Electric vehicle tread development
by Steven K. Henning, TotalEnergies Cray Valley.
Developing tire tread formulations for electric vehicles (EVs) presents a unique challenge. Instantaneous high torque and vehicle dynamics demand traction performance, while owner expectations for battery life and range highlight the need for very low rolling resistance compounds. In addition, vehicle weight and new environmental pressures increase the need for improved durability and abrasion resistance. Silane-terminated polybutadiene resins developed by Cray Valley are functional additives designed to help manage the new EV tire performance balance.
