There’s almost no way bare metal gives the same traction as rubber tyres do. They say it does, but I’d need some really solid data to back that up, for all conditions that the average car will face, not just lab controlled perfect conditions. Tarmac, dirt, snow, rain, heat, cold, etc.
Also one thing I don’t see mentioned is noise pollution. As cars go electric, more and more so the main source of noise from cars becomes their tyres. It’s weird but true. Think of a motorway and how loud the sound of all those tyres rolling is. These would have to be quieter than rubber tyres to be viable.
Also there’s no mention of cost or metal fatigue/wear. Rubber tyres are likely much cheaper to produce - even accounting for economies of scale, they use far less exotic materials.
And I’d be curious how long these tyres last vs traditional tyres through use and wear, how their characteristics such as traction change over time, how they handle hitting debris on the road, be it bits of rocks or whatever. The things cars contend with here and there regularly.
So, while this technology is potentially very promising in a hybrid tyre (like the bicycle tyre shown in the article, Vs the full-metal tyre shown), I have my doubts that need quelling before I see it going anywhere in its full metal state for general use. Specialised, maybe.
I’d love to find something that can replace rubber, and importantly be quieter, and maybe this avenue of research can lead to some great results. I just have my doubts that we’re there yet.
Road wear might also be a concern. If it’s similar wear as a traction engine trundling down the road, the wear might make it unsuitable for most roads.
Maybe they could be dipped in some kind of sustainable rubbery stuff, and when that wears down it’s stripped off and re-dipped. Sounds kinda energy hungry but who knows.
Seems exactly what the KickStarter that’s trying to commercialise this to bike tubes is set out to do. Very interesting tech, but their attempt to appeal to reduce rubber waste falls kinda flat (pun intended) when these new tires require “retreading” their rubber rings

Also I feel like the bare metal ones would collect a bunch of mud inside filtering through the gaps and affecting the balance.
Better traction on regolith maybe.
At 3-5 miles per hour too.
How do these handle on asphalt at 75mph; the overwhelming majority use case for Jeeps in the US

Ain’t no short-cuttin’ physics.
Did you just reinvent radial tires and retreads?
I WANT ROYALTIES!!!
