The tire pressure light can be quite alarming when it comes on. What does it mean when your tire pressure light comes on, and what should you do about it? This two-minute tire blog will answer questions like:
• What Is the TPMS Light? • Why Is My Low Tire Pressure Light On? • Is It Okay to Drive With Low Tire Pressure? • How Long Can I Drive With Low Tire Pressure?
Most modern vehicles have a tire pressure monitoring system (TPMS) that uses sensors located in each tire to measure the pressure and alert you if your air pressure falls below a certain level. This warning is typically indicated by an orange or yellow tire pressure light on your dashboard.
Many auto manufacturers allow up to 25% air loss before activating the TPMS light, which is usually around 30-35 PSI for passenger vehicles.
Your vehicle’s tire pressure light most likely indicates low tire pressure. However, there are a few instances in which that may not be the case.
• Low tire pressure: If one or more of your tires are underinflated, the TPMS light will come on to alert you. It’s important to make sure your tires are properly inflated to avoid any issues on the road.
• TPMS malfunction: If you see the tire pressure light come on and your tires prove to be properly inflated, it's a good idea to have your TPMS checked by a mechanic.
• Cold weather: The cold weather can cause your tire pressure to drop, which can trigger the TPMS light. In that case, it's a good idea to check your tire pressure and inflate your tires if needed.
• New tires: If you've recently had new tires installed on your vehicle, the TPMS light may come on as the system adjusts to the new tires. This is usually temporary. However, if the light doesn't go off, it's a good idea to have your TPMS checked by a mechanic.
If your TPMS has indicated low tire pressure, your vehicle is not considered safe to drive. We recommend pulling over and checking your tire pressure as soon as you’re able. And if you aren’t able to do so right away, then try to find a safe place to stop as soon as possible. Driving on underinflated tires can be dangerous, causing a variety of issues including poor handling, reduced fuel efficiency, and increased tire wear.
Since your low tire pressure light is an indication of an underinflation hazard, it is never recommended to drive with an unchecked low tire pressure warning. However, there are some emergencies in which you may need to get your vehicle to an air compressor or tire shop. In that case, you should only go a very short distance at a low rate of speed. This is because driving at low tire pressure for an extended time or at high speeds will most likely damage your tire and can be hazardous to you and your vehicle.
And if you find that you have a completely flat tire, stop driving immediately. In this case, either switch it out for your spare or call emergency roadside services.
