Why is it not recommended to install tire pressure monitoring for new cars?

Most new cars basically come with original tire pressure monitoring devices, and some models even have tire pressure warning devices. Tire pressure monitoring is not a real-time monitoring function. If there is an abnormality in the tire, information will be automatically displayed on the dashboard. The displayed content does not have specific values, only indicating which tire has a problem. The working principle of tire pressure monitoring is: Using pressure sensors installed in the tires to measure the tire pressure, and using wireless transmitters to send the pressure information from inside the tire to the central receiver module. How to eliminate the tire pressure alarm: There is a tire monitoring indicator button on the central console. After the system issues a low tire pressure warning, the car must remain stationary for about one minute. Do not move the car or turn off and restart the ignition switch until the button is pressed to recalibrate the tire monitoring indicator. Find the tire pressure reset option in the settings on the central display. If none of the above methods work, you need to go to a 4S shop to eliminate the tire pressure alarm. What to do if the tire pressure is insufficient: If no damage is visible, you can directly inflate to the normal tire pressure and reset the tire pressure system. If the tire is found to be punctured during inspection, you need to drive to a tire shop promptly for repair and then reinflate. If the tire pressure is still indicated as insufficient after inflation for a while, but there is no puncture in the tire, it may be due to air leakage caused by wheel hub deformation. It is recommended to check the wheel hub and replace it.
I've been in the auto repair industry for over a decade. New vehicles typically come equipped with factory-installed tire pressure monitoring systems (TPMS), which are precisely designed and fully compatible with the vehicle's computer, making additional installations redundant. Manually adding aftermarket TPMS may interfere with the original system's signals, leading to false alarms or malfunctions – for instance, sensor conflicts can trigger incorrect pressure readings, actually increasing safety risks. The installation process itself may damage tire valves or wiring, creating potential air leaks that are complicated and costly to repair. We recommend owners trust the factory settings and simply perform regular tire checks. If installation is absolutely necessary, choose professional shops to ensure proper calibration, though most new vehicles don't require this at all – saving both money and hassle while avoiding unnecessary complications. While tire pressure monitoring is crucial for safety, redundant systems often create more problems than they solve.
I've driven several new cars that came with built-in tire pressure monitoring systems, eliminating the need for aftermarket installations. Once, I tried installing a cheap third-party system, only to end up with constant false alarms. After repairs, I learned it was due to a wiring short circuit. As a car owner, I believe this is purely a waste of time and money. The original systems in new cars undergo rigorous manufacturer testing for optimal compatibility; additional devices may cause malfunctions and compromise driving safety, such as false alarms causing panic on highways. Stick with the factory-installed system and simply check tire pressure during annual maintenance—it's straightforward and reliable. Safety comes first; don't complicate things for yourself by adding unnecessary gadgets.
