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.
not really that new. anyway, im not too sure how well it works though it seems like its pretty good. i think one of the complaints is that its some what loud but i might me mistake.
yar saw this a while ago...i think here. from what you posted it seems they're even closer to getting these things to a production stage than when they were first unvieled. it'll be cool to see where these things go in the near future.

next thing you'll find that year old revolutionary suspension made by bose and sing its praises from the rooftop.

I'll be sure not to post anything when flying cars, quantum computers, or time travel is achieved because those are all clearly very old technologies.

Are you kidding? Quantum computers are so close to coming out it's going to be my next computer purchase.
[size=85]yea i've too been kind of thinking about maybe a new sig but sort of haven't come to quite a decision yet[/size]

You did of course notice that was last January, not like 2 weeks ago right???

Yea I think I posted the original thread on here. Very cool technology. I don't know if the testing is holding them up, or the manufacturing, but I can't wait to see how they do in the real world.
I'd like to see them do a hard turn, and see how much pressure is put on them it would seem they would possibly break if alot of pressure was put on them sideways.
Road noise is far too loud ATM to be functional. Plus they want to develope some kind of side wall to prevent mud/dirt from accumulating between the spokes, which with enough mud packed in, would defeat the purpose of the tire (think a Jeep going offroad).

any kind of snow/mud build up would also cause the tire to be unbalanced giving your vehicle major shakes. it's still a problem with traditional tires/rims.
they acknowledge all these flaws though and hope to work them out by using the tech on low speed applications first.
i'm all for it. getting away from air filled tires would be a significant advancement in auto's.

I doubt the treadlife would outlast the rubber. I'm not sure if these will stack up like low-profile tires but if they do you're looking at 15k-30k mile tires.
I would have to guess the same... I am curious about evenness of surface pressure, though
edit: and what that would mean for torque, excelleration, etc..
