How to Measure Car Tire Pressure?
2 Answers
Methods for measuring car tire pressure: 1. Quickly screw the copper nozzle of the pressure gauge onto the tire valve; 2. Observe the reading on the pressure gauge, using the inner scale as the reference, which is marked with numbers like 1, 2, 3, 4, 5, 6, 7. These numbers represent multiples of standard atmospheric pressure. For example, 2 means twice the standard atmospheric pressure; 3. Remove the pressure gauge to read the value, as it functions similarly to a stopwatch, with the needle fixed at the measured pressure value. During tire usage, tire pressure is a crucial indicator. Both excessively high and low tire pressure can cause unnecessary wear and shorten the tire's lifespan. Driving with low tire pressure can lead to increased fuel consumption, accelerated tire wear, wheel rim deformation, and potential blowouts. Conversely, excessively high tire pressure may reduce tire grip, weaken braking performance, and increase the risk of blowouts.
I've been driving for decades, and checking tire pressure is a piece of cake for me. You need to wait until the tires are completely cooled down before doing it, like after the car has been parked overnight. Find a reliable tire pressure gauge—I recommend a digital one for better accuracy. Unscrew the valve cap on the tire, press the gauge head firmly onto it, hold it steady for a few seconds, and then read the pressure value. Compare it with the manufacturer's recommended pressure—usually, there's a label on the driver's side door frame showing the PSI value. If it's too low, use an air pump to inflate it to the correct level; if it's too high, release some air, but don't overdo it. I always remind my family never to overlook this because insufficient pressure can lead to blowouts, increased fuel consumption, and even uneven tire wear, shortening their lifespan. Make it a habit to check once a week, especially before long trips—it saves trouble and money. Just keep a good-quality portable tire pressure gauge in the trunk; it's affordable but practical, and don't wait until problems arise to regret it.
