Military vehicles and ATVs have been some of the first vehicles to adopt the unorthodox design, but Bridgestone will soon be making a version of its airless tires for use on bicycles.
Airless bike tires aren’t a new idea, you can already get wheels made from a solid rubber composite if you’ll be riding on terrain where the risk of punctures and flats is high.
But Bridgestone’s approach, which replaces the inner tube and a portion of a bicycle wheel’s spokes with thermoplastic resin supports, is better engineered to absorb bumps and provide an overall smoother ride, without ever requiring the rider to have to adjust the air pressure in their tires.
