Inflate Your Tires

Buy a digital tire gauge in order to keep your car tires inflated to manufacturer’s recommended level of pressure; underinflated tires increase the resistance on the road, which uses more gas.

The rolling resistance of your car’s tires is increased if your tires are not fully inflated, and this causes you to use more gas. You can’t tell just by looking at a tire if it is underinflated, so it is a good idea to check tires every week or two with a digital gauge, which can be purchased at True Value on Centre Street for about $11. It is hard to say how much extra money you spend on gas if your tires are underinflated, but the Department of Energy estimates that Americans waste about 3.56 million gallons of gas a day due to driving on tires that are not properly inflated; this comes at a cost of about $14.2 million every day in wasted gas for US consumers.

ANOTHER REASON: Underinflated tires also increase their wear, so you could roll through a $400 set of tires a year.
