What do the values on the tire pressure monitoring instrument indicate?

The values on the tire pressure monitoring instrument indicate the air pressure of the four tires, with the commonly used unit for tire pressure being bar. The functions of the tire pressure monitoring system are: 1. It will promptly alert when a tire is punctured, causing rapid or slow air leakage; 2. It will alert when tire looseness leads to unbalanced friction, causing the tire temperature to rise to 70 degrees Celsius, preventing a blowout; 3. It will alert when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing a temperature rise and subsequent blowout. The method to reset the tire pressure monitoring system is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle, press and hold the tire pressure monitoring button, and after 5 seconds, a beep will sound, then release the button to complete the reset.
I've been driving for over a decade, and the numbers on the tire pressure monitoring system indicate how strong the air pressure is inside the tires. The normal range is usually around 2.2 to 2.5 bar, with units in bar or psi depending on the vehicle's manual. If the pressure is too high, the tires become stiff, wear out faster in the middle, and braking can become unstable. If it's too low, the tires get soft, fuel consumption increases, and there's a risk of a blowout on the highway. My car's system displays bar, and in the morning when the car is cold, the reading is around 30, rising to 32 after driving for a while, which is normal. Regular tire pressure checks are crucial—I make it a habit to inflate them once a month. Last time on the highway, the pressure dropped to 1.9 and triggered an alarm, so I quickly pulled into a service station to fix it—it could have been dangerous otherwise. Maintaining proper tire pressure saves fuel and ensures safety, making driving much more reassuring. Tire temperature also affects the readings, with significant variations between winter and summer, so it's important to pay attention. Developing the habit of quickly checking the system ensures peace of mind when the numbers are stable before hitting the road.
When I first started driving, I didn't understand what the tire pressure monitoring numbers meant. Later, a friend who was learning to drive told me they were tire pressure readings, mostly measured in psi. My car recommends around 33 psi. If the value is above the range, the tires feel overly inflated and the ride becomes bumpy and uncomfortable; if it drops below, say 28 psi, fuel consumption increases and the edges of the tires wear out. Last week, the reading dropped to 26 psi, so I went to a gas station to refill the tires, which was an easy fix. The manual states that safe tire pressure significantly affects braking distance. If the value is too low, it must be addressed immediately to avoid air leaks and accidents. During my novice days, I ignored it once, resulting in a ruined tire and a big loss. Now, I check the readings before every drive to ensure they're within the normal range for peace of mind—a green light on the dashboard means it's OK. Remember to keep an air pump at home for easy pressure adjustments. Regular cleaning of the dashboard also helps for clearer visibility.
