We all have heard that you can get better gas mileage by keeping the tires on your ride at the recommended air pressure.
But, if you are like me, tire pressure checking just doesn’t get done very often during winter weather. Now that spring is providing us with some nicer days, it is time to keep the pressure up.
Try remembering to check your tires every time the price of gas jumps up. Well, maybe not that often. How about once a month on the day the mortgage or rent payment is due.
The problem is compressed air tries to leak out all the time. Most tires hold their air in pretty well, but many do leak some. Over time, the pressure will get lower than it should be.
Driving on tire that has low pressure is like driving up and out of a pothole continuously. That uses more gas than needed and wears out your tires quickly. Both waste your money.
Low tire pressure makes your car or truck more expensive to drive. You need to fix air leaks in your tires to save money at the gas pump.
You say OK, but what should the pressure be?
That is easy just talk to you car, or actually read your car.
Here I’ll show you how. See this is a photo of the driver’s door on my car.
This is a photo of the outer edge of the door. Notice: the sticker on the edge of the door.
Here is a close up of the sticker on the driver’s door.
It says recommended cold tire pressure 30psi. That means that the folks who built the car recommend that the pressure in the tires should be 30 psi.
There is a note that the pressure may be 4 psi higher when the tire is hot. Tires do get hot due the flexing as the weight changes onto a different part of the tire are the car rolls along.
Next time you open your drivers door take a look.
You could look it up in your owners manual but by the time you find the book and the right page you could have read the door sticker been done with it.
I have a tire pressure gauge in the glove box of both our cars so I can always find one. I’ll admit that I usually eye ball check the tires and use the gauge only when one looks low. The problem is that by the time I can see it the pressure has been too low too long.
My wife’s car is newer and sounds an alarm when the tire pressure is low. But again, by the time the alarm is triggered it has been too low too long.
Save money by using the gauge once a month or more often. If you are taking a driving vacation, check the tires before you start out, so you will get the best mileage for the whole trip.
