Should I go to the 4S shop for a tire pressure warning after one month of new car use?

If a tire pressure warning appears after driving a new car for one month, there is no need to go to the 4S shop. When the owner is driving and notices a tire pressure warning on the dashboard, they should promptly pull over to a safe place, park the vehicle, and place a yellow triangle stand behind the vehicle to alert other drivers. If the vehicle is equipped with a tire pressure monitoring system, the tires should be checked. Tire pressure monitoring automatically and continuously checks the tire pressure while the car is in motion, alerting 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: Direct tire pressure monitoring devices use 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 readings 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 wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): This system combines the advantages of both direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and an indirect system for all four wheels. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time pressure data for all four tires as a fully direct system can.
I've encountered this situation quite a few times where the tire pressure warning light comes on after just one month of driving a new car. It could be due to uneven tire pressure settings from the factory or temperature fluctuations. I would first use a tire pressure gauge to manually check the pressure of each tire to see if it's within the range recommended in the owner's manual. If it's low, I'd try adding some air. Usually, after adding air, the warning light goes off, and then there's nothing to worry about. If the light remains on or the tire visibly looks flat, there might be a nail puncture or air leak, and it's best to head to the dealership immediately. Since the car is still under warranty, they'll inspect and fix it for free, which is both convenient and safe. Remember, don't drive with the warning light on—it's especially dangerous if a tire bursts on the highway. It's good practice to regularly check tire pressure, as beginners often overlook these small details.
