Goodyear's AMT tyres are inflated to optimal pressure through a miniaturized pump contained within the tyre. As the vehicle drives forward, the pump automatically pumps the tyre to the best pressure. It focuses on that 'just right' balance, not over or under pumping the tyre.
"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.
According to government and industry research, a tyre that is not fully inflated can cost drivers up to 3.3 % extra at the fuel pump. Tyres that are not running optimal tyre pressure need more petrol to propel cars forward, causing drivers to travel less distance on the same tank of fuel.
There's more safety perks too, with more traction comes better deceleration, longer tyre life, lower emissions, improved vehicle performance and enhanced safety.
Goodyear hasn't communicated when the tyres will hit retailers, but they do believed production will be accelerated thanks to US and European government grants.
