Is a Car Tire Pressure of 2.2 Normal?
2 Answers
Not normal. According to the requirements of the international GBT2978-2008 standard, the standard tire pressure for regular tires is 2.4-2.5 bar. A pressure of 2.2 bar is below the minimum standard value, so it is not normal. Tire Pressure Reset Method: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal Tire Pressure: Usually, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire Pressure Monitoring Not Reset: After inflating the tires, if the tire pressure reset is not performed in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to turn on. Simply performing a tire pressure reset will resolve this issue. Damaged Tire Pressure Sensor: The tire pressure sensor, which is used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the tire pressure sensor is damaged while driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, the only solution is to replace it with a new component.
I've been driving for over a decade. Is a tire pressure of 2.2 still considered normal? I think it depends on what car you drive and how you drive it. Generally, tire pressure for family cars is usually between 2.3 and 2.5. For example, my own car recommends 2.4. In summer, driving on highways with low tire pressure can easily lead to higher fuel consumption and bumpy rides. Once, my tire pressure dropped to 2.2, and during a long trip, the tires heated up and deformed quickly, almost causing danger. Now, I make it a habit to check the tire pressure gauge every month, referring to the recommended value on the door frame label. If you're driving slowly in the city, 2.2 might not be a big issue, but maintaining it too low for a long time will cause the tires to wear out faster, which isn't worth it. I recommend buying a digital tire pressure gauge to check regularly and ensure it stays within the safe range.
