Checking Tire Pressure


There's more to checking your tire pressure than visually examining it to see if it looks a little low. Tire pressure is measured in PSI or pounds per square inch. The PSI on the side of your tires is the maximum pressure level and not the recommended level. Incorrect tire pressure can result in poor fuel economy, quicker wear on your tires, even flats.

Now let's talk about how you correctly measure your tire pressure. You will need a tire pressure gauge. These come in standard or digital.

1. Make sure that you check all four tires. Sometimes a tire will look fine when in fact the pressure is incorrect.
2. Find the recommended PSI for your car. This can be found in your owner's manual or inside the doorjamb on the driver's side. (Remember, don't go by the tire itself).
3. Make sure your tires are cool or you will not get an accurate reading.
4. Find the air valve on the tire. This is underneath the little cap that you use to add air to your tire.
5. Press the tire pressure gauge against the valve. Make sure that the seal between the gauge and the valve is solid and hold for a few seconds.
6. Look at the piece that was pushed out from the end of the metal tube. If you are using a circular dial gauge, look at the number where the needle indicates. The number that is closest to the metal base is your PSI reading.
9. Now you can add or release air to the PSI reading that you've just obtained.
10. Check the pressure again to be sure that it is correct and repeat the process on all four tires.
10. Don't forget to check your spare.
