WASHINGTON - You may be missing out on easy savings at the gas pump. And, it comes down to tire pressure.

Properly inflated tires can save you 12 cents a gallon at the pump, according to the U.S. Department of Energy.

Dan Zielinski, a tire safety expert, recommends getting your own tire gauge because the one at the gas station has probably been thrown around a few times. It may not be entirely accurate.

"Use the correct pressure. Don't look on the tire sidewall. Look for a vehicle label that's on the driver's side door or check the owner's manual ," he says.

He also says drivers should check their tire pressure every month and before long car trips.

And, check tire pressure when your tires are cold and before you drive.

"When you do drive, the tire warms up and the pressure expands," Zielinski says.
