Monitoring and maintaining the air pressure in your vehicle’s tires is an essential part of vehicle safety and maintenance. The correct tire pressure makes your vehicle easier to handle and helps to extend the lifespan of your tires, as well as making your car more efficient, helping you save on fuel.

Why has my “check tire pressure” light come on?

You may find that the Tire-Pressure Monitoring System (TPMS) light in your dashboard has come on even though you recently checked your tire pressure. Don’t worry, this doesn’t mean that your tires are randomly leaking air, and a costly repair or replacement is most likely not in order.

In fact, the air pressure in our tires fluctuates naturally, and these fluctuations can become more severe in certain weather conditions. Gases reacts to temperature in an interesting way, expanding in the heat and contracting in cooler conditions. So, after summer as the nights start to get colder, you may notice drops in your tire pressure in the late evening and overnight. In very cold conditions, this drop can be large enough to make your car warn you about your tire pressure when you get in your vehicle in the morning, for example.

When should you check your tire pressure?

In general, you should check the air pressure in your tires once per month. However, if temperatures start to get colder and especially if they fluctuate a great deal from day and night, then you may want to have them checked more regularly. Because heat causes the air to expand and air pressure to rise as a result, you should always check your tire pressure when your tires are cold. This means that you shouldn’t stop at a garage after a 30-minute drive to check your tires.

It is best to either check your tire pressure at home before you drive off in the morning or to stop at an auto garage that is close to home, so that your car hasn’t driven too much before getting them tested. If you find that your tire pressure is too low, you can inflate them at any auto mechanic nearby. Chances are that your tire pressure has only dropped due to the temperature, but checking your tires regularly will also help you to spot if a leak is occurring.
