How and When to Check Your Tire Pressure

As you probably know, tires that are not inflated properly not only may wear excessively, lead to lower gas mileage, and can be a danger to you while driving. That is why it’s very important to know how and when to check your tire pressure. Here’s some tips on how to check your tire pressure, and more.

Your vehicles recommended tire pressure can usually be found on a sticker inside your drivers side door. It will also be listed in the owners manual – (and if not either of these, you can usually find them online). Tire pressure is measured in pounds per square inch. (PSI)

You will also probably see that the sidewall of the tires list a tire pressure as well – that is the MAX pressure the tire is allowed. You really should go with what is on the door or in the manual, as that is ideal.


You will need a tire pressure gauge – you should check the pressure when the tires are cold, so don’t do it immediately after driving since driving causes them to heat up and affects the pressure. Check them first thing in the morning, or after the car has cooled down. (it usually takes about 3 hours).

Once you have the gauge, you will need to remove the cap from the air valve, and be sure to put it somewhere you won’t lose it (I usually put it in my pants pocket).
Read the air pressure gauge – the pressure will appear on the screen of a digital one (which is what I recommend).
Compare the number on the gauge to the recommended tire pressure
Adjust air pressure if needed, then be sure to replace the air valve cap


So if your tire is lower than the recommended pressure, here’s what you need to do:
Be sure to park close enough to the air compressor so you can reach all 4 tires with the hose
Like when checking the tire pressure, remove the valve cap
Press the hose nozzle down on the valve stem – air should automatically flow – you should notice the tire inflating and feel the air through the hose
Remove the hose fitting or release the inflation lever – check the air pressure again (as described above)
Repeat the steps on each tire until they are inflated correctly
Replace the valve caps

Be sure to listen, if you hear or feel air coming from the hose nozzle, you need to make sure that is properly connected to the valve. Also listen for any possible leaks in your tires.


Over inflated tires are just as bad as under inflated – in fact, you could be more likely to skid on the road, or even hydroplane.

If the gauge is reading more than the recommended pressure, here is what you need to do to release air:

Press the small dot or bead on the back of the tire pressure gauge into the center of the valve stem on the tire – you should be able to hear the air release.
Use the gauge again to check the pressure.
Repeat the steps until you are at the proper tire pressure


Honestly tire air pressure should be checked at least monthly – and more when the weather changes. The pressure usually rises in the summer because of the heat, and drops when it gets cold outside. Just get into the habit of checking them regularly, even if they look fine, and make it a part of your regular routine.

If they seem to be cracking, breaking, or losing air more often, be sure to make an appointment with the service center, as one or all of them may need replaced.
