"MICHELIN LETS THE AIR OUT OF FUTURE TIRE INNOVATION

Michelin announces two fitments for its revolutionary non-pneumatic
Tweel"

"....The company unveiled the first real-world fitments for its

Now they look weird!

Very odd indeed. I wonder what weight difference there is between this
design and a traditional radial pneumatic tyre.

Asking a lot from you I know but if you had actually read the article
instead of just looking at the pictures you might have noticed the bit
that suggested it was within 5% in terms of weight and rolling
resistance and stuff and within 1% for fuel economy calculating
purposes. Not bad for a new technology.

Per-cent-age? Nah, it means nothing to me.

 

On the face of it, much less weight.. Dunno what that would do for bikes
though.

Oh....

 

Vienna is this ever going to stop?

Did NASA ever say what they were using for the mars rover wheels?

Those things look suspisciously similar.

NASA used wire mesh for the wheels. IIRC they would have collapsed if
the rover had been used on Earth.

 

Mrs Jones, surely?

It looks to me like the rim, although flexible, has enough stiffness to
support the vehicle weight, and the spokes at the opposite side are in
tension. So, not that different in principle from an old-fashioned spoked
wheel.

Not that version, but I could visualise a bike version. Remember the
segmented effort with pivoted plates?

 

platypus says...

I remember that one. I think it was in New Scientist or summut. It
looked a bit of a bumpy ride.

 

Nope, Ms Jones
