| (1) TPMS indirect measuring. There are no wheel electronics installed inside the wheel. With the help of the ABS sensors, the TPMS compares the rolling circumference of the individual wheels. The loss of pressure is determined indirectly. If there is a change in the tire pressure, then the speed of the tire will also change. (2) TPMS + indirect measuring. There are no wheel 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. (3) TPMS direct measuring. The wheel electronics are installed inside the wheel on the metal valve; the tire pressure and temperature values are transmitted and evaluated periodically. | |||

Note. Be careful not to scratch off the glued- on wheel trim on these rims. The surface of the wheel trim is very sensitive. The rim will have be replaced if the wheel trim is damaged. The wheel trim cannot be replaced.
