What is the standard air pressure of car tires?

It is normal for the tire pressure to be between 2.3 and 2.5. If the seat is full (5 people), it is more appropriate to adjust the tire pressure to about 2.5; Generally speaking, the tire pressure value of two people is normal at 2.3.

Standard air pressure can usually be found in the following places: the owner's manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, and the door of the fuel tank cover.

How much tire pressure should be hit, subject to the recommended value of the car factory. This is because the setting of tire pressure mainly considers vehicle factors such as body weight and chassis height. It is not necessarily related to what brand of tires are used.

Always check the tire pressure to ensure safety.

1. Observe the tire condition before going out. Radial tires-that is, low-pressure tires, as long as the flatness is not too low, it is normal to feel great elasticity under the pedal. High pressure tire-bias tire with inner tube. From the front, the shoulder position of the tire is not prominent, which is commonly known as "no cheeks". Seen from the side, the contact area with the ground is almost normal.

2. Pay attention to the friction between the tire and the ground when driving, feel the buffering force when the road surface is not very flat, and feel whether the acceleration has changed compared with usual when refueling. These are all accumulated experiences.

3. Under normal circumstances, go to a professional tire repair shop every week to check and replenish the air pressure.
