Sumitomo Rubber Develops Tire Aerodynamics Simulation Technology

Sumitomo Rubber has developed Tire Aerodynamics Simulation, a simulation technology for the tire development process. In addition to reducing rolling resistance of tires, it is extremely important to reduce aerodynamic drag around tires in order to improve fuel efficiency (electric power consumption) of EVs. By visualizing the airflow near the tires of a moving vehicle through a proprietary simulation that...
