This is one of those topics that I like even if it is not a DIY. It is not topical, since it has been talking about this type of airless wheels or non-pneumatic wheels for a few years, I think since 2002 approximately.
If you have never seen a wheel of this style it will impact you especially when you watch some videos and discover what they are capable of withstanding. I leave one for you to enter into matter. It’s from Michelin Tweel wheels.
