Bridgestone Corporation in partnership with Bridgestone Cycle Co., Ltd. applied its “Air Free Concept” to develop airless bike tyres. These revolutionary bike tyres are a tremendous step forward in transforming the conventional bike tyres of today to complementing bikes of tomorrow.
The “Air Free Concept” is a technology that eliminates the need to have air in bike tyres, while strengthening the tyre material to prevent punctures.
What differentiates these bike tyres is their unique structure of spokes along the inner side to support weight and eliminate the need for air. The tyres also uses resins in the spokes and rubbers to use resources more efficiently.
The “Air Free Concept” resin provides high flexibility for design to create proposals for never-before-seen bikes. The airless bike tyres also support Bridgestone Group’s commitment to work towards a more sustainable, universal and eco-friendly mobility opportunities to improve people’s lives.
Back in 2015, when Bridgestone EMIA was first assessed by EcoVadis, the globally-recognised provider of business sustainability ratings, we were awarded a Silver rating and ranked in the top 12 percent of businesses globally that manufacture rubber products.
In 2018, we announced that three of our tyre plants in Spain – Bilbao, Puente San Miguel and Burgos – had begun sourcing 100 per cent of their electricity from renewable sources.
