Back in 2013, Bridgestone announced a concept for airless tires for cars called 'Air Free,' as part of a move towards emission reduction and greater use of sustainable materials. Now, Bridgestone has made the concept a reality for bicyclists.
The Air Free Concept introduces tires that do not need to be inflated with air to support weight. Rather than boasting a heavy design, these airless tires have a lightweight form that uses resins in the place of spokes and rubber.
Commercially, these new airless tires for bikes from Bridgestone are set to be on the market as of 2019, offering an easy way for the public to get around urban environments. Until then, these innovative tires from Bridgestone are being tested as part of a few special events in Japan.
