Goodyear recently showed off a brand new tire at the Geneva Motor Show, the likes of which we've never seen before. It's known as the EfficientGrip Performance with Electric Drive Technology. If that seems like a really long name for a tire, it's not without merit since it's designed for high-tech electric cars that churn out more torque than gasoline-powered cars.
Because electric cars generate instant torque and have their center of gravity much lower than other vehicles due to the location of the heavy battery, electric cars wear their tires out at a faster rate. At this year’s 2018 Geneva Motor Show, Goodyear unveiled a prototype tire that’s dedicated to electric car usage. Goodyear's own testing shows that tires wear out 30% faster than on
“The combination of increasing regulations to reduce emissions, the desire to reduce dependence on fossil fuels, and rapid gains in battery technology is creating an ideal environment for electric vehicles,” stated Chris Delaney, President of Goodyear Europe, Middle East
Another challenge presented is the need for better range, hence decreased rolling resistance.
The EfficientGrip Performance prototype with Electric Drive Technology met these challenges in the following ways (directly from Goodyear):
- Extended Mileage from Innovative Tread Design: The tread’s thinner sipes (small channels) allow for a larger rubber contact patch on 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
extendthe 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.
Goodyear states that the tire will be on European roads in 2019, and we're guessing they'll also make it to the states with the increased prevalence of electric cars. It's
