New technology keeps tyres at optimum pressure

Goodyear's Air Maintenance Technology (AMT) has been under development in laboratories over the past two years. Visitors to the Geneva International Motor Show will see how tyres can remain inflated at the optimum pressure without the need for any external pumps, electronics or driver intervention leading to a reduction in fuel consumption and CO2 emissions.

AMT will help ensure the optimum tyre pressure is maintained and as a result could mean substantial savings at the fuel pump with under-inflated tyres resulting in between 2.5 and 3.3% decrease in fuel consumption, according to government and industry research.

Drivers are not concerned about tyre pressure

Research conducted by Goodyear shows that consumers are unconcerned about their tyre pressure, with half of those surveyed not knowing when to check their tyre pressure and one in three motorists admitting they would not be very likely to check their tyre pressure even before embarking on a long trip. Properly inflated tyres are necessary to keep the vehicle's handling performance at optimal levels, especially its cornering abilities. Under-inflation means less evenly distributed pressure on the road. It also reduces the tread area that is in direct contact with the road.

"Consumers often overlook the importance of maintaining proper tyre pressure. We believe this technology will enhance safe driving and performance, and have a positive impact on the environment through improved fuel efficiency, reduced emissions and extended tyre life," explains Jean-Claude Kihn, Goodyear senior vice president and chief technical officer.
