Is the tire pressure monitoring on cars inaccurate?
2 Answers
Automotive tire pressure monitoring is accurate, with real-time monitoring of tire pressure values that can immediately detect air leaks. The automotive tire pressure monitoring system is divided into: 1. Indirect tire pressure monitoring system, which determines tire abnormalities through differences in tire rotation speed; 2. Direct tire pressure monitoring system, which involves installing four tire pressure monitoring sensors inside the tires to automatically and continuously monitor tire pressure and temperature whether the vehicle is stationary or in motion. The automotive tire pressure monitoring system can automatically monitor and alert for faults such as excessively low tire pressure, excessively high tire pressure, rapid air leaks, and excessively high tire temperature, ensuring adequate tire pressure to prevent tire blowouts, enhancing driving safety, reducing additional fuel consumption due to insufficient tire pressure, and extending the service life of the tires.
When I first bought my car, I was also worried about the accuracy of the tire pressure monitoring system. That winter, the alarm suddenly went off and scared me. When I took it to the repair shop, the mechanic said it was due to the aging sensor battery, which caused false alarms when the pressure dropped in cold weather. Now I know that these systems rely on sensors, and over time, battery degradation or loose installation can cause issues. It's recommended to check the sensor status every six months. If the alarm goes off frequently but no leaks are found, it might be a false alarm—don't rush to replace the tires. Instead, use a pressure gauge to manually confirm the tire pressure. Maintaining correct tire pressure is not only safer but also improves fuel efficiency. However, don’t fully trust the system; checking it yourself is the most reliable. Remember, climate has a big impact—high temperatures cause expansion, while low temperatures cause contraction, which can make the system either slow or overly sensitive. Just pay attention to your usual driving habits.
