Goodyear Unleashes New Tire Technology

By Cornelius Nunev


Wheel-giant Goodyear will be displaying some new ideas in the world's oldest technology at the Geneva Motor Show this week. Along with a self-inflating model, the business intends to unveil an innovative tire filled with springs for use on extraterrestrial surfaces.

Tires for the future

Brand new tires are significant to Goodyear. It has a research and development team there solely to make sure the needs in the industry are being met.

Jean-Claude Kihn is the senior vice president and chief technical officer of Goodyear. He said:

"Goodyear has always been proactive in research and development, and we are looking forward to displaying a range of innovations that people will never have seen before. These technologies have been specifically developed to meet the ever-changing requirements of modern consumers and society focused on performance, sustainability, the environment and convenience."

Environmentally conscious

The global need for petroleum is one that Goodyear wants to get rid of. This is why it used "BioIsopren" in one of its tires displayed. Instead of using petroleum-based isoprene that most tires have, this tire uses bio-based material.

Also in the interest of reducing fossil fuel consumption, Goodyear will show off its Air Maintenance Technology, a self-inflating tire system that can help reduce fuel consumption by self-regulating tire pressure.

Kihn explained:

"Consumers often overlook the importance of maintaining proper tire pressure. We believe this technology will have immediate positive impact for drivers in terms of performance and for the environment through improved fuel efficiency, reduced emissions and extended tire life. Goodyear has taken on this challenge and the progress we have made is very encouraging to the point that we are now ready to demonstrate it in Geneva for the first time."

Could be sent into space

The brand new "spring tire," developed in collaboration with The National Aeronautics and Space Administration, is a concept designed for use on the moon or other extraterrestrial areas. It also could find some takers for use in the harshest areas on our home-planet.

The spring tire is supposed to be able to carry a ton of weight for long distances in tough areas. It has 800 springs in it, which is why it got its name. The types will do better than the wire-mesh tires that Goodyear intended for use on the Lunar Roving Automobile in the Apollo moon missions in 1971.

Joe Lettieri, Goodyear's lead researcher on the spring tire project, said:

"This tire is extremely durable and very energy efficient. The spring design contours to any surface providing maximum traction. All of the energy used to deform the tire is returned when the springs rebound, so it will not generate heat like a pneumatic tire."

Rubber changes based on weather

Goodyear and NASA chose to eschew rubber the lunar tires because of the material's susceptibility to extremes of heat and cold. Also, the unfiltered solar radiation on the lunar surface would degrade rubber.

Honor for R&D

The tire-maker was awarded the R&D 100 honor for its spring tires in 2010. This is the first time, however, the technology will be shown to the public with a practical application.

The Geneva Motor Show opened its doors to the public Thursday, March 8. Goodyear will display its new technology there until March 18.
