Goodyear to showcase new tyre technology for electric vehicles

GENEVA, March 7, 2018

Goodyear, a leading tyre maker in the US, will showcase its EfficientGrip Performance with Electric Drive Technology, a prototype tyre for the growing electric vehicle market that will be on the road by 2019 in Europe, during the upcoming 2018 Geneva International Motor Show.

The event will take place from March 8 to March 18, at the Palexpo, Le Grand-Saconnex, Switzerland.

Goodyear testing reveals that traditional tyres can wear out up to 30 per cent faster on electric vehicles due to the powerful, instant torque from electric motors and the additional vehicle weight from heavy battery packs, said a statement.

Chris Delaney, president of Goodyear Europe, Middle East and Africa, said: “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.”

“We are working with automakers to introduce our Electric Drive Technology next year designed to address the unique performance requirements of this growing vehicle segment,” he said.

In addition to tyre durability requirements, automakers are pressing for enhanced rolling resistance on electric vehicles. Increasing range is a high priority for consumers due to an underdeveloped electric recharging infrastructure in most countries. Quiet and comfort from tyres is another consideration as, at low speeds, electric vehicles generate as little as half the amount of noise as traditional vehicles, it said.

To address these challenges, the EfficientGrip Performance prototype with Electric Drive Technology offers these performance solutions:

•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 tyre cavity shape has been optimised 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.

Delaney said: “As a company with a 120-year heritage of delivering innovative products that help change the world of transport, the EfficientGrip Performance prototype with Electric Drive Technology is proof that our company continues to lead on this path of future mobility.” – TradeArabia News Service
