My fiance is the one who corrected my idiotic way of checking tires. I would just look at them and if none of them looked "low", I'd shrug and move on.
So, many of you probably already know this info, but since it escaped me for so many years, I will assume nothing.
Checking your tire pressure can get you better gas mileage and save you some $$$.
I know for us, our MPG jumped around 15% when our tires are inflated correctly. Not only that, but making sure your tires are properly inflated will allow them to last longer.
Under-inflated and over-inflated tires can cause them to wear out prematurely.
First off, your tires need to be cool when checking the pressure. Your tires will appear to be more inflated when warm aka having been driven. I would suggest checking them in the morning before you use your vehicle.
Find out what the proper tire pressure is for your car. You will find a sticker on the driver side door jam that has the info.


Our vehicle is 32 psi.
Take a tire gauge and press it into the valve. If you hear the air hissing then you haven't attached the gauge properly. Once properly on the valve, take the reading.
Let's say the reading is 29 psi. You have to add air until the gauge reads 32.
Do this for all 4 tires and check about once a month or when you notices your mpg dropping.
NOTE: The psi reading on your actual tire is the MAXIMUM pressure your tire can take. Unless your are hauling a heavy load somewhere, avoid the max psi
Also, don't forget to check your spare tire. The psi reading for it is on the same sticker inside the door.
I know this may be a "duh" blog post, but like I said, I never used to check properly and then I filled my tires according to the psi on the tire.
It's a simple fix that can save you some $$$ and help your car run more efficiently.
