How to Determine Car Tire Pressure?

[Evelyn]

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.

As an experienced driver, I'm quite skilled at judging tire pressure. The first step is to prepare a reliable tire pressure gauge, with digital ones being more accurate. Measure cold tires in a quiet garage, checking each one. The pressure standard isn't what's printed on the tire surface, but rather the values in the manual or on the door label. Incorrect tire pressure can lead to poor handling, longer braking distances, and increased safety risks. I check every two weeks and adjust with an air pump if deviations are found. Also, pay attention to uneven tire wear, which may be related to pressure. Developing this habit can make your car more reliable and durable, easily extending tire life by five or six years.

Accurate tire pressure is crucial for safety. I believe using a tire pressure gauge to measure the pressure of each tire when the car is cold is sufficient. Too low pressure may cause a blowout, while too high pressure reduces grip and increases the risk of skidding in rainy conditions. Regular checks help prevent hazards, and I suggest measuring it when refueling. Correct tire pressure enhances handling stability and reduces accident risks. Don't underestimate this detail—it protects you and your family's lives.

From an environmental perspective, inaccurate tire pressure can increase fuel consumption by more than 10% and emit more exhaust. I use a tire pressure gauge to measure monthly, maintaining the recommended value. Cold tire readings are more accurate; adjusting when too high or low extends tire lifespan and reduces waste. Saving money while cutting emissions achieves two goals at once. Cultivating this small habit contributes to green transportation.
