At the 43rd Tokyo International Motor Show in Japan in 2013, the Bridgestone Group exhibited its second-generation “non-pneumatic tiresâ€. This tire has been further improved with a revolutionary new design that enables the tire to have a bearing capacity, environmental performance and driving performance. As a result, Bridgestone’s “non-pneumatic tires†have entered a new phase on the road to practical application.
Bridgestone's “non-pneumatic tires†support loads through specially shaped spokes that radiate from the side of the tire. They have the advantage of eliminating the need for air filling and saving maintenance, not to mention tire bursts. In addition, the material of the side spoke part of the tire is made of thermoplastic resin*1, and all of the rubber including the tire tread part is made of recycled materials, which is advantageous for the effective use of resources. At the same time, superior low rolling resistance performance is achieved through original technology, which can significantly reduce CO2 emissions and achieve a higher level of environmental and safety performance. Through the development of such technologies, Bridgestone always targets “Tire to Tire†and actively promotes the recycling of resources and the expansion of renewable resources.
In the Group's "Environmental Declaration", Bridgestone aims to achieve "a sustainable society for development" and defines the long-term environmental protection activities for the realization of three societies (a symbiotic society, a cyclical society, and a low-carbon society). We will continue to promote various businesses that are conducive to environmental protection. "Non-pneumatic tires" as a tire product that is more environmentally friendly, Bridgestone hopes to achieve practical applications that can be applied to vehicles in a wide range of fields as soon as possible through continuous development.
As the world’s largest tire manufacturer, the Bridgestone Group has long been committed to promoting “recycling and efficient use of resources†and “reduce fuel consumption to reduce CO2 emissions†through sustainable development models in both business and environment. Continue to provide customers with attractive quality products. Bridgestone said that in order to achieve a "sustainable development" society, innovation and R&D of various technologies will continue in the future, making due contributions to a low-carbon and environmentally friendly automobile society.
Second-generation "non-pneumatic tire" technology and performance characteristics:
1. Performance enhancement: bearing performance and driving performance increase
Among the materials of special-shaped spokes, high-performance resin materials with high strength and flexibility can be used. At the same time, in order to reduce the pressure and deformation inside the tire, FEM (Finite Element Analysis) simulation was used when designing the spokes so that the spoke shape was optimized so far. Based on the above development, compared to the first generation, the second-generation "non-pneumatic tires" achieved performance enhancement through the enhancement of tire load capacity and driving performance. ※2. High-speed driving can be achieved even on ultra-compact vehicles*3. Speed: 60km/h).
2. Pursue low rolling resistance performance and reduce CO2 emissions
In the rolling resistance of a tire, the energy loss caused by repeated deformation of the tire during its movement accounts for about 90%. The second-generation “non-pneumatic tiresâ€, while adopting new materials, have successfully reduced the energy loss significantly by simplifying the structure of the tires, enabling them to achieve the same low-rolling as Bridgestone’s inflated energy-saving and eco-friendly tires. Resistance performance also contributes to reducing CO2 emissions.
