How to Determine if Car Tire Pressure is Normal?
2 Answers
Methods to determine normal car tire pressure: 1. Locate the standard tire pressure value in the maintenance manual or on the inside of the car door, usually referring to the half-load tire pressure; 2. Unscrew the tire valve cap and press the tire pressure gauge onto the valve stem, ensuring it is pressed all the way down; 3. Observe the pointer and read the measured tire pressure value; 4. Compare the measured value with the standard tire pressure. If the pressure is too high, press the deflation valve button on the tire pressure gauge. If the pressure is too low, inflate the tire promptly. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage can lead to the end of the car's life. Tire pressure is the blood pressure of the car, and its level plays a crucial role in the car's performance and power.
To ensure proper car tire pressure, I make it a habit to check before every long trip. Tires tend to soften in cold weather and expand in summer, so I always check them in the morning when the car hasn't been moved—that's when the readings are most accurate. I use a simple tire pressure gauge pressed onto the valve stem to get the reading. If it's low, I quickly top it up with a pump; if it's high, I release a bit of air. Most cars have a small label near the driver's door with the standard pressure value. I usually keep it 2-3 psi below that as a safety buffer—too high risks a blowout, while too low increases fuel consumption. An extra tip: check the spare tire's pressure every two weeks, as many people forget about it. Developing this habit can save about 10% on fuel and prevent unexpected expenses from premature tire wear—it's truly a win-win.
