Goodyear Developing Self-Inflating Tires
The flat tire may become obsolete! Goodyear is developing a self-inflating tire. The technology will enable tires to remain inflated at the optimum pressure without the need for any external pumps or electronics. All components of the Air Maintenance Technology system, including the miniaturized pump, will be fully contained within the tire.
Goodyear says consumers have been wanting this type of tire for years. The closest tire companies have come are run-flats, which can be driven up to 100 miles after a puncture - as long as the side wall of the tire is not compromised.
Goodyear has not indicated how much the tires would cost or when they might be available at retailer stores. However, Goodyear points out that even slightly under-inflated tires can drop your mileage by 3.3 percent, costing you cash at the pump.
To further develop the tires, Goodyear has been awarded a $1.5-million research grant by the Department of Energy's Office of Vehicle Technology for a commercial truck application.
