How to Determine Car Tire Pressure?
2 Answers
Methods for determining car tire pressure: 1. Unscrew the tire valve cap, press the tire pressure gauge firmly onto the valve stem (must press all the way down), observe the pointer to read the measured pressure value, and compare it with the standard tire pressure; 2. Use a dedicated pressure gauge to check the tire pressure. If the pressure does not meet the standard, it indicates a fault. If the pressure is below the specified value, inflate the tire to the standard value; 3. If no pressure gauge is available, observe the tire wear condition to determine the tire pressure level. When pressure is low, both sides of the tread make greater contact pressure with the ground, causing severe wear on both sides. When pressure is high, the central part of the tread makes greater contact pressure, resulting in severe wear in the middle.
I usually pay great attention to tire pressure checks when driving, as it directly affects safety and fuel consumption. The tool is very simple—just use a portable tire pressure gauge, which can be bought cheaply at gas stations or online. Make sure to measure when the car is cold, meaning check it after the car has been parked for a few hours without being driven. Unscrew the valve cap, press the tire pressure gauge onto it, and the reading will display. Refer to the sticker on the door frame B-pillar for the standard, which shows the manufacturer's recommended pressure value, such as around 30 PSI. If the tire pressure is too low, the tires will wear out faster, fuel consumption will increase, and driving will be unstable; if it's too high, the tires will become stiff and prone to accidents. I make it a habit to check once a month and adjust with seasonal changes—slightly higher in winter. Regular checks can save fuel costs and prevent blowouts.
