tweel

In addition to the tweel's benefits, you also don't have anyone even notice you're using something different.

So you'd really need to compare a specific model tire against another specific model tweel in tests to know.

How do you repair a tweel thats received curb strike damage or a sharp object?

They were around years ago; Michelin's first tweel was developed in 2004.

Basically I'm imagining something that looks like a regular tire, but inside has the tweel.

For two tires with equal interior volume, the rolling resistance of a tweel will be much much greater than the rolling resistance of a normal tire.

I'm a little surprised the tweel concept never took off or other alternatives.

I seriously doubt Michelin's tweel is anywhere close to that 5.5 kg/T mark.

The authors of that paper did not intend to mislead -- this paper was published in 2011, likely written in 2010, only a handful of years after Michelin's unveiling of their gen 1 tweel design.

But the authors had a secondary purpose driven by 'hype', almost, you could even call it click-bait: they wanted to make the tweel exciting so that other researchers would get interested in it and continue the work.

One way to do that is by showing, from a materials perspective, that it is theoretically possible to design a tweel with a low rolling resistance, and given that, it's possible that tweels will be better for the environment over the full-lifecycle, including manufacturing and materials.

The Michelin "Tweel" IP was actually acquired when Michelin bought BF Goodrich 31 years ago.

I feel like I heard about the "Tweel" in the 90s in Popular Mechanics, and occasionally since then.

Michelin has been selling these under the "Tweel" name[0] for skid steers, commercial lawn mowers, and other mid-sized wheeled equipment for several years now.

These high levels of "tire noise" are the main hold up for consumer applications as the tweel has caught on in low-speed applications when durability outweighs cost considerations.

I live in Canada in a small town with a fairly large (per capita) Lebanese population (Tweel, Haddad, Rashed, Jabour).

Supposedly, they improve the handling and ride of the equipment since the Tweel's internal structure flexes more than an air-filled tire and therefore adds more of a suspension to the tractor.

So I guess the question is how does 0.6% fuel economy loss on average for current tires compare to the loss in efficiency for using a Tweel, but according to some data from Michelin here[2], it looks like they're actually projecting them to be more efficient than current tires?
