Is it safe to drive with a tire pressure of 2.0?
2 Answers
It is not safe to drive. According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.0 bar is below the minimum standard value and is therefore 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, indicating the tire pressure reset is complete. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Usually, the system will alert if the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to remain on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new component.
To be honest, a tire pressure of 2.0 is a bit low. Normal tire pressure usually ranges between 2.2 and 2.5, and the exact value can be found on the sticker on the door frame. Last time when my tire pressure dropped to 2.0 and I drove on the highway, I clearly felt the steering wheel becoming heavier. Later, I found out from research that this could increase fuel consumption by 30% and easily cause cracks on the tire sidewalls. It's okay for short trips at low speeds to a repair shop, but definitely avoid long-distance or fully loaded driving. Last month, my neighbor had a tire blowout due to insufficient tire pressure, fortunately at a low speed. Now, I keep an electronic tire pressure gauge in the glove box and check it once a month when the car is cold.
