Bridgestone’s been working on air-free car tires for a few years, and now they’re bringing the technology to the world of cycling with the Bridgestone Air Free Bicycle Tire. This concept tire uses a series of inner spokes to eliminate the need for inflation. In addition to providing a comfortable ride, the mixture of resins used for the spokes and outer rubbers represent a more efficient use of resources. The tire is currently in testing and could be on the market by 2019.
