What is TPMS?
Tire pressure monitoring systems (abbreviated to RDKS, RDK or RDC) or tire pressure monitoring systems (TPMS) are used to monitor tire pressure in motor vehicles in order to prevent accidents caused by incorrect tire pressure. In addition, with the optimal tire pressure, fuel can be saved and unnecessary tire wear avoided. A distinction is made between direct and indirect systems.

Since November 2014, all newly registered cars and mobile homes must be dated Vehicle manufacturers are equipped with a tire pressure monitoring system!
Do you have a direct or indirect tire pressure monitoring system?
If the tire pressure of all 4 tires is shown on the display, you most likely have a direct system. This is because the indirect method cannot differentiate between the individual tires, but can only determine a general change in driving behavior. If you are not sure, please contact your vehicle manufacturer.
Direct tire pressure monitoring system: In the direct system, electronic sensors are located inside the tire. These permanently measure the air pressure and the air temperature of the tires. In the event of a pressure loss, the driver is informed immediately via the vehicle display.
Indirect tire pressure monitoring system: There are no sensors in the wheel here. The indirect system records the tire pressure via the speed frequency of the wheels. The speed is recorded by the ABS system. If the speed characteristics of the tires change, an alarm is sounded. Direct tire pressure monitoring system: With the direct system, electronic sensors are located inside the tire. These permanently measure the air pressure and the air temperature of the tires. In the event of a pressure loss, the driver is informed immediately via the vehicle display.
