installed inside the wheel on the metal valve; the tire pressure
and temperature values are transmitted and evaluated

electronics installed inside the wheel. With the help of the ABS
sensors, the TPMS compares the speed and rolling circumference
of the individuals wheels. The loss of pressure is determined
indirectly. If there is a change in the tire pressure, then the
speed and the rolling circumference of wheel will also change. |
