There are airless tires,which are much more efficient than conventional

For hundred of years people used for their car pillow from the made in durable rubber air. This technology has proven effective, but company "Miсhelin" put forward a new concept — the airless tire Twеel.



For the first time "Michеlin" said about these tires in 2005-m to year. The name is a combination of the words "tire" and "wheel" (from the English. "tirе" and "whеel"), as in Twеel don't use the usual hub of the wheel. Solid inner bushing attached to the axle, which is surrounded by polyurethane spokes. The strips are shear stretched on the needles, thus forming the outer edge of the tire — the part that has contact with the road. Tensile shear bands on the spokes replace the air pressure in the conventional tire. Further, the shear band is attached protectors. Externally Tweеl similar to large, futuristic Bicycle wheel.



When the tires contact with the road, the spokes compensate for its effect is exactly the same as the air pressure in an ordinary pneumatic tire. The tread and shear bands deform temporarily bending the spokes, and then quickly return to their original shape. Bus Twеel provide the ability to install different spokes of elasticity, which ultimately enhances driving.
