Tire Pressure Monitoring System (TPMS) alerts driver to low tire pressure in a specific tire.

It is that time of year again when this wonderful little light likes to shine or even blinkĀ  reminding us that the weather is changing and it is cold! Like the light pictured above, this “service announcement” as I like to call it is telling us that we need to check our tire pressure. Air pressure in a tire can go down about 1-2 pounds (PSI) for every 10 degrees of temperature change. Gas expands with heat and contracts with cold . So when winter arrives, it’s best to check on your tire pressure for safety precautions.
One of the most important, yet usually forgotten about maintenance feature that we need to pay attention to is making sure that the proper amount of air pressure is in each tire. Under-inflation can cause several problems including wear on the tires, poor gas mileage, affect steering and handling, braking in time, and can generate heat which causes blow outs. This can all be prevented by paying attention to that little light or even going ‘old school’ and using a manual tire pressure gauge to check the PSI level in each tire. It never hurts to check your tire pressure with a tire gauge atleast once a month. Even to a tire specialist an under-inflated tire can look fine.
For reference, there is information right inside your car that will help achieve the proper amount of tire pressure recommended by your vehicles manufacturer. This can be found in the glove box door, the owners manual, and/or the driver’s side doorjamb.

 

HOW TO CHECK YOUR TIRE PRESSURE WITH A MANUAL GAUGE:
1) Remove the black cap from the tire valve and make sure that the gauge’s measurement stick is completely inside the tire gauge.
2) Place the open end of the gauge over the tire valve stem firmly. Once the measurement stick pops out, read the number on the far right of the stick. This number is your tire pressure in PSI (pounds per square inch).
3) Repeat this a few times on each tire including your spare to ensure an accurate reading.
