Innovation through technologies

New tire development is a highly complex process which brings together a host of specialist expertise including tire pattern design, material selection, in-depth analysis, prototyping, testing, tire mold manufacture and mass production.
At our Goodyear Innovation Centers, we encourage teams to push the boundaries of tire technologies. To seize the opportunity to develop sophisticated tires that offer drivers the ultimate performance through excellent handling, grip and braking in a wide variety of road and weather conditions.

Our environmental impact reduction strategy begins with the optimization of materials. The raw materials we use are constantly evaluated to review their characteristics, energy composition, social and regulatory requirements, and possible alternatives.

BioIsoprene™

Goodyear and DuPont Industrial Biosciences are working together to develop BioIsoprene™, a revolutionary bio-based alternative for petroleum-derived isoprene. The development will help reduce the tire and rubber industry’s dependence on products derived from oil. To date the collaboration has produced a prototype tire made with BioIsoprene™ monomer.

Soybean tire

Goodyear researchers at the company’s Innovation Center here have found in their tests that using soybean oil in tires can potentially increase tread life by 10 percent and reduce the tiremaker’s use of petroleum-based oil by up to twenty six million liters each year.

This development could help consumers and the environment by reducing the amount of petroleum-based oil used in tires, while at the same time, extending tread life. The company found that rubber compounds made with soybean oil blend more easily with the silica used in building tires. This can improve plant efficiency and reduce energy consumption and greenhouse gas emissions.

Rice Husk Ash

Let’s move towards sustainable future mobility with renewable materials

Here at Goodyear, we continuously innovate to create a better future and aim to meet the highest standards in road safety and sustainability for now and in the future.

goodyear-innovation-rice-husk

Rice husk waste once headed for landfills is now helping Goodyear fuel-efficient tires. Goodyear will start utilizing ash left over from the burning of rice husks to produce electricity as an environmentally friendly source of silica for use in its tires.

The company has tested silica derived from rice husk ash over the past two years at its Innovation Center and found its impact on tire performance to be equal to traditional sources.

Foam-in-Tire technology for electrical vehicles

Year after year, cars become quieter and quieter, even more so with the increasingly popular electric and hybrid cars. That however means that the noise made by tires becomes more noticeable inside the car.

At Goodyear, we write innovation with a capital ‘I’ and recently we looked at how we could innovate to make a tire quieter, without having any impact on any of the other key performances of a tire like rolling resistance, braking, handling, tread wear on all the other performances that are key to keep the tire on the road….We call this technology Foam-In-Tire technology.

Goodyear Presents New Tire Technology Designed to Advance the Performance of Electric Vehicles

The EfficientGrip Performance prototype with Electric Drive Technology is Goodyear’s latest step in developing tires that meet the specific demands of Electric Vehicles

eagle_360_urban

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. Therefore, Goodyear is working with automakers to introduce the EfficientGrip Performance with Electric Drive Technology in 2019 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.

Goodyear intelligent tire prototype is designed to ensure optimal connectivity between tire and fleet operators

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 shared mobility continues to grow in popularity, kilometers driven per vehicle will increase substantially in the years ahead. For shared fleet operators, proactively managing tire service issues is critical to both the customer experience and the business model.

eagle_360_urban

The Goodyear intelligent tire prototype, consists of a complete tire information system that includes a tire, sensors and cloud-based algorithms and that all work together to communicate in real-time with fleet operators via a mobile app. It 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. This kind of proactive maintenance allows fleet operators to precisely identify and resolve tire-related and potential service issues before they happen. 

As the face of mobility continues to evolve, so will the needs of consumers and fleet operators. 

Goodyear is anticipating the products, services and experiences that will deliver the mobility that consumers and fleet operators need.

RFID Radio-Frequency Identification

Technologies such as RFID (Radio-Frequency Identification) Technology allow tires to become increasingly intelligent through the use of embedded electronics. Tires can now be identified using a microchip built into the tire which is programmed with a unique code that enables an automatic reading of the type and size of tire as well as its unique identity number.

Air Maintenance Technology

Maintaining correct tire pressure is essential for optimal performance of a tire. Properly inflated tires will improve fuel efficiency, so they can reduce fuel consumption by up to 5% and increase mileage by up to 25%. And that's not all. The correct tire pressure will result in reduced CO2 emissions while also minimizing the wear on the tread. Far too many drivers fail to check the air pressure in their tyres on a regular basis but the good news is that with Goodyear’s new Air Maintenance Technology (AMT), drivers never have to check or correct their tires’ air pressure again. The Air Maintenance Technology keeps optimal safety performance, ensures improved mileage by 25% and saves money with 5% better fuel efficiency. Goodyear is justly proud that its Air Maintenance Technology was named one of Time magazine’s “Best Inventions of the Year 2012”.

RunFlat technology

A punctured tire is both inconvenient and dangerous. With RunOnFlat tires, a puncture - regardless of size or location - won’t leave motorists stranded. Goodyear RunOnFlat tires are specially designed with stronger sidewalls than conventional tires, which enable the tire to hold its shape and support the full weight of the vehicle – even without any air pressure. RunOnFlat tires can keep going for up to at least 80km at maximum up to 80km/h at very low or zero inflation, allowing the driver to reach a safe location and get the tire repaired or changed. Unless otherwise specified in the car owner's manual, a Goodyear or Dunlop RunOnFlat tire can be repaired by a qualified tire professional after a thorough inspection and analysis of the tire history. In case of doubt the tire should not be repaired. The professional repairing the tire is in any case responsible for his repair work.

goodyear-innovation-suv-concept-tire

The future of mobility is a key global challenge and Goodyear is leading the development of a host of innnovative technologies that will help to shape the transport of tomorrow. Today, our cars talk to us, letting us know when there’s a vehicle in our blind spot or suggesting a route to avoid traffic. Tomorrow, the components themselves will be connected. The tire will ‘talk’ to the vehicle.

Goodyear Oxygene, a Concept Tire Designed to Support Cleaner and More Convenient Urban Mobility

Goodyear’s Oxygene concept envisions a driving solution that improves air quality

Goodyear Oxygene

The concept, named Oxygene, brings the future of mobility to life as a visionary solution for cleaner, more convenient, safer and more sustainable urban mobility. 

It 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.

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.

Oxygene is meant to challenge our thinking and help drive the debate around smart, safe and sustainable future mobility. 

By contributing in this way to cleaner air generation, the tire could help enhance quality of life and health for city-dwellers.

Goodyear Eagle 360 Urban: a Concept Tire Powered by Artificial Intelligence

The tire of the future will be able to sense, decide, transform and interact

Eagle 360 Urban
eagle_360_urban

The Eagle 360 Urban is Goodyear’s long-term vision for future smart, connected tires. In an evolving mobility ecosystem defined by the transition to driverless vehicles and shared mobility in urban centers, Goodyear aims to revolutionize the interaction between tires, vehicles and their surroundings. This 3-D printed sphere is the first concept tire to be powered by Artificial Intelligence and able to sense, decide, transform and interact.

A revolution will take place at the intersection of autonomy, mobility and connectivity. As this unfolds, tire technology will be even more important than it is today. To safely navigate their surroundings, the autonomous vehicles of the future will need to learn to cope with the millions of possible unknowns we face in every day driving scenarios. To do so they will need access to data and the ability to learn and adapt.

Powered by Artificial Intelligence, Goodyear is giving the concept tire a ‘brain’. Combined with a bionic skin and morphing tread, the Eagle 360 Urban has the ability to put knowledge into practice. The tire will become part of the vehicle’s ‘nervous system’ and the connected world of the Internet of Things. That way, it is ready to rapidly adapt to changing circumstances, as well as the evolving needs of Mobility as a Service (MaaS) for fleets and their users.

Goodyear’s Eagle 360 Urban features bionic skin with a sensor network that allows the concept tire to check on its own status and gather information on its environment, including the road surface. Via connectivity with other vehicles as well as infrastructure, traffic and mobility management systems, the Eagle 360 Urban also captures information on its surroundings in real-time.

By combining these sources of information and processing them instantaneously using neural networks trained with deep learning algorithms, the Eagle 360 Urban decides the most appropriate course of action. And, powered by Artificial Intelligence, the Eagle 360 Urban learns from previous actions how to optimize future responses.

Made of super-elastic polymer, the tire’s bionic skin has a flexibility similar to that of human skin, allowing it to expand and contract. This outer layer covers a foam-like material that is strong enough to remain flexible despite the weight of a vehicle. Thanks to this flexibility, actuator elements beneath the tire’s surface, which are components that change shape with an electrical input, working like human muscles, can re-shape the individual sections of the tire’s tread design, adding ‘dimples’ for wet conditions or smoothing the tread for dry conditions. A new tread with a safer contact patch is thus deployed.

Using this morphing tread, the Eagle 360 Urban transforms and adapts to changing road and weather conditions. The concept tire can then interact to share the information it has captured, the related action and its success with other vehicles and all of the elements making up the Internet of Things.

When the tire’s bionic skin is damaged, the sensors in the tread can locate the puncture. The tire then rotates to create a different contact patch. This reduces pressure on the puncture and allows the self-healing process to start. The self-healing works thanks to materials which are specifically designed to be able to flow towards the puncture. They react physically and chemically with each other to form new molecular bonds, closing the puncture.

This new generation of tires will create added value for OEM partners and the evolving providers of Mobility as a Service (MaaS) by maximizing uptime and providing proactive maintenance. For the everyday commuter they will offer an improved experience by adding a new dimension to the safety performance and learning capabilities of autonomous driving.

We are on the verge of a revolution in mobility ….
129 million autonomous-capable vehicles are expected to be sold from 2020 to 2035.
The way we ‘drive’ or better, will be ‘driven’, will change significantly in the years and decades to come. And smart and sustainable technologies will increasingly define mobility.

Goodyear wants to reimagine the role of the tire. Tires are at the core of mobility today and tomorrow.
With the role of the driver evolving, the role of the tire becomes even more important.
Safety is a primary concern for the autonomous drivers and passengers of tomorrow.
As the only link between a driverless car and the road, tires can play a key role in addressing this.

Autonomous driving places new demands on the tires. According to a recent study from Navigant Research, 85 million autonomous-capable vehicles are expected to be sold annually around the world by 2035[1], for example. According to the J.D. Power 2015 U.S. Tech Choice Study, consumers are most concerned with ensuring safety.

We envision a future in which our products will become more connected with the vehicle and more versatile.
After 117 years of making tires, Goodyear presents a vision of a future tire that looks radically different from tires today —it’s a sphere.
This spherical 3-D printed concept tire presents an inspiring solution for the long-term future when autonomous driving is expected to be more mainstream. And tires can contribute to increased safety and comfort, advanced maneuverability and key data on road and weather conditions.

Spherical shape for ultimate maneuverability and safety
Imagine a tire that can move the vehicle in all directions, not only forward and backward but also sideward. This unique shape offers a wide range of benefits …
Imagine a daily commute in a fully autonomous vehicle…
You pull out of your parking spot sideways, at a 90° angle and start driving.
It is a cold and wet day, no worries, the car can seamlessly overtake sudden obstacles and reduce sliding or aquaplaning from potential hazards.

Sensors ensure connectivity with car and increase safety
The Eagle 360 concept is equipped with a number of smart sensors to read the road.

Active wear sensors will monitor tire condition by registering and optimizing the wear of the tire to extend mileage and further enhance safety.

Inspired by nature
Our engineers get inspired by great examples in the world of fauna and flora to enhance grip, handling, comfort, longevity, …
The tread of the Eagle 360 tread mimics the pattern of a brain coral its multiple blocks and grooves can secure a safe contact patch under all conditions.
The bottom of the tread features elements similar to a natural sponge to better regulate/manage water on the road, reducing the risk of aquaplaning.

Magnetic levitation
How do you fit a sphere to the car? Actually you don’t.
The tire is suspended from the car by magnetic levitation, same way like some trains already do.
This offers clear advantages like reduced noise and increased comfort.

The Eagle-360 will provide the safety, maneuverability and comfort to match the demands of autonomous cars and their users.
Goodyear’s concept tires play a dual role in the future both as creative platforms to push the boundaries of conventional thinking and testbeds for next-generation technologies.
It is our aim to move a generation forward towards a smart and safe future mobility.

IntelliGrip - advanced sensor technology for early generation autonomous vehicles

IntelliGrip

According to a study from the World Economic Forum, cities expect autonomous vehicles to become a reality in the next 10 years[1]. In addition, the J.D. Power 2015 U.S. Tech Choice Study[2] concludes that consumers deem collision protection technology most important in the wake of the changing automotive industry.

The Goodyear IntelliGrip concept tire, with its advanced sensor technology, is designed to support autonomous vehicle control systems. As autonomous vehicles rely on data from other vehicles, drivers, pedestrians and smart cities, tires such as the Goodyear IntelliGrip concept could play a critical role in the exchange of information.

Thanks to its advanced sensor technology and specially designed tread, the Goodyear IntelliGrip concept tire can sense many road conditions, including both surface and weather conditions. The IntelliGrip is also equipped with advanced active wear technology to assess the state of the tire and the vehicle and to optimize the autonomous control system of the vehicle.

In addition to sensing the road and tire conditions, the tire also communicates with the vehicle’s central computer system, which should contribute to delivering improved driving performance and safety. When the tire senses a rainy or slippery road surface, the autonomous vehicle will adapt its speed. Additionally, it should shorten the stopping distance, provide a better cornering response, optimize stability and even support collision prevention systems.

Goodyear is working with a number of car manufacturers to further adapt this technology to their needs, enhancing connectivity with features such as Electronic Stability Control Systems, Brake Control Systems and Suspension Control Systems.

First electricity generating concept tire

The BH03 futuristic concept tire has the potential to revolutionize the automotive industry

GY-Concept-BH03

As interest for electric cars grows in the global marketplace, this type of innovation is expected to play a role in ongoing discussions on the future of mobility. This visionary tire technology could eliminate the vehicle-range anxiety motorists may have with electric cars.

This concept has the capacity to produce its own electricity. Conceived by Goodyear’s Innovation Center engineers and simply called by its development code “BH03”, the tire can transform generated deformation into electrical energy.

This electrical energy could supply the batteries of the car’s hybrid powertrain, as well as other on-board technologies. The tire generates electricity via the action of two types of material:
• Thermoelectric material transforms the heat generated by a rolling tire into electric energy.
• Piezoelectric material transforms the pressure due to structure deformation into electric energy.

The tire is a purely conceptual development and is designed to be part of the company’s innovation thought process. There is no plan to release this tire to the market.

Goodyear TripleTube a smart morphing tire concept

Single tire actively inflates and deflates air chambers at different positions to provide versatility and optimized performance

Concept-Lexus-Triple-Tube

The TripleTube tire can inflate and deflate based on road conditions to deliver improved performance and versatility for drivers. The concept tire its technology could be linked to autonomous cars in the future by allowing the tire to “prepare” the shape it needs before it enters a curve. There is no plan to release this tire to the market.

It delivers ultimate performance in a single tire by automatically adjusting to three different positions based on road conditions:
• Eco/Safety Position: Offers reduced rolling resistance through optimized stiffness distribution. It also provides dry braking through a wide footprint in contact with the road.
• Sporty Position: Gives drivers dry handling through optimized contact patch using active conical shape.
• Wet Safety Position: Provides high aquaplaning resistance, through a raised tread in the center of the tire, leading to a bigger tire diameter resulting in a narrow and long footprint.

The tire relies on an internal pump that moves air from the main air chamber to the three individual air chambers. The multiple air chambers provide extended mobility, as one punctured chamber would still allow the driver to continue his journey.

The Triple Tube concept tire compound is also fully sustainable and made with silica derived from rice husk ash, a technology already announced by Goodyear in 2014.

The Triple Tube is a pure concept development and will not be produced by Goodyear. Concept tires are designed as part of the company’s innovation process and are developed to stir debate, discuss possible solutions and enable engineers to think out of the box to deliver smart solutions for a smart future.

Future SUV Concept Tire

goodyear-suv-concept-tire

In it's ongoing research into potential tire technologies, Goodyear has developed a concept, which builds on a standard SUV tire with a large central groove. Thanks to this groove the tire has a reduced contact patch with the road, which in turn could improve the tire’s overall rolling resistance, supporting ongoing efforts to enhance fuel efficiency and reduce CO2 released from the car. The reduction in this rolling resistance means that car engines do not need to work as hard to push the tire forward against the friction created by its contact with the ground.

The groove is also designed to evacuate large quantities of water and mud away from the tire’s contact patch during wet conditions, effectively offering a possibility to improve its overall wet grip.

Unlike many other concepts, the Goodyear tire does not put two small tires together on one rim, but builds the double contact patch tire on a single SUV tire construction. The approach means that the tire is able to support the load weight of an SUV, while still offering the benefits of a double contact patch tire. As an additional benefit, the removal of a large patch of rubber from the tire to create the groove means that the tire’s overall weight is reduced, delivering a more lightweight product which uses less rubber in production. The new concept is part of an ongoing effort at Goodyear to work around developing sustainable solutions for distant future.

Although the tire is not designed to be a marketable product, the concept SUV tire, is one of several possible ways to address rolling resistance and wet grip, both key criteria’s on the European tire label.

Spring Tire – next generation

The Goodyear ‘Spring Tire’ was co-developed by the U.S.National Aeronautics and Space Administration (NASA). It presents a future tire concept that could be used to explore the outer reaches of space, and possibly also the most rugged terrains here on earth.
