What are the reasons for insufficient car tire pressure gauge?

[FranciscoLynn]

Car tire pressure may be insufficient due to the following reasons: 1. The tire pressure has not been recalibrated. Simply recalibrate the tire pressure on the central control system. 2. If the tire pressure warning appears some time after inflating, but there is no puncture in the tire, it may be due to air leakage caused by wheel rim deformation. It is recommended to check the wheel rim and replace it if necessary. Regarding the relationship between tire pressure and car performance: 1. The relationship between tire pressure and load capacity: Tire pressure is an indicator of a car's load capacity. The load capacity of a car depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity. 2. The relationship between tire pressure and car power performance: Tire pressure greatly affects the rolling resistance coefficient. When the pressure decreases, the rolling resistance coefficient increases rapidly because lower tire pressure causes greater deformation of the rolling tire, increasing hysteresis loss.
