Save Gas and Money With Your Tires

The wrong pressure in your tires could be costing you as much as $800 a year in wasted gas. For great drives and fuel efficiency, adjust your tires properly.

There are some 250 million vehicles on the road in the United States. How much money and gas do you think we could save if everybody's tires were inflated properly?

$23 billion and 3.3 million tons of carbon dioxide emissions could be saved -- not to mention millions of gallons of high-priced gas -- if all our tires were properly inflated.

So forgive the really bad pun -- but -- the only good inflation is proper tire inflation.

Tire pressure changes one pound for every 10 degree change in outside temperature, so warmer spring temperatures mean it is an ideal time to check tire pressure.

Always check pressure when the tires are cold, since driving even a couple of miles to the gas station can provide a false reading.
  • Under-inflation generally provides a smoother ride, but it also causes tires to wear out at the sides, and it wastes gas because tires need more power to push the vehicle.

  • Higher pressure generally results in improved steering response and fuel economy, but a stiffer ride, and it wears out the tread in the center.

Even the experts get it wrong. Top automotive website tested vehicles driven by 212 of their employees and found a bunch substiantially under-inflated and wasting gas. (full disclosure here -- I write for them occasionally) discovered they would save nearly 6,000 gallons of gas a year and about $20,000 of their boss' money, by keeping tires properly inflated.

So go check your tires. It could make your great drive more fuel efficient.
