What Do the Two Numbers in Tire Pressure Display Represent?

[BryceDella]

The two numbers in the tire pressure display represent the minimum and maximum values of the tire pressure. This is because tire pressure is not fixed; it can fluctuate as the wheels rotate, and even when the vehicle is stationary, tire pressure can increase in hot weather. In other words, tire pressure can change. There are generally three reasons for abnormal tire pressure: Abnormal Tire Pressure: The system typically alerts when the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. 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 previously recorded data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged Tire Pressure Sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can trigger the tire pressure warning light. In such cases, the only solution is to replace the sensor with a new one.

When I first bought the car, I noticed there were two numbers displayed for the tire pressure. Actually, they represent the vehicle's real-time tire pressure and the recommended tire pressure. One number shows the actual current pressure in the tires, while the other is the ideal pressure value set according to the car manual or the door label, usually measured in PSI or kPa. Both too low and too high tire pressure are bad. If it's too low, the tire friction increases, leading to faster wear and higher fuel consumption. If it's too high, it affects traction and may cause a blowout. I remember last time on a long trip, when the numbers were way off, I immediately found a roadside auto repair shop to adjust it, ensuring safety. For daily driving, I check regularly, usually once a month. Maintaining proper tire pressure can save fuel and extend tire life. I recommend all new drivers develop this habit.

The two numbers displayed for tire pressure are understood as the current pressure and the recommended value, which are of great significance as they relate to driving safety. The actual pressure refers to the current inflation level of the tire, while the recommended value is the ideal range set by the manufacturer, usually indicated on a label near the door. If there is a significant difference between the two numbers, such as a difference of more than 10 PSI, insufficient tire pressure can cause tire deformation and increase the risk of a blowout, especially during high-speed driving, which is particularly dangerous. I always worry about this when driving, so I frequently check the display and adjust the pressure to ensure each tire is balanced. It's best to keep a tire pressure gauge handy for self-measurement or to visit a professional shop for inspection—never overlook this point.

When I was learning to drive, I was told that the two numbers displayed for tire pressure refer to the real-time pressure and the recommended pressure. The real-time value is the current pressure monitored by the dashboard, while the recommended value is usually around 30-35 PSI depending on the vehicle model. When the difference between them is too large, I take immediate action, such as inflating the tires to prevent air leaks. Proper tire pressure not only ensures a stable ride but also saves fuel. I once experienced an abnormal display, which turned out to be a slow leak, and fixing it in time saved me the cost of replacing the tire. Remember, regularly checking these two numbers can prevent major issues.
