New technology from Goodyear could make manually pumping air into your tires a thing of the past.

Goodyear's Air Maintenance Technology (AMT) will keep tires inflated at optimum pressure without the need of external pumps.

Goodyear spokesperson Keith Price says all components of the system, including a miniature pump, will be inside the tire, powered by the motion of the car.

"The sensor would note that the tire was low and as you drove along it would put enough air back in your tire," Price said.

Price says AMT will not be able to fix punctures in the rubber from nails or glass, but it will save you the trouble of manually checking and adding air to normal, under-inflated tires.

"This would eliminate the slow leaking of air out of your tires because of variations of [outside air] temperautre and air seeping through the rubber," Price said.

Keeping tires properly inflated could save you up to 12 cents per gallon at the pump.

Price says Goodyear doesn't know when the technology will be available, but it could be here sooner than you think.

"The Department of Energy in Washington awarded us a $1.5 million grant for the research, development, and demonstration of the system for commercial truck tires," Price said.
