Save gas by checking your tire pressures, says Goodyear
Akron, Ohio – Representatives of The Goodyear Tire & Rubber Company say a close watch on the air pressure in a vehicle’s tires is an effective way to keep fuel consumption in check.
Motorists can improve gas mileage by around 3.3 percent simply by keeping tires inflated to the proper pressure, according to the U.S. Department of Energy, which says underinflated tires can lower gas mileage by 0.4 percent for every 1 PSI (pound per square inch) drop in the pressure of all four tires. Plus, properly inflated tires are safer and last longer, according to the Department of Energy’s http://www.fueleconomy.gov/ web site.
Goodyear says running a tire 20 percent underinflated — only 5 to 7 PSI — can increase fuel consumption by 10 percent. That easily may cost motorists two or three miles per gallon.
Proper tire care begins with knowing where to look, and then making it part of a regular vehicle maintenance program.However, according to February 2005 research by the Rubber Manufacturers Association, 85 percent of drivers surveyed do not check their tire pressure properly, and many simply do not know enough about how to care for their tires correctly. Most drivers don’t even know where to find the recommended proper tire inflation pressure for their vehicles’ tires.
Goodyear recommends that motorists should check tire inflation at least monthly or before a long trip. Tires should be inflated to the vehicle manufacturer’s recommendations printed on the vehicle doorjamb, in the glove box or in the owner’s manual, not the maximum limit stamped on a tire sidewall.
