pretty cool...the bike would be ok, to much maintenance on the car tires. Couple of scratches, which are inevitable, and they are ruined...

ever seen these?

Subject: New Revolutionary Tires


Radical new tire design by Michelin. The next generation of tires.



They had a pair at the Philadelphia car show. These tires are airless and are scheduled to be out on the market very soon.

The bad news for law enforcement is that spike strips will not work on these tires.

This is what great R&D will do, and just think! of the impact on existing technology:

a... no more air valves

b... no more air compressors at gas stations

c... no more repair kits



These are actual pictures taken in the South Carolina plant of Michelin. It will be awhile before they are available to the automotive industry.

The clear rims are ugly, and those new tires are f'ing hideous.

i like the new tires, supposed to be better for the environment too cause there is actually less rubber.

Those tires are sweet looking when the car is moving, standing still not so much.

no way would I trust those tires

Gah....they look like wagon wheels.

might not have much of a choice soon, they are rumors other tire manufactures are going to copy it once the patent runs out.

Yea, I work at Bridgestone, and I want to go as some of the guys here at R&D what they think about those. They don't look safe at all. Of course I have a slight bias.

I would be very interested to know their thoughts...

I'll ask around to see who works with tires here, because my group is the polymer group.
i.e. the Goo group

Ditto... I just can't see them as being as reliable as a "normal" tire.
Those flexible spokes.... I dunno....

Ok, I asked the guy who I do most of my work for (he's a phD, and knows a lot about the workings of our company, though he doesn't work with tires) if he had heard about them. He said it's a very interesting concept, but there still is a lot to find out about them. He personally doesn't think they'd be able to handle the normal wear of most tires at this point. He thinks the constant depression and pulling that the "twills" will be put through in everyday driving will have a tendency to wear them out pretty quickly(in relation to standard tire wear), and make them susceptible to breaking/tearing/ripping. It all depends on the tension resistance of the rubber, whether or not it could handle such constant strain, especially considering the weight over a long period of time. He also wonders what would happen if you took a plane trip for example, and let the car sit for a couple(3) weeks. When you drove it again upon your return, would there be a noticable depression where the tire had been resting. He said these are all interesting things that will need to be tuned and worked out(if they aren't alread), though the idea is really good. All of this would also depend on the tendency of the drivers, whether you drive fast, slow, make sharp turns, what you drive on regurlarly, and so on. I would not be the one to have those things on my car to test them out long term, lol.

thanks...I remember the days of nylon bias belted tires that would thump like hell untill they got hot if they sat for more than a day or two.

I would think this would be an interesting technology for "working" tires..loaders, graders, tractors and such. Heck, you might even be able to "bolt" on a recap...

damn i like the look of the clear rims...pretty cool to me.

those new tires are ugly as **** though.

I was thinking along the same lines... also, how would temperature changes effect them? cold make it more "brittle"... hot make is softer?
What about in snow?

With my minimal experience with rubber, hot temperature would make them softer(less firm) while cold would make the rubber more stiff. However, the hot temperature shouldn't be a problem, except in regards to rubber that makes contact with the road itself. The cold could present a problem depending on how cold it is and how long. I would be more worried about constant and sudden changes in temperature though, not so much the extremes themselves. As for snow, other than the temperature concerns, it shouldn't affect the "twills" any more than rain or snow affects the wear on a normal tire.
