How long does it take to calibrate the tire pressure monitoring system on a Volvo S90?

[LeLillian]

The calibration of the tire pressure monitoring system on a Volvo S90 does not have a fixed time. It cannot be calibrated while stationary; the vehicle must be driven for calibration to occur, typically requiring driving about one intersection. It is recommended to check tire pressure once a month, and you can have the car wash shop inspect it during a wash. Most passenger cars are recommended to maintain a tire pressure of 2.3-2.5 bar, while mid-size SUVs may consider 2.5-2.7 bar. Tire pressure can fluctuate by 0.1-0.3 bar in different seasons. Relevant information about tire pressure is as follows: 1. Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power. 2. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort.
