How to Read a Car Pressure Gauge?

First, press the buckle and align it with the tire valve. Then push it forward all the way to secure the valve, and release the buckle. Finally, you can check whether the data value is within the normal range. For digital pressure gauges, the pressure value is displayed directly. Digital gauges usually have an activation button on the display. Press it once, and the screen will light up, which helps in low-light conditions. For this type of pressure gauge, pay attention to its measurement units. Common units include PSI and BAR. The normal tire pressure is 2.5 KG/cm².
I haven't been driving for long, and learning to read a tire pressure gauge is an essential skill. The tool is usually in the trunk. Find a flat spot to park, and make sure the tires have cooled for at least 10 minutes because hot tires give higher, inaccurate readings. Remove the valve cap and set it aside so you don't lose it. Press the pressure gauge firmly onto the valve stem until you hear a hiss of air, then hold it steady. The needle will stop at a certain point, like 30 PSI. The normal range is 28-35 PSI. If it's below 25, you should inflate the tires promptly to avoid excessive wear or a blowout. It's recommended to check once a month, and the most accurate readings are taken in the morning when the car is cold. An electronic gauge is more convenient, with an LCD screen that directly displays the number and has minimal error. Once you make it a habit, checking the pressure every time you wash your car can prevent problems before they arise—safe driving is that simple. New drivers will get the hang of it after a few tries, so don't stress, just go for it.
