ENERGY-EFFICIENT TRUCK TIRE -- AID TO ENVIRONMENT

 ENERGY-EFFICIENT TRUCK TIRE -- AID TO ENVIRONMENT
 AKRON, Ohio, June 24 /PRNewswire/ -- It's growing more likely that the 18-wheelers rolling down America's highways actually are saving precious fuel and reducing environmentally damaging emissions, rather than the other way around.
 A new breed of energy-efficient truck tires is being offered by tire companies which claim that significant fuel savings can result when they are used in all the wheel positions of an 18-wheeler, according to Bryan L. Kinnamon, Goodyear's general manager of commercial truck tires.
 "Through advances in rubber chemistry and tire design, energy- efficient tires roll over the pavement surface more easily than conventional truck tires, so it uses less fuel to provide the energy needed to make the rig roll," Kinnamon said.
 Advances in Goodyear's EET truck tires are rooted in the company's long involvement in advanced polymer science. Polymer science was the source of rubber compounding innovations Goodyear used to meet the automobile industry's CAFE or Corporate Average Fuel Efficiency regulations.
 Early successes and subsequent refinement of the work led to introduction in mid-1991 of Goodyear's fuel-efficient Invicta GFE passenger tire for the replacement market, now being tested in Boston, Kansas City and Seattle.
 However, Goodyear fuel efficient truck tires, forerunners of today's EETs for commercial trucks, have been under development through major fleet testing for many years.
 Kinnamon said 1990 figures tracked by Petroleum Marketing Monthly showed 21.36 billion gallons of diesel fuel were used to propel the nation's fleet of more than a million transports.
 If an average 6 percent savings were actually achievable in real- world operating conditions, the cost of diesel fuel consumption could be reduced by more than $1 billion and would also have significant environmental implications, he added.
 However, the Goodyear executive cautions that before too much emphasis is placed on fuel savings derived from tires alone, independent truckers and fleet operators can examine numerous other elements under their control which are equally crucial.
 "The new energy efficient tires are an important addition to overall fuel economy," Kinnamon said, "but those gains result from complicated testing that takes into account controlled ambient temperatures, winds, rolling resistance and terrain."
 Kinnamon said that those concerned with fuel efficiency for their over-the-road operations must pay strict attention to the real-world factors that they can control...factors like the type of vehicle, driving habits, type of load, vehicle speed, weight and tire maintenance practices.
 "A truck traveling 55 mph instead of 65 mph will realize a 15 percent savings in fuel alone," Kinnamon said. "With all the other factors analyzed, it is possible to exercise a great deal of control over fuel costs.
 "Tire companies are concerned about the environment, and cutting fuel requirements results in a corresponding reduction of emission levels," Kinnamon said. "But independent truckers and fleet operators have a stake in this as well with their good conscientious practices."
