The temperature of the air around us effects more than just how many layers of clothes we need to put on that morning. It affects our vehicle’s tire pressure as well.
It’s that time of year again when temperatures will begin to fluctuate as we grow closer to summer. While you may be smiling about the delightful springtime weather, you need to be cautious of the pounds per square inch (PSI) in your tires to maintain your vehicle’s safety.
Did you know? Each 10-degree Fahrenheit drop in outside temperature can decrease your tire pressure as much as one to two PSI. Similarly, your pressure may increase approximately one to two PSI for each 10-degree Fahrenheit increase in outside temperature.
Monitor Local Weather Forecast
Checking your local weather on a regular basis will help you prepare for significant temperature changes.
Know Your Vehicle
Every vehicle is different. The vehicle make/model, as well as tire size, will determine the proper PSI. You can find your recommended PSI written on the tire, on the vehicle information in your door panel, or in your vehicle’s owner’s manual.
Check PSI Regularly
Tire Pressure Monitoring Systems (TPMS) were first installed in luxury vehicles in the late 90’s. Today, a TPMS is programmed into most standard vehicle models. TPMS lights on your dashboard are illuminated more frequently during the colder months, when you see the greatest drop in temperatures. However, transitioning through spring into the summer months may have a similar or greater affect on your PSI.
Whether or not you have a TPMS, automatic lights are not reliable. These are computer generated systems which can malfunction and/or be reset upon getting a new tire or repairing a flat.
It’s likely that if your TPMS light appears from a drop in overnight temperature, it may disappear throughout the day as the temperature rises. Still note that even after the notification no longer appears, the tire may still likely be under the recommended PSI.
Invest in a Pressure Gage
It’s wise to keep a tire pressure gage in your vehicle for regular pressure checks and maintenance. They are small and easy to use. Store it in your glove compartment or center console for easy access.
If your PSI is not at its recommended pressure, there are a few corrective options. Bring your vehicle to the DeKalb NAPA AutoCare Center that best fits your needs. Find your nearest location at http://napaautocaredekalb.com/locations/ or add air on your own at a local service station. Finally, you can purchase a compact air compressor to add air to your tires whenever needed at your convenience.
*Please note that the Barb City Automotive Care Center services wheel alignments/balance; however does not make repairs to the tire.
While too little PSI can lower gas mileage and impair the quality of your vehicle’s safety, too much PSI can limit the life of your tire. This is why maintaining the recommended PSI for your vehicle is important.
Following your recommended PSI will allow your tire to rest completely on the ground. If the PSI is too great, it will cause your tire to “donut” around the rim. This will cause you to drive only on the inner treads, causing the tire to wear down more quickly.
