BridgestoneTests Environmentally-Friendly Airless Tires

Bridgestone are developing an airless concept tire that could prove to be a more environmentally-friendly alternative to conventional pneumatic tires in the future. The tire features a band of rubber tread around of web of thermoplastic spokes that radiate from the center aluminum wheel. The spokes are stiff enough to avoid vibration (which wastes energy), yet soft enough to provide a comfortable ride.
