As Temperatures Drop, Check Tire Pressure More Often

Now that the weather is beginning to turn colder, you may notice the tire pressure monitoring system (TPMS) light on your dashboard has come on. It is recommended that you check your tire pressure regularly, especially during the winter, to help keep the TPMS light off and your vehicle safe.

It is normal during the colder months of the year for you to get TPMS warnings. Many times you see this warning light in the morning and then as the temperature rises throughout the day the light may turn off. It is still likely that the tires will still be a few PSI under inflated. For this reason it is important to check your tire pressure regularly.

According to the U.S. Tire Manufactures Association, for every 10 degree drop in air temperature, tire pressure decreases one to two pounds per square inch (PSI). An important part of vehicle safety, tire life and gas mileage, is maintaining correct tire pressure for your vehicle and tire specifications.

Incorrect tire pressure can lower gas mileage by 0.3 percent for every one PSI drop in pressure of all four tires and improve fuel efficiency by up to 3.3 percent when the correct tire pressure is maintained.

Your tire pressure should be checked at least monthly with a proper tire pressure gauge. It is important to note that newer cars with tire pressure monitoring systems may not alert you until the tire is significantly under inflated, so in the winter you may want to check more frequently. It is also important to check tire pressure whenever there is a significant weather change, which can occur more often in the winter months.
