The Importance of Tire Inflation in Gas Prices

Tires' importance at the gas pump is growing as gas prices climb, with U.S. drivers' currently paying among the highest fuel prices on record, and tire inflation is playing a big role in the price.
Tires' importance at the gas pump is growing as gas prices climb, with U.S. drivers' currently paying among the highest fuel prices on record, and tire inflation is playing a big role in the price.
When tire care is factored in, the rising fuel prices become even scarier. An underinflated tire deflects more energy and increases rolling resistance, which robs the vehicle of fuel efficiency. 'Running a tire 20 percent underinflated, only 5 to 7 pounds per square inch, can increase fuel consumption by 10 percent'.

The Energy Department has reported that every pound per square inch of tire underinflation wastes 4 million gallons of gas daily in the U.S. This can easily cost motorists two or three miles per gallon. Not only that, but the tire's tread life is reduced by 15 percent,' reports John Peer, director of retail operations for The Goodyear Tire & Rubber Company.

The Society of Automotive Engineers reports that 87 percent of all flat tires have a history of underinflation. In the 1970s, the National Highway Traffic Safety Administration claimed that half the nation's cars had underinflated tires. Other studies stated that 25 to 28-percent had at least one tire 'seriously underinflated' [4 psi or more below the manufacturer's recommendation.

According to 2002 research by the Rubber Manufacturers Association, nearly 90 percent of drivers surveyed do not check their tire pressure properly and many do not know enough about how to care for their tires correctly. The survey also found that 66 percent of 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 monthly or before a long trip. Tires should be inflated to the vehicle manufacturer's recommendations printed on the vehicle door placard or in the owner's manual, not the maximum limit stamped on a tire sidewall.

On www.goodyeartires.com, visitors can find extensive information on tire care, product selection and more. A section called "Know Your Tires" details how a tire is made and provides tire maintenance tips.

Through a link, website visitors can request a copy of "The Complete Tire Safety Guide." At Goodyear-owned tire and service outlets, Peer said consumers can have their tires checked for free, including an inspection of tread condition and tire inflation.

The U.S. military invaded Liberia in 1926. With the rubber tree as an abundant natural resource, Firestone set up shop.

Kroeker -- former police chief of L.A. (Rodney King era) and Portland (when Iraq war protestors were assaulted) -- now works in Liberia as head of security.

Little has been in the news about Liberia lately. Our corporate media doesn't report much about Africa. Do you know what is up there?

It worked for me

Size and traction of tire also can affect gas mileage. I just increased my fuel mileage significantly with a set of new tires. You should upgrade your tires if at all possible, the savings were noticable after the first fill-up.

No matter how old your tires are, checking ones tires for the correct air pressure at regular intervals, is a good thing; for longevity of the tires and for gas mileage. Especially in extreme weather conditions (like the heat we are getting the next few days), when it is hot outside your tires will expand and if you don't have the right air pressure to compensate, you won't be getting very good gas mileage and might even have a flat tire once the tire cools down.

Remember to check your tire pressure while the tire is cool - best time is before you make your first drive of the day.
If you check the pressure after driving for awhile or, if you check the pressure as your tires sit in the sun, especially in the summer, you will not get a accurate reading,(the reading will be higher than it actually is due to the aforementioned heat expansion of the rubber tire)

Of course you need to buy a tire gauge to do all the checking, don't rely on gas station air hoses, they are hardly ever accurate, auto parts stores have gauges for a few bucks.

My bike tires inflate to 120 psi. Talk about low rolling resistance. The best way to save on gas is to get a bike. Car tires only inflate to 40 psi.
