How to Check Tire Pressure in a Car?
1 Answers
If the vehicle is equipped with a built-in tire pressure monitoring function, the tire pressure can be viewed on the car's dashboard. If the vehicle does not have a built-in tire pressure monitoring function, there will be a tire pressure warning. The user manual, the driver's door (near the car's B-pillar), and the fuel tank cover also display the standard tire pressure. Different brands and models may have varying tire pressure requirements. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure while driving, alerting the driver in case of tire leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in faster rotation compared to the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both direct and indirect monitoring. It is equipped with direct sensors in two diagonally opposite tires and a four-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.
