How to Handle a Tire Pressure Warning?
1 Answers
When a tire pressure warning appears and no visible damage is observed, you can simply inflate the tire to the normal pressure and reset the tire pressure system. If the tire is found to be punctured during inspection, drive to a tire shop promptly for a repair, then reinflate the tire. If the tire pressure warning reappears after inflation without any visible puncture, it might be due to air leakage caused by a deformed wheel rim; in this case, inspect the rim and consider replacing it. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to any leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure 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 shrink, making it rotate faster than the other tires. By comparing the rotational speed differences among the tires, the system monitors the tire pressure. Indirect tire pressure monitoring relies on calculating the rolling radius to assess the pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect monitoring. It equips two diagonally opposite tires with direct sensors and uses a four-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
