How to Check Tire Pressure on the Tire?
2 Answers
To check the tire pressure on the tire, you can use a tire pressure gauge or an air pressure gauge. First, ensure that the center line of the gauge's measuring port forms an angle of 90 to 180 degrees with the axis of the gauge body. When observing, align the pointer with the mirrored pointer; the value indicated by the pointer at this point is the pressure reading, accurate to one decimal place. When the measuring end of the pressure gauge is pressed firmly against the tire's valve stem, the gauge's pointer will deflect, and the indicated value is the tire's inflation pressure. The greater the internal pressure, the more the pointer deflects. Nowadays, more and more cars are equipped with tire pressure monitoring systems, which can display the tire pressure directly on the dashboard.
Checking tire pressure is quite simple. As someone who has been driving for over a decade, I particularly enjoy using a digital pressure gauge. The most accurate readings come when the vehicle is parked and the tires are cold. Simply remove the small plastic cap from the valve stem, firmly press the gauge onto the valve, and the reading will appear instantly. Then compare it with the recommended pressure value, usually listed in PSI on the label inside the driver's door. If the pressure is low, use an air pump to add some air; if it's high, press the valve to release some. Remember to check regularly, especially during seasonal changes. For instance, tires tend to lose air in winter, and low pressure can increase fuel consumption, reduce handling stability, and even lead to dangerous blowouts. Keeping a small pressure gauge in your car is very convenient – just check once a month.
