According to NHK (Japan), this tire features high-performance resin spokes that support vehicle weight and enhance driving comfort. Testing of this tire type began in February on electric vehicles.
Bridgestone further stated that the plastic spokes of this airless tire technology allow for a more flexible design and are easier to recycle compared to conventional tires. The project leader noted that this tire could contribute to a circular society as the tread can be replaced multiple times.
Bridgestone has partnered with electric vehicle company Idemitsu Kosan to test this tire. The CEO of Idemitsu Kosan, Mr. Akira Oishi, commented: “We believe that Bridgestone’s airless tire concept is environmentally friendly. The puncture-proof tire helps reduce the risk of vehicle breakdowns and is expected to enhance utility value for customers.”
Bridgestone’s airless tire aims to eliminate the need for tire management. Conventional tires are inflated with high-pressure air, functioning like springs to support vehicle weight and absorb impacts from the road. Improper pressure or under-inflated tires can cause issues during driving.
Another Japanese tire manufacturer, Sumitomo Rubber, is also developing a real-time data system for drivers regarding the condition of car tires. This system can determine tire pressure, wear, and other conditions even while the vehicle is in motion.
Sumitomo Rubber plans to commercialize this system starting in fiscal year 2024. The company hopes that eventually, the data will be accessible remotely when used for self-driving vehicles. Japanese officials believe this technology could enhance the safety of autonomous vehicles.
