What is the normal tire pressure and how to check it?

Normal range of tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. How to check it: The tire pressure monitoring indicator light will illuminate if the tire pressure is abnormal, and it will remain off if the pressure is normal. The tire pressure monitoring indicator is a yellow symbol, resembling an irregular circle with no top seal, four small spikes at the bottom, and an exclamation mark inside. The illumination of this light indicates abnormal tire pressure. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will typically alert when the pressure is below 1.8bar or above 3.0bar. In such cases, the tires should be inspected and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to display the previous data, causing the indicator light to illuminate. Simply reset the tire pressure monitoring system to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors the tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
I always pay close attention to tire pressure when driving because high pressure causes faster tire wear, while low pressure increases the risk of blowouts, which is very unsafe. Normally, most family cars have a recommended tire pressure between 32 to 35 PSI, but the exact value should be checked in your car's manual or on the small sticker by the door. How do you check tire pressure? The simplest way is to use a handheld tire pressure gauge—just spend a few dozen bucks to buy one and keep it in your car, testing the pressure every month or two before inflating. Newer cars also have a dashboard indicator light that turns on when the pressure is off. Remember, measuring pressure when the tires are cold gives the most accurate reading. Low tire pressure increases fuel consumption, while excessively high pressure may affect braking stability, so making a habit of monthly checks can save you money and reduce risks.
As someone who just got my driver's license, I didn't know much about tire pressure at first. The normal range is about 32 to 35 PSI, but my car recommends 34 PSI. There are several ways to check it: first, use a tire pressure gauge tool by pressing it onto the valve stem to get a reading; second, if the vehicle has a tire pressure monitoring system, a warning light will illuminate after startup if there's an abnormality. If the tire looks flat, the pressure is definitely low, but don't rely solely on visual inspection—measure it properly. Both too high and too low pressure can cause discomfort. My friend's fuel consumption doubled after underinflation, so now I manually check my tire pressure every week.
