How to Read the Tire Pressure Gauge in a Car?

[DelJayla]

Automotive tire pressure gauges display the pressure in the inner black circle in BAR (indicating atmospheric pressure) or Pa (Pascal). Below is an introduction to tire pressure gauges: 1. Function of tire pressure gauges: A tire pressure gauge or automotive tire pressure gauge is a special type of pressure gauge designed specifically for measuring the pressure inside the tires of cars, trucks, bicycles, and other vehicles. Tire pressure gauges utilize pressure sensing technology, offering high measurement accuracy and a long service life. 2. Classification of tire pressure gauges: Pointer-type pressure gauges, where the elastic sensitive element inside the gauge undergoes elastic deformation under pressure, and the mechanical transmission amplification mechanism rotates the pointer to indicate the pressure value on the dial. The gauge also includes a zero-return device inside, which can keep the pointer at the indicated pressure value. Scale-type pressure gauges, where a piston with a scale moves under pressure and remains stable at a certain position, indicating the pressure value through the distance moved by the scale and the scale's markings.

Having been a driver for so many years, let me teach you a detailed method. Check the tire pressure gauge on your car—first, start the engine and wait for the dashboard to light up. Most cars display the tire pressure value on the instrument panel or center screen, measured in PSI or bar, typically between 28 and 35. For the exact normal range, refer to the owner’s manual or the label on the door frame. To operate, use the steering wheel buttons to navigate the info menu and select the tire option; the numbers will display in real time. If the tire pressure is too high, ride comfort suffers and braking becomes unstable; if it’s too low, fuel efficiency drops and the risk of a blowout increases. Always check tire pressure when the tires are cold—ideally after the car has been parked for several hours. If the gauge doesn’t display, it might indicate a faulty sensor or dead battery, so visit a repair shop promptly. Make it a habit to check tire pressure monthly—it saves fuel and enhances safety. Never ignore the tire pressure warning light; it’s a signal to take immediate action.

Dude, it's actually pretty easy. Start the car, and you'll see a tire icon on the dashboard. Tap it or use the menu button to switch to the tire pressure display. The values are in PSI, and around 30 is suitable for most cars. Too high and the ride will be bumpy and uncomfortable; too low and fuel consumption will increase or the tires may deform. I always check this screen display value, and it only takes a few minutes. If there are no numbers, make sure the car is running, as the sensors might need calibration. Checking cold tire pressure is more accurate, so measure it before heading out. Remember to refer to the label on the door frame for standard pressure, and don't rely on guesswork. With simple maintenance, you can avoid accidents on the highway.

To check the tire pressure gauge, observe the dashboard after ignition. The tire pressure value is usually displayed automatically in PSI, with the normal range being 30-35. Refer to the manual or the door frame for the standard pressure. High tire pressure reduces traction, while low pressure increases the risk of a blowout. It is recommended to check when the tires are cold to ensure accuracy. If the warning light is on, it indicates an abnormality, and you should visit a repair shop for a recheck. Regularly checking the pressure can prevent issues.
