'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.
