I'm doin a project on these. I made the image in Illustrator.

I think its an excellent idea. Inherent characteristics as a result of the design will make them less suitable for performance driving, but from a safety standpoint I think the concept is wonderful.

the performance potential is much greater with the absence of the tire pressure variable, no more filling tires with different gasses to try and stabilize the tire pressure under varying temperatures, or premature wear due to improper temperature, or flat due to all kinds of shit. It would also be possible to gradate the compliance of the "tire spokes" outward towards the edges for greater/stiffer shoulder strength. there is much more potential to control where the tire is stuff and just how stiff.


you haven't seen this tire because it would hurt the tire industry, think of the loss of sales if every tire sold or even 50% more(bad alignments) lasted to the bottom of the tread... No more flat tires.

Until that takes place, they would suck ass for performance. And afaik, they're still not able to handle high cornering loads. So as far as the current state of the tweel is concerned, they suck performance-wise and I do no retract my statement.

correct, its not a production tire (it doesn't have much of a chance until the patent runs out) and the current design is not performance oriented, but the performance potential of this design is still far superior to anything that relies on air pressure for structural strength.
 
this is the best part to read from the article.

"Michelin has also found that it can tune Tweel performances independently of each other, which is a significant change from conventional tires. This means that vertical stiffness (which primarily affects ride comfort) and lateral stiffness (which affects handling and cornering) can both be optimized, pushing the performance envelope in these applications and enabling new performances not possible for current inflated tires. The Tweel prototype, demonstrated on the Audi A4, is within five percent of the rolling resistance and mass levels of current pneumatic tires. That translates to within one percent of the fuel economy of the OE fitment. Additionally, Michelin has increased the lateral stiffness by a factor of five, making the prototype unusually responsive in its handling. "
 
....omg jaja read the article man its interesting... Its a flat chunk of rubber on a rim (no air in rubber) hence you can never go flat, tires last a LOT longer but the ride is harsh and hence it hasnt gotten into production. they're developing a flexy type rim that will also have damping characteristics, that and better suspension technology will make this happen.
(also read on the BOSE suspension and how they're creating a sysem that works in face with road frequency and tries to cancel the resonance on normal systems to make it smoother...i think lexus is trying to put this into their production cars)
