From Goodyear Press Release
Goodyear offered a sneak peek during the 2018 Geneva International Motor Show of its EfficientGrip Performance with Electric Drive Technology, a prototype tire for the growing electric vehicle market that will be on the road by 2019 in Europe.
Goodyear testing reveals that traditional tires can wear out up to 30% faster on electric vehicles due to the powerful, instant torque from electric motors and the additional vehicle weight from heavy battery packs.
“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,” said Chris Delaney, President of Goodyear Europe, Middle East and Africa. “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.”
In addition to tire 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 tires is another consideration as, at low speeds, electric vehicles generate as little as half the amount of noise as traditional vehicles.
Electric Drive Technology
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 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.
“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 Goodyear continues to lead on this path of future mobility,” Delaney said.
Goodyear demonstrates its intelligent tire prototype on the road
Goodyear showcased the latest advances on its intelligent tire prototype, a complete tire information system that includes a tire, sensors and cloud-based algorithms that all work together to communicate in real-time with fleet operators via a mobile app.
“As shared mobility continues to grow in popularity, we are seeing applications where kilometers driven per vehicle will increase substantially in the years ahead,” said Chris Delaney, President of Goodyear Europe, Middle East and Africa. “For shared fleet operators, proactively managing tire service issues is critical to both the customer experience and the business model.”
The Goodyear intelligent tire prototype allows for continuous connectivity and real-time data sharing, enabling optimal tire usage for safer and more cost-efficient mobility and maximized uptime.
The sensors in Goodyear’s intelligent tire, together with the vehicle and third-party information, provide real-time data to Goodyear’s proprietary algorithms. Thanks to these algorithms, information on tire ID and status - including wear, temperature and pressure - is continuously updated and shared with fleet operators.
“Tire performance and wear information provide a real-time signal for when a tire needs service to extend its life, fuel economy and performance attributes,” Delaney continued. “This kind of proactive maintenance allows fleet operators to precisely identify and resolve tire-related and potential service issues before they happen.”
Shared mobility is continuing to grow based on desires for reduced cost and increased convenience for consumers. In 2015, shared kilometers accounted for 4% of global kilometers traveled. This number is projected to exceed 25% by 2030.¹
“As the face of mobility continues to evolve, so will the needs of consumers and fleet operators,” said Delaney. “Goodyear is anticipating the products, services and experiences that will deliver the mobility that consumers and fleet operators need.”

Goodyear Oxygene, a Concept Tire Designed to Support Cleaner and More Convenient Urban Mobility
Goodyear’s latest concept tire, introduced at the 2018 Geneva International Motor Show, quite literally brings the future of mobility to life as a visionary solution for cleaner, more convenient, safer and more sustainable urban mobility.
The concept, named Oxygene, has a unique structure that features living moss growing within the sidewall. This open structure and the tire’s smart tread design absorb and circulate moisture and water from the road surface, allowing photosynthesis to occur and therefore releasing oxygen into the air.
According to the World Health Organization (WHO) more than 80% of people who live in air pollution-measured urban areas are exposed to air quality levels that exceed WHO limits.¹
“With more than two-thirds of the world population expected to live in cities by 2050, the demands on transport networks in urban environments will increase substantially,” said Chris Delaney, President of Goodyear Europe, Middle East and Africa. “Smarter, greener infrastructure and transport will be crucial in addressing the most pressing challenges of urban mobility and development.”
Inspired by the principles of the circular economy, with emphasis on reducing material waste, emissions, and energy loss, Goodyear’s Oxygene concept is designed to integrate seamlessly into future cityscapes, featuring several performance solutions:
Cleaning the Air We Breathe: Oxygene absorbs moisture from the road through its unique tread and inhales CO2 from the air to feed the moss in its sidewall and release oxygen via photosynthesis. In a city similar in size to greater Paris with about 2.5 million vehicles, this would mean generating nearly 3,000 tons of oxygen and absorbing more than 4,000 tons of carbon dioxide per year.
Recycling Worn Tires: Oxygene features a non-pneumatic construction that is 3D-printed with rubber powder from recycled tires. The lightweight, shock-absorbing structure provides a long-lasting, puncture-free solution intended to extend the life of the tire and minimize service issues, delivering worry-free mobility. Additional safety is ensured by the tire’s open structure, which improves wet grip by helping absorb water from the tread.
Generating its Own Electricity: Oxygene harvests the energy generated during photosynthesis to power its embedded electronics, including onboard sensors, an artificial intelligence processing unit, and a customizable light strip in the tire’s sidewall that switches colors, warning both road users and pedestrians of upcoming maneuvers, such as lane changes or braking.
Communicating at the Speed of Light: Oxygene uses a visible light communications system, or LiFi, for high-capacity mobile connectivity at the speed of light. LiFi enables the tire to connect to the Internet of Things, allowing vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) data exchange, which is critical to smart mobility management systems.
“Like the concept designs Goodyear has presented at Geneva in the past, Oxygene is meant to challenge our thinking and help drive the debate around smart, safe and sustainable future mobility,” Delaney said. “By contributing in this way to cleaner air generation, the tire could help enhance quality of life and health for city-dwellers.”
