Goodyear is working on an entirely new innovation that could do away with having to ever manually add air to under-inflated tires. The new tires use a what is being called Air Maintenance Technology (AMT), with a miniaturized pump fully contained within the tire that keeps it inflated at the optimum pressure. This also means that, at all times, your tires will have the optimal amount of air ensuring that your vehicle is getting its most efficient mpg.
Goodyear hasn’t confirmed when the technology will be available, but its development has been accelerated thanks to recent government research grants in both the United States and the European Union. Hopefully those development grants will help offset the cost of bringing the tire to market, which is likely to be passes on to consumers.
