The air pressure of a non-full-size spare tire is generally almost appropriate.

The air pressure of a non-full-size spare tire is generally almost appropriate.

During the driving process, the tire wear is the most serious, and it will inevitably damage the tire suddenly, so every car will be equipped with a spare tire when it leaves the factory. So what is the general pressure of a non-full-size spare tire?

Usually, the pressure of a non-full-size spare tire is generally 4.0bar.

The reason why the tire pressure of the spare tire is high is that if the spare tire is stored for a long time, it may be exhausted slowly to prevent the tire pressure from being insufficient, so the tire pressure of the spare tire is generally higher than the standard tire pressure, and it will be adjusted to the appropriate tire pressure when the spare tire is needed.

Both the tire pressure value recommended by the manufacturer and the tire pressure value of the spare tire can be found in the owner's manual, the door of the fuel tank cover and the bottom of the B-pillar after the door is opened. In addition, the car should pay attention to the fact that when using a non-full-size spare tire, the maximum speed cannot exceed 80km/h, and the distance traveled by the car cannot exceed 100 km.
