Are Tire Pressure Monitoring and Air Gauge Normal?
1 Answers
Tire pressure monitoring and air gauges are normal phenomena. Any instrument will have errors, it's just a matter of accuracy. Generally, the accuracy of a tire pressure monitor is higher than that of an air pump pressure gauge. As long as the reading difference between the air pump pointer and the tire pressure monitor is not too extreme—since the visual error of the pointer reading is about 3-5 PSI, even if the accuracy is 2.5 grade—it is considered acceptable. Below is some relevant information about tire pressure monitoring: Function: The role of tire pressure monitoring is to automatically monitor the tire pressure in real-time during driving and alert the driver to tire leaks or low pressure to ensure driving safety. Classification: Tire pressure monitoring is mainly divided into two types: indirect tire pressure monitoring (Wheel-Speed Based TPMS, or WSB) and direct tire pressure monitoring (Pressure-Sensor Based TPMS, or PSB). There is also a composite TPMS. Tire Pressure Control: For normal driving, maintaining the tire pressure of all four tires between 2.2~2.5 bar is fine. If the vehicle is fully loaded and the trunk is carrying a lot of items, the rear tire pressure can be appropriately increased to 2.6 bar. Since the spare tire is not used for long periods, its pressure can be inflated to 2.8 bar.
