Michelin® Tweel

This is Airless tyre from Michelin®. Michelin thinks it may have discovered the future of tires with its Tweel technology, which doesn't use air and therefore will never go flat.

The flexible spokes are fused with a flexible wheel that deforms to absorb shock and rebound with ''unimaginable ease,'' says Michelin.

The Tweel replaces the conventional air-filled tire and wheel with a band of composite reinforced tread wrapped around a flexible deformable wheel. The deformable part of the wheel looks deceptively simple. A honeycomb style centre supports composite polyurethane spokes that hold the tread. The spokes and hub can flex to absorb road shock and impacts yet can return to their original shape instantly to provide traction again. The flexible design acts like an air filled tire with similar ride and comfort, but with some not so obvious advantages.
