What is the appropriate tire pressure for a spare tire?
1 Answers
According to the regulations and requirements of the international GBT2978-2008 standard, the standard tire pressure for a spare tire is 2.4-2.5 bar. In winter, the tire pressure should be based on the standard tire pressure of the car tire, with an appropriate increase of about 0.2 bar. In summer, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will go out, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Generally, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. At this time, 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 light to turn on. In this case, simply perform a tire pressure reset. 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 port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure fault light to turn on. For sensor damage issues, only a new replacement part can be used.
