Where to Check Tire Pressure Monitoring?

Tire pressure monitoring can be viewed on the vehicle's onboard computer or central control screen. Tire Pressure Monitoring System (TPMS) automatically monitors the tire pressure in real-time during driving and alerts the driver in case of tire leakage or low pressure to ensure driving safety. When the tire pressure is too high, it reduces the contact area between the tire and the ground. There are two types of tire pressure monitoring methods: 1. Indirect TPMS: It works by detecting when the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, it monitors the tire pressure. 2. Direct TPMS: It uses pressure sensors installed inside the tires to directly measure the tire pressure and transmits the pressure information wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire.
Where to check the tire pressure monitoring was something I couldn't figure out when I first bought my car. Later, I found it's usually on the dashboard - the tire pressure values might pop up for a few seconds when starting the vehicle. While driving, you need to switch display modes using steering wheel buttons to see it. My neighbor's domestic brand car is more intuitive, with a small tire pressure icon displaying real-time data on the central control screen's main interface. If a yellow exclamation mark plus tire icon suddenly lights up on the dashboard, that's a tire pressure abnormality warning - you should check it immediately. Some older cars don't have this feature and require manual measurement with a tire pressure gauge, but nowadays most new cars come with this as standard equipment, which is quite convenient.
