be strong.

You know it's not that hard to swap wheels around. It is also possible to make the drive train compatible without swapping/changing the motor KV

The thing I realised though, the type of deck you want on an all-terrain board with larger wheels was not the type of deck I wanted on a commuter style deck.

So personally I think the idea is not viable.

I saw a solution over ten years ago in Switzerland, but it was non pneumatic thoug. It was a cnc milled rim that could be split in two parts to replace the rubber tire. Flanges would hold the tire in place clamping it a bit from both sides, so it can't slip off when cornering.
I remember it was insanely expensive, used car tire type rubber, that wears very fast, would give high rolling resistance but super grip. The system with a splitting rim with flanges could work with tiny pneumatic tires as well I think.
