What are the reasons for the Audi showing insufficient tire pressure after just replacing the tires?

The reasons for the Audi showing insufficient tire pressure after just replacing the tires include a leaking tire valve, tire damage, deformed wheel rims, long-term overloading of the vehicle, and differences in tire quality. If the tire valve is leaking, it should be repaired or replaced promptly. If no damage is found during inspection, you can directly inflate the tire to the normal pressure and reset the tire pressure system. If the inspection reveals that the tire has been punctured, drive to a tire shop promptly for a repair and then reinflate the tire. If the system indicates insufficient tire pressure some time after inflation, but there is no puncture, it may be due to air leakage caused by deformed wheel rims. Deformed rims can also reduce the sealing performance of the tire. It is recommended to check the rims and replace them if necessary. Long-term overloading of the vehicle can cause uneven tire pressure distribution, so avoid carrying excessive weight. Differences in tire manufacturing processes can lead to insufficient tire pressure due to thermal expansion and contraction. It is advisable to choose higher-quality tires.
As a friend who often drives an Audi, I've encountered this situation several times. Just after changing tires, it shows insufficient tire pressure, possibly because the new tires weren't inflated enough during installation, the mechanic carelessly missed checking the pressure, or a loose valve stem caused a slight leak. Another important reason is that Audi's tire pressure monitoring system requires a manual reset, such as through the central control screen menu, otherwise it might mistakenly report an issue thinking the tire specifications have changed. Weather changes are also a factor; colder temperatures naturally lower tire pressure, triggering the alarm. The solution is simple: first, use a tire pressure gauge to check the actual pressure, and if it's low, fill it to the standard value, then reset the system. Safety should never be overlooked; ignoring it could affect handling or even lead to a blowout. By the way, after changing tires, it's best to let the car idle for a while to allow the sensors to calibrate. This can help avoid false alarms.
