Where to look when the pressure gauge shows 2.5?

The pressure gauge shows 2.5, look at the black dial on the pressure gauge, which is a dial displaying numbers from 1 to 7. A pressure gauge is an instrument used to measure air pressure, and there are various types. Among them, a tire pressure gauge is specifically designed for measuring the tire pressure of small vehicles such as micro cars and motorcycles. Methods to check the pressure: 1. Hold the buckle and align it with the wheel's air valve; 2. Push it forward to the end to secure the air valve, then release the buckle; 3. Digital gauges usually have an activation button on the display. Press it to light up the screen, which is helpful in low-light conditions; 4. Check if the data value is within the normal range. Digital pressure gauges directly display the pressure value.
When I first started driving, I was also confused when I saw the tire pressure value on the dashboard showing 2.5 bar. Later, I learned some car knowledge and realized this is a common unit for tire pressure, usually around 30-36 PSI. To determine if it's appropriate, the first thing is to check the vehicle's recommended value—open the car door and look for the small label on the door frame or B-pillar, which indicates the standard tire pressure for the front and rear wheels. Most family cars have a recommended range between 2.2 and 2.5 bar. If the displayed value is too high or too low, it's not good; if it's too high, the tires will wear out faster, the ride will be bumpier, and fuel consumption will increase; if it's too low, the tires will be flat, making driving unstable. I suggest not rushing—find a time when the car is cold (after being parked for a few hours) and use a simple tire pressure gauge to check, ensuring the value matches the recommended one. Make it a habit to check once a month—it's safer, extends tire life, and saves a lot of money on tire replacements.
