AKRON (March 5)—Goodyear and Siemens A.G.'s Siemens VDO Automotive unit this week introduced their Tire IQ tire pressure monitoring system in Europe at the Geneva Motor show, at the Society of Automotive Engineers 2003 World Congress in Detroit and at the Tire Technology Exposition in Hamburg, Germany. Goodyear began work on the technology in the 1990s, but the current system works through a radio frequency tire tag developed by both Goodyear and Siemens. The tag—about the size of a watch battery and built into the tire—is made up of a computer chip and sensor that monitor tire temperature and air, and relay that information to the driver via a radio communications system developed by Siemens. Tire IQ also includes jointly developed software that calculates recommended tire pressure based on data including air temperature, tire pressure, tire load, vehicle speed and other driving habits. Goodyear is in discussions with several major vehicle manufacturers, and anticipates the technology could be available on new vehicles as early as the 2006 model year, said William M. Hopkins, Goodyear´s vice president, product and technology planning.
