第5回　タイヤの将来像

抄録

The required performances of tires have been changed with the progress of vehicle technology and surrounding environment. The vehicle industry faces the big change of the so-called “CASE”; Connected, Autonomous, Shares/Service, and Electric. The future tire may not be changed drastically compared with a vehicle, but the performances related to the environment such as rolling resistance and tire noise will be more important than before. Considering the environments surrounding tires, future passenger tires may be classified into five categories: i) Inexpensive pneumatic tire; ii) Expensive pneumatic tire with low aspect ratio which is specialized for performances such as run flat, maneuverability, riding comfort, or etc.; iii) Downsized pneumatic tire with high air pressure which drastically improves both RR and tire noise; iv) Air less tire for small and low speed mobility vehicle; v) Intelligent tire.
