Higher Load cap and lower rolling resistance. Wayne Gerdes – CleanMPG – March 13, 2017 At the 2018 Geneva International Motor Show, Goodyear revealed an all-new design with EfficientGrip Performance with Electric Drive Technology. The prototype tire was designed for the growing electric vehicle market and will be on the road by 2019 in Europe. Goodyear stated that traditional tires can wear out up to 30 percent faster on electric vehicles due to the high instant torque and additional mass. Chris Delaney, President of Goodyear Europe, Middle East and Africa: In addition to tire durability requirements, automakers are requesting even lower rolling resistance for tires they intend to install on future electric vehicles. Goodyear Tire Electric Drive Technology The EfficientGrip Performance prototype with Electric Drive Technology provides the following advantages: Extended Mileage from Innovative Tread Design: The tread’s thinner sipes provide a larger rubber contact to the road surface than traditional radial grooves. With more rubber on the road, the tire can better cope with high levels of torque while maintaining high performance in wet conditions. The tread design also prevents sound waves from entering its grooves, reducing interior and exterior tire noise. High-Load-Carrying Construction: The tire cavity shape has been optimized to support the additional vehicle weight from batteries while maintaining an optimal tread footprint for high performance. Extended Driving Range: The material properties of the tread compound have been tuned for ultra-low rolling resistance to extend the vehicle range while coping with high levels of torque. In addition, the sidewall has been designed to reduce aerodynamic drag and the profile yields less rotating mass, resulting in reduced energy consumption.
