Tokyo, Japan – Bridgestone has developed an airless, non-pneumatic concept tire that it said could prove to be a viable and more environmentally-friendly alternative to conventional tires in the future.

Previous non-pneumatic concept tires have been impractical for the mass market, but Bridgestone said it has developed the technology with the aim of practical implementation.

The tire uses a unique structure of spokes stretching along the inner sides of the tires to support the weight of the vehicle, with no need to periodically refill the tires with air and no fear of puncture. The spoke structure is made from reusable thermoplastic resin and, along with the rubber in the tread portion, the materials used in the tires are 100 per cent recyclable.
