'U.S. Drivers Paying More Attention To Tire Pressure'
About half of American drivers claim they check their tire pressure monthly, up from about 15% two years ago, according to a poll by Uniroyal Tire.
The company points out that underinflated tires wear out faster, impair vehicle handling and, according to the National Highway Traffic Safety Administration, reduce fuel economy by 1% for every 3.3 psi of underinflation.
The survey finds 50% of motorists (twice as many of them men as women) wrongly believe that a tire's correct air pressure is indicated on its sidewall. Actually, Uniroyal notes, that figure indicates the tire's maximum allowable pressure and is typically about twice what OEMs recommend. Correct tire pressures are listed in the owner's manual and on a label usually located on the driver's door jam.
