We've seen this concept before, even on the NASA moon buggy. Maybe it's getting a bit closer for car use?
I just got an email from my John Deere dealer promoting these:
Here's another application:
And then there is this old promo for car use:

I remember hearing about these several years ago. I don't think they've ever really pursued it for road use though.
I would be very worried about dirt and snow building up inside the Tweel. This would likely hinder performance, and throw the wheel out of balance and cause dangerous shaking on the highway.
I even had snow build up inside one of my Volt wheels this winter and it caused my car to shake until I cleaned it out.
If the accumulation of dirt, mud, and snow was a problem, Michelin would had tested that already, and maybe will either redesign the Tweel with those opening covered, or sell an aftermarket set of plastic covers to prevent the clogging.

I see this type of wheels perfect for EVs because they are lighter and can absorb road shock and noise better than the air-filled radials, in addition to being non-flats. If I had a BEV and could buy the Tweels for it, I will. And I will never get them clogged!
