Read that article a couple of days ago, it occurred to me that there are no sidewalls on these airless "tyres" that would prevent stones or other debris getting in amongst the multitude of spokes. As can be seen in pics the spokes flex a bit just like the sidewalls of proper tyres, what is going to happen as they flex against a stone/hard debris? Can foresee several spoke failures due to wear. Not exactly impossible on our crappy roads. Another consideration is the "tyre" being out of balance with a stone jammed inside.
That was my first thought. Fine on a swept surface. Back to the drawing board.
They are obsessed with gravelling the roads around here, and I shudder at the thought. Not to mention when the bod from village uses the strimmer to cut the grass and invariably my car get the brunt of the grass cuttings. Life would be too short trying to clean that shit and stop moss forming on the inside. Wonder if there is any testing with small mammals too?
