Is It Safe to Drive With a Faulty Tire Pressure Sensor?

Tire pressure sensors are an important safety feature in modern vehicles, designed to alert drivers when one or more tires are significantly underinflated or overinflated. While it may be tempting to ignore the warning light and continue driving, doing so can be extremely dangerous and lead to serious consequences.

Dangers of Driving With a Faulty Tire Pressure Sensor

When a tire pressure sensor is faulty or the TPMS (Tire Pressure Monitoring System) warning light is illuminated, it means that the system is unable to accurately monitor the air pressure in one or more tires. This can have several dangerous implications:

Uneven tire wear: Underinflated tires will wear more quickly on the outer edges, while overinflated tires will wear in the center. This uneven wear can lead to poor handling, reduced traction, and increased risk of a blowout.
Increased risk of a blowout: Driving on underinflated or overinflated tires puts additional stress on the tire, making it more susceptible to a sudden and catastrophic failure, known as a blowout. A blowout can cause the driver to lose control of the vehicle, potentially leading to a serious accident.
Reduced fuel efficiency: Underinflated tires create more rolling resistance, which means the engine has to work harder to move the vehicle. This results in decreased fuel efficiency and higher fuel costs.
Damage to the tire and wheel: Driving on a severely underinflated tire can cause the tire to separate from the wheel or the wheel to become damaged, leading to costly repairs and potentially stranding the driver.

Proper Tire Maintenance

To ensure the safety and longevity of your tires, it’s important to regularly check and maintain proper tire pressure. Here are some tips:

Check tire pressure monthly: Use a reliable tire pressure gauge to check the pressure in all four tires, including the spare, when the tires are cold (i.e., the vehicle has been parked for at least three hours or driven less than one mile).
Inflate tires to the recommended pressure: The recommended tire pressure can be found in the owner’s manual or on a sticker located in the driver’s side door jamb. Never exceed the maximum pressure listed on the tire sidewall.
Replace faulty tire pressure sensors: If a tire pressure sensor is faulty or the TPMS warning light remains illuminated after checking and adjusting the tire pressure, have the sensor replaced by a qualified mechanic as soon as possible.

Conclusion

Driving with a faulty tire pressure sensor or an illuminated TPMS warning light is never a good idea. It puts you and other drivers at risk of a serious accident and can lead to costly damage to your vehicle. By regularly checking and maintaining proper tire pressure and promptly addressing any issues with the tire pressure sensors, you can ensure a safer and more enjoyable driving experience.
