What's the real benefit of the Tyre from a manufacturing perspective?
From what I can see and understand, it may need more raw materials to make, may deform when the car is parked for a long time, doesn't have the compression abilities of air. Won't it be noisy too?
I could be completely wrong though.

Looks interesting but I will hold my tongue till it is actually released. They are talking about 2024 at the earliest which is a long way off....

This would also take time to gain acceptance as the infrastructure to install these tyres would need to be different from the current tyre changers.

I'm quite sure this is never going to take off. Lateral, braking, and the dependence on load, all are terminally limiting factors for the design for regular road use. Lunar rover, maybe. In fact, it's a step backwards, maybe a dozen, in what tyres are right now.
Why reinvent the wheel?

I don't feel the technology is usable in its current state.
Think about cornering at speed on these! Scary for sure.

Looking at the prototype I doubt these tires will have good high speed stability. It could be a ground breaking innovation for areas like Military for example. In a combat situation a flat tire could prove disastrous. This is where these Tweel tires could come handy on Military vehicles.

Militaries have been testing them out for quite some time now.

These ones (below), were designed by Michelin themselves in the 2000s -

  • They're already being used in cycles, skateboards, lawnmowers and other heavy vehicles.

Some observations -
  • These tyres (if they ever do get launched) will have side-walls like in the ones you can see above. The initial pics in this thread are probably just for demonstration purposes only.
  • It hardly looks like these concepts will materialize any time soon. All their practical disadvantages would need to be fully corrected & tested before they can be produced in the mass market. Besides, the main advantage that they're pushing here, is the absence from tyre punctures. Tyre quality, over the years, has improved so much that I don't think we are affected by punctures as often as we were before.
  • I was expecting 'flying cars' in the future. And yet, here we are, discussing tires!
  • If these tyres start getting popular, the police won't be needing these anymore -

This would be one of the most fascinating inventions, if it at all becomes a reality. Looks are skeletal, but in a much positive way. I'm however not quite sure about the roads of rural India. But yes, will be hoping to have it here soon. As always, goodness is appreciated.

IMHO, these does not suit for Indian roads especially mud roads.
Can try using for the city roads.
However, we should look for how they are going to address the imbalance cased due to chocking of mud.
