The Air-Free Tire is an airless tire design concept by Bridgestone (video by DigInfo TV). The concept relies on thermoplastic resin spokes to give the tire its shape and flexibility (it is also 100% recyclable). Due to the limited load capacity of the tire, it is intended for use in lightweight carts and personal mobility devices, with use on larger vehicles planned for the future. The tire debuted at this month’s Tokyo Motor Show.
Michelin developed a similar concept, the Tweel, back in 2005.
