Tweel, the airless Tire/Wheel

If you hate to change flat tires here is a new tire for you.

“Michelin’s Tweel is in production and available as an enhancement for future iBOTâ„¢ mobility systems. Invented by Dean Kamen, the iBOTâ„¢ mobility device has the ability to climb stairs and navigate uneven terrain, offering mobility freedom impossible with traditional wheelchairs. Additionally, Segway LLC’s Concept Centaur, a prototype that applies self-balancing technology to a four-wheel device, has also been equipped with Tweel to increase its performance potential.”
