55% of Vehicles Have One Under-inflated Tire
June 16, 2010, WASHINGTON – A recent nationwide survey by the Rubber
(RMA) shows 55 percent of vehicles have at least one under-inflated
tire and only one in six vehicles has
four properly inflated tires.
Other findings revealed:
15 percent of vehicles have at least one
tire under-inflated by 8 psi.
20 percent of vehicles have at least one
tire under-inflated by 6 psi.
31 percent of vehicles have at least one
tire under-inflated by 4 psi.
However, compared to a similar survey
last year, “motorists showed some
improvement in tire care
habits,” according to RMA officials.
“This year, almost twice as many
vehicles had four properly inflated
tires as had last year.”
The survey’s best performing cities,
those with a higher percentage of
vehicles with four properly inflated
tires, were Honolulu, Baltimore, Boston,
Providence and Charlotte. At the bottom
of the list were Dallas/
Ft.Worth, Los Angeles, Orlando, San
Antonio, and Birmingham, according to
Properly inflated tires can improve fuel
efficiency by 3.3 percent and save nine
cents per gallon at the
pump, according to the U.S. Department
of Energy. Approximately 1.2 billion
gallons of fuel are wasted
each year by U.S. motorists driving on
under inflated tires.
The National Highway Traffic Safety
Administration (NHTSA) estimates that
contribute to more than 600 fatalities
and 33,000 injuries each year.
