  Howstuffworks "Introduction to How the Tweel Airless Tire Works"
In this article, we'll look at what the Tweel Airless Tire is, why you would use it in place of traditional tires, some of the problems that may occur with a Tweel Airless Tire and where you might see the Tweel Airless Tire in the future.
When the Tweel is put to the road, the spokes absorb road impacts the same way air pressure does in pneumatic tires.
Michelin reports that “the Tweel prototype… is within five percent of the rolling resistance and mass levels of current pneumatic tires.

 Fast Cool Cars - Airless tires - The Tweel - Michelin
For manufacturers, the Tweel offers an opportunity to reduce the number of parts, eliminating most of the 23 components of a typical new tire as well as the costly air-pressure monitors that will soon be required on new vehicles in the United States.
The Tweel, mounted on a car, is a single unit, though it actually begins as an assembly of four pieces bonded together: the hub, a polyurethane spoke section, a "shear band" surrounding the spokes and the tread band - the rubber layer that wraps around the circumference and touches the pavement.
While the Tweel's hub functions as it would in a normal wheel - a rigid piece that attaches to the axle - the polyurethane spokes are flexible, to help absorb road impacts.

  Michelin | Press Release: MICHELIN LETS THE AIR OUT OF FUTURE TIRE INNOVATION
The heart of Tweel innovation is its deceptively simple looking hub and spoke design that replaces the need for air pressure while delivering performance previously only available from pneumatic tires.
The Tweel prototype, demonstrated on the Audi A4, is within five percent of the rolling resistance and mass levels of current pneumatic tires.
For Michelin, Tweel is a long-term vision that represents the next step in a long path of industry-changing innovations.

 Detroit Auto Show (NAIAS) 2005 - Michelin Debuts Revolutionary Tweel - MSN Autos
Tweel is available as an enhancement to the iBOT mobility device invented by Dean Kaman, creator of the Segway, as an alternative to a traditional wheelchair with the ability to climb stairs and navigate uneven terrain.
Tweel is able to deliver pneumatic-like performance in weight-carrying capacity, ride comfort, and the ability to deal with road hazards.
Tweel uses a flexible wheel and flexible spokes surrounded by a rubber tread to replace the traditional rigid wheel and air-filled tire.

Опытный образец Tweel примерно в двадцать раз легче обычной шины и обладает в двадцать раз меньшим сопротивлением качению.
Чтобы продемонстрировать широту возможных применений новинки, компания создала не только автомобильный вариант Tweel, который опробовала на Audi A4, но и оснастила Tweel-ами экзотические виды транспорта: робототехническую коляску для инвалидов iBOT и внедорожный самобалансирующий скутер Segway Centaur.

The non-pneumatic, hub and spoke Tweel, which resembles a bicycle wheel, consists of a polyurethane inner mated to a ring of rubber that contacts the road.
Tweels for those applications will be produced by Michelin in Greenville, SC, where much of the development for the device is taking place.
The Tweel's inner ring is made of polyurethane and glass-reinforced plastic and is produced in a 1-step process similar to other plastic injection-molding operations.

Michelin Tweel could dramatically change tyre technology Detroit January 10, 2005 Today at the North American International Auto Show, Michelin showcased a potentially disruptive technology with significant ramifications for the future for mobility: an airless, integrated tyre and wheel combination dubbed the TWEEL (i.e.
The first commercial applications of the Tweel will be in lower-speed, lower-weight vehicles such as the iBOT mobility device and Segway's Concept Centaur Designed by Segway-inventor Dean Kamen, the iBOT mobility device has the ability to climb stairs and navigate uneven terrain, offering mobility freedom impossible with traditional wheelchairs.
Tweel enables us to reach levels of performance that quite simply aren't possible with today's conventional pneumatic technology." The most intriguing application may be Michelin's early prototype Tweel fitment for passenger cars.

 Damn Interesting » Inventing the Tweel
The word "Tweel" is a portmanteau of "tire" and "wheel." Michelin's prototypes integrate the tire and wheel into one component, and the use polyurethane spokes in place of the air in a traditional tire.
A tweel's design also seems to be more conducive to "capping," where the tread of the tire is replaced rather than the entire unit.
Tweels are already being produced for use in some lightweight applications such as the iBOT mobility system, a wheelchair-like device which can navigate stairs and uneven terrain.

 The wheel gets reinvented - News - www.smh.com.au
For manufacturers, the Tweel reduces the number of parts, eliminating most of the 23 components of a new tyre as well as the costly air-pressure monitors that will soon be required on new vehicles in the US.
Mounted on a car, the Tweel is a single unit, though it actually begins as an assembly of four pieces bonded together: the hub, a polyurethane spoke section, a "shear band" surrounding the spokes and the tread band - the rubber layer that wraps around the circumference and touches the road.
The Tweels transmit more of the feel of a coarse road surface than customers would tolerate in a production tyre but that is understandable considering the early stage of development.

Michelin TWEEL, a non-pneumatic mobility concept, will increase productivity because it is maintenance-free, puncture-proof, easy to mount and dismount and provides a longer service life than radial tires.
Taken together, these features mean that Michelin TWEEL is expected to deliver performance that exceeds that of inflated tires.
Michelin is currently studying the application of the TWEEL in small, lightweight earthmover vehicles.

The name “Tweel”’ is the contraction in English of “tire” and “wheel”.
To start with, Tweels could be fitted on vehicles with small wheels, such as wheelchairs, thus substantially improving the mobility of disabled people.
As the Tweel is extremely resistant, we are working on a range of other applications including smaller earthmover and military vehicles.

 Tweels? The Future Tire is a Tweel - by Auto Media
Now, Michelin may take air out of the safety equation with their revolutionary new "Tweel," a combination of tire and wheel that rides on rubber permanently attached to flexible spokes fused with a flexible wheel that deforms to absorb shock.
Tweel enables us to reach levels of performance that quite simply aren't possible with today's conventional pneumatic technology." Gettys said the name Tweel was created to represent the fusion of tire and wheel.
The Tweel doesn't look like a conventional tire, you can see through it, but it has some unconventional aspects that are drawing attention from the U.S. military.

The "Tweel" tire/wheel technology presented here by Michelin Co. and the iBot high-rise wheelchair that eventually will ride on Tweel tire/wheels are two examples of apparently non-automotive technologies that could affect the future of automotive transportation.
In brief, the Tweel is a super-strong yet flexible and airless tire/wheel combination designed to provide maximum traction on a variety of surfaces.
In terms of automotive applications, Tweel technology could be applied to common passenger vehicles in 10 to 15 years, according to Edouard Michelin, co-managing partner of the French tire giant.

The Tweel Handler is an amazingly versatile tool that allows truck mechanics to remove, install, rotate and transport single tire-and-wheel assemblies with ease.
The vertical range of conventional wheel dollies is three or four inches, which forces mechanics to hunker down to inspect tires, or use a floor jack to raise the tire up to machines like balancers.
The Tweel™ Handler chassis is U-shaped to allow users to get closer to the work area, with unhindered access to the tire in the cradle.
