You may or may not know that one of the best ways to save at the pump is to make sure your tire psi is exactly where it should be. With gas prices as they are, even a small percentage of difference in your miles per gallon (MPG) can lead to a difference you can see the next time you fuel up.
In fact, when you keep your tires properly inflated, you can get up to 3.3 percent better gas mileage. Think about what that would do with today’s gas prices. If you were to receive 3.3 percent back every time you filled up at a gas station, how much would you save every trip? What about every month? Now tally that up to your savings for the year. It doesn’t take long to see why using a good quality tire pressure gauge is one of the best ways to save a lot of money.
In terms of gasoline savings, consider it about $0.07 per gallon at the current average gas prices. For every gallon, you’ll get 7 cents back. That’s a figure that adds up very quickly and should be considered free money. Especially when all you need is a digital tire pressure gauge and some air to benefit from that savings.
Remember that you can’t necessarily tell if the air pressure tires hold is ideal unless you measure it with a gauge. It’s not something you can tell just by looking at it from the outside. Also, there are many different factors – including the temperature of the air outside – that can impact the inflation of a tire. The impact is so great that for every 1 psi reduction in all four tires, you lose 0.3 percent in MPG.
In order to make sure that you’re using the right tire air pressure, first find out what the ideal actually is. This is usually located on a sticker on the inside of the driver’s side door jamb. It may also be in the owner’s manual for the car. Don’t use the maximum pressure on the sidewall of the tire as your guide as that is not the idea, it’s the maximum.
Next, use a good digital tire gauge to measure the pressure. Measure it before you drive your car, as tires that have been recently driven will read higher than ones that have been idle for a while. You may be tempted to simply use the gauge at the gas station, or one of those promotional freebies that you’ve been handed at some point. Those may not be as accurate as you think. Since every 1 psi makes a difference, it’s worth your while to choose a gauge that will give you a very accurate reading. Do this at least once per month, but twice per month is even better, particularly at times in which the weather is changing.
Once you have your reading, you can adjust the tire air pressure if needed and feel good in knowing that you’re saving money each time you fill up the gas tank.
