Reasons behind Low Tire Pressure Light but Tires are fine
Be careful when the light on your TPMS system comes on. This means that one or more of your tires may be at least 25% below the recommended inflation pressure.
- Find a safe place to stop your vehicle away from traffic so you can stop to inspect your tires. NOTE: If you are driving at high speeds (highway), hold the steering wheel firmly with both hands because in the event of a flat tire (rapid deflation), you need to be prepared to control your vehicle. Then, slow down and get out of traffic.
- Once you have checked to make sure you do not have a flat tire, use a tire gauge to check the pressure in each of your tires to see if they are at the manufacturer’s recommended pressure level. (A tire gauge should be a standard component in your vehicle’s emergency supply kit.) ) The recommended pressure level is found on the tire placard, a label located just inside the driver’s side door.
- If you do not feel safe or secure checking the tire pressure on your own, proceed with caution so that a tire professional can check it*.
- Inflate your tires to the pressure indicated by the placard, either by using your nearest tire service center or by using a tire air supplier at your nearest inflation station.
- If necessary, have damaged tires serviced, or the TPMS system serviced at your nearest service station.
- The light on the TPMS system should go out within a few minutes of reinflating the tires to their recommended pressure.
*It is always best to check the tire pressure before driving with the tires, i.e. when your tires are “cold”, this ensures a more accurate reading.
Tire Pressure Affects Driving
Today, up to 40 percent of Americans drive on tires with air pressure below recommended levels, which affects directional stability, increases fuel consumption and damages tires.
If the lights on my TPMS system come on and I put air in my tires will the light go out by itself or do I have to take my car to the dealer or a tire shop?
When the TPMS system warning light comes on and flashes in the on position for one second and changes to off for three seconds this indicates a problem with the vehicle computer and can only be corrected by a dealer service center. When the TPMS system warning light comes on and stays on, it indicates a low-pressure condition in one or more tires. Inflating the tire to the recommended pressure on the door plate should result in the light going out. Remember that one or more tires may have low air pressure, so always check the pressure on all your tires.
