Do You Have to Pay for Tire Pressure Check at a Repair Shop?

[VonGraham]

Going to a repair shop to check tire pressure usually costs money, and it's more expensive at a 4S shop. However, checking tire pressure is a low-tech task, and general repair shops can handle it. Here is more information about tire pressure monitoring: 1. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is then transmitted from inside the tire to a central receiver module via a wireless transmitter, displaying the pressure data for each tire. 2. Indirect Tire Pressure Monitoring: The working principle of indirect tire pressure monitoring is that when the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors the tire pressure.
