Dualie

What about using a Dualie instead of 1 rear wheel. That way if one goes flat, you dont drop down to the road and can probably drive to a fix it. Maybe you dont even need the spare tire or inflation stuff, which may offset any extra cost. I imagine one on which you use two smaller sized tires, and each tire would be cheaper, to some degree. Or the two together being a little wider. I dont think it would cost a lot more and would be safer.

How that affects on traction, braking, aerodynamics, etc. ? Maybe you get a little better braking and traction if its a little wider. Anyway, makes me wonder. Could work on all 3 tires.

I don't think that will work for it will put it into the regulatory specs of an automobile. As long as it has 3 wheels, it will be classified in the motorcycle category and thus have less restrictions. But your idea is good. Maybe they can use a run-flat tire which is a tire within a tire. It will probably not have a formal spare tire (I'm speculating) and use a sealant pump like the BMW i3.

Replying to

I considered that a possibility, and certainly don't know the rules. It seems to me that it would be acting as one wheel. So, make it 1 rim with 2 tire parts. That is not a Dualie, at least to me its not. In fact, that was my original thought. I threw the Dualie in since it already exists. To me, it sounds like a good thing for all tires, so put 3 of these on and flat tires are probably not an issue. No spare, no pump except in rare occasions.

I sort of wanted to rims to allow for some thing like keeping more tread on the road in turns by adjusting (leaning). If they want to say its not a single tire, then its a no go. But if this is one rim with two component pieces, built so that each half can adjust... well. That is engineering and far beyond what I know.

I also did think of the airless tire. That is discussed else where in the forum (flat tires I think). There may be air flow issues with that.
