Goodyear Presented A Concept Tire For SUVs At Geneva
|   Tuesday, March 18, 2014
Goodyear exhibited at the International Motor Show in Geneva a new SUV tire concept car designed in support of efforts to improve fuel efficiency. 

The concept, which has not yet been named, is based on a standard tire for SUV and presents a wide central groove. 

Thanks to the grooves, the tire has a reduced contact patch with the road surface, which instead give an improved level of rolling resistance of the tire, which supports efforts to improve fuel efficiency and reduce emissions CO2 car.




Reducing rolling resistance means that the car's engine does not have to work hard to push the tires against the friction resulting from their contact with the ground.
The groove is also designed to drain and remove large amounts of water and mud from the tire contact patch in wet conditions, offering a real opportunity to improve the overall performance of the tire's wet grip.

Unlike many other concepts, Goodyear tires do not put two smaller tires on the same rim, but effective builds a double contact patch in a single envelope, a single case of a tire designed for SUVs. 

This means that the tire can support the weight of an SUV, while continuing to provide the benefits of a double tire contact patch. As an added benefit, the removal of large pieces of tire rubber to create this groove is also equivalent to the fact that the total weight of the tire is reduced, thereby delivering a product with a lighter weight using less rubber in the production process. 

The new tire concept is part of a constant effort to develop sustainable Goodyear solutions for the far future.

Although the tire was not designed to be a market product, the new concept tires, which are also mounted on the new concept car from Hyundai Intrado, are one of many ways to tackle rolling resistance and wet grip, both key criteria under the new EU tire label.

Among other features present in this tire, we find the Auto-Clean Hydrophobic textures type designed to expel mud and other solids from the tire tread pattern and special fabrics designed and incorporated into the tire for a high level of external noise reduction that the tire makes when rolling on asphalt.

This tire concept offers a preview of a potential solution on mobility within a tire with two air chambers, one on each side, both interconnected by a valve system that allows the tire to run even after being stung in one of the two air chambers.

The tire is only in the concept stage and is part of ongoing research efforts undertaken by Goodyear.

"At Goodyear we are always working to identify key opportunities for future development possibilities", said Jean-Pierre Jeusette, Director General of Goodyear's Innovation Center in Luxembourg. "We spend hundreds of hours discussing, analyzing, learning, designing and developing new ideas and concepts across our research and development facilities in both Europe and the United States. The result of this thinking is often molded into tire concepts which are then used to stimulate further developments.

This tire is no different, and it provides the world with an example of our development process at Goodyear. It is by far not the only concept we are looking at for similar applications, reflecting the complexity of the tire engineering process we go through to deliver new and innovative products to the market, today and in the future".
