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.
I want some :icon28:

tweel is soooo two years ago.
next thing you'll find that year old revolutionary suspension made by bose and sing its praises from the rooftop.

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.

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.

I remember this too. It sounds like a great idea, but it been talked about for so long I'm wondering what the hold up is.

Are you kidding? Quantum computers are so close to coming out it's going to be my next computer purchase.

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

But its not two years ago

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.

how do they hold out in -40c to -50c?

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).

thats neat.
i find the hug design/structure very interesting

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.

Once the rubber gets old, I wonder if it will be prone to cracking?

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..

they will be useless for those of us that like Big Break upgrades...
but other then that, its an interesting thing, and it might have a market.. allthough i dont think it will be mainstream

i can see someone slamming down the accelerater and the tyre wraping round itself

LOL, I thought the same thing when I saw them. Surely they've thought to test that though.

wouldn't centrifigul (sp?) force prevent that from happening?
Posted: Tue Jan 24, 2006 2:01 am
by AmIdYfReAk
No, Not if the vforce is great enough..
take a look at the Slicks on Rail car's... when they are launching off of the line, they Fold within them self's due to the force.
these will do the same under high force, But again, i think that they would be beter suited as a.. city.. kinda tire

depends on friction or someshit i guess
same can be said if you slam the brakes though, can see it going completely flat on one side
