 Goodyear announces self-inflating tires
Goodyear tire - 8.12.2011

The tire of the future

It sounds like something out of a Bond film, but Goodyear has developed a new system which allows tires to automatically inflate themselves.

Called Air Maintenance Technology (AMT), the system features a miniaturized air pump that is fully contained within the tire. Goodyear provided no indication when the technology will start appearing in consumer products, but the company said AMT is powered by the tire's rotational energy.

According to Chief Technical Officer Jean-Claude Kihn, "A tire that can maintain its own inflation is something drivers have wanted for many years. This will become the kind of technological breakthrough that people will wonder how they ever lived without."

New Goodyear Innovation Could Make Tire Pumps Obsolete

Government Grants to Help Quicken Development

AKRON, Ohio, Aug. 11, 2011 /PRNewswire/ -- The days of manually adding air to under-inflated tires could be a distant memory thanks to a new innovation under development in laboratories at The Goodyear Tire & Rubber Company (NYSE: GT).

Keeping tires properly inflated doesn't just eliminate the practice of checking a tire's air pressure and finding a tire pump and gauge that works. It also can mean real savings at the fuel pump.

Whether you drive a passenger vehicle or a commercial truck, underinflated tires result in between a 2.5 percent and 3.3 percent decrease in fuel mileage, according to government and industry research. At today's prices, that translates to about 12 cents per gallon at the pump.

Properly inflated tires also result in lower emissions, longer tire life, enhanced safety and improved vehicle performance.

Goodyear's Air Maintenance Technology (AMT) will enable tires to remain inflated at the optimum pressure without the need for any external pumps or electronics. All components of the AMT system, including the miniaturized pump, will be fully contained within the tire.

"While the technology is complex, the idea behind the AMT system is relatively simple and powered by the tire itself as it rolls down the road," said Jean-Claude Kihn, Goodyear senior vice president and chief technical officer.

"A tire that can maintain its own inflation is something drivers have wanted for many years. Goodyear has taken on this challenge and the progress we have made is very encouraging," said Kihn. "This will become the kind of technological breakthrough that people will wonder how they ever lived without."

Goodyear did not provide an estimate as to when this technology would be available at tire retailers, but said the timetable would be accelerated due to recent government research grants in United States and European Union.

The United States Department of Energy's Office of Vehicle Technology Wednesday announced it has awarded a $1.5 million grant for research, development and demonstration of the AMT system for commercial truck tires. The grant will be administered by the National Energy Technology Laboratory and work will be conducted at Goodyear's Innovation Center in Akron, Ohio.

In July, Goodyear successfully applied for a grant from the Luxemburg government for research and development of an AMT system for consumer tires. That work will be conducted at Goodyear's Innovation Center in Colmar-Berg, Luxembourg.

"While similar in concept, there are significant differences in AMT systems for consumer and commercial tires," said Kihn. "The tangible support from both the U.S. and Luxembourg governments underscores the value of these projects and the many positive benefits they can provide drivers around the world."

In addition, The DOE's Office of Vehicle Technology today also announced that it will award a $1.5 million grant for a joint project between PPG Industries and Goodyear to improve the rolling resistance and fuel efficiency of tires. The project's objective is to increase average fuel efficiency of passenger vehicle fleets through use of new tread and inner liner technologies.

"Advanced technologies that are invisible to the human eye - like those we are working on with PPG - will help to dramatically improve fuel efficiency of tires while maintaining other important qualities such as traction and tread-life," said Kihn.

Goodyear is one of the world's largest tire companies. It employs approximately 73,000 people and manufactures its products in 54 facilities in 22 countries around the world. Its two Innovation Centers in Akron, Ohio and Colmar-Berg, Luxembourg strive to develop state-of-the-art products and services that set the technology and performance standard for the industry.

Sounds cool, but it also sounds like just one more thing to break. I wonder how much weight they would add and what they're going to cost for a set.

Read "miniaturized air pump", therefore extreme low weight - possibly insignificant in the overall scheme. As to cost? I would suspect very low as well, besides, what you save in gas will likely cancels this out very quickly.

Just look at the Run on Flat much worst much heavier much expensive

what about cars that are stored and not driven. the tires deflate so the tires do not inflate them self, you should say tire inflate themselves while you are driving.

its probably too slow for that, you would damage the rim if u did that. U probably need to fill it up till its not riding on the rim b4 u started driving and let it fill up to full pressure

oh i see. you don't have to go to the gas station to check your tire pressure because it will adjust by itself when your tires are low in pressure. cool idea! I thought it was something that will inflate by itself when you get a puncture. does it?

How are the tyres going to know what presure should they have? You can put the tyre on a bunch of different cars with different pressure needs? What about when the car is loaded with people how are you gonna do to get the air pressure correct?

there is a pressure sensor attached to the rim. The tire is covering it so you dont see it. most of the new cars have them now. this system just inflates the tire when the sensor senses the tire pressure is low.

Cars are becoming more expensive because of laziness. I check my tire pressure routinely even though I have run flats which have saved my life at highway speed and less chance of a blow out. We need electronic stability control so when we are driving our cars at 70 miles per hour with our coffee in one hand and the cell phone in the other if we are not paying attention to driving the electronic nannies should kick in at the last minute. Just like our Congress acting on things in the last minute when it is an emergency .

Airbag and anti-lock brake got similar reactions in their inceptions, folks.

Fantastic...! I'll buy the first self-washing car! :)

I dont think this will work in high performance cars as it would definitely present a challenge in keeping the wheel balanced at high speeds. The air pump motor would have to weigh the same as a wheel weight (a few grams). Is that even possible?

Try not to think of a pump as you know it... Have you ever had your blood pressure taken? Think od the tube they wrap around your arm and the bulb they press... Now what if the sidewall of the tyre were the bulb? Would it not use the energy otherwise lost through heat as it flexes at the bottom to rather pump air?
