Tires auto-inflate with new Goodyear technology
Goodyear’s new Air Maintenance Technology (AMT) enables 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.
“While similar in concept, there are significant differences in AMT systems for consumer and commercial tires,” said Kihn.
Goodyear says 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 passenger vehicle or commercial truck, underinflated tires result in between a 2.5% and 3.3% decrease in fuel mileage, according to government and industry research.
