What is the normal tire pressure for small cars?

[McHadley]

Small cars generally use standard tires with a tire pressure range of 2.4-2.5 bar. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. There are generally three reasons for abnormal tire pressure: Tire pressure abnormality: Usually, an alarm will be triggered if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to illuminate. For sensor damage issues, the only solution is to replace it with a new component.
