When beginning the mounting process on a clamp-in sensor, where should the valve stem be positioned?

In the mounting process of a clamp-in sensor tire, positioning the valve stem under the mounting head is crucial for several reasons. This position helps ensure that the sensor is properly aligned and that the mounting equipment can safely engage with the tire without risking damage to the sensor or the tire itself. When the valve stem is under the mounting head, it provides optimal access for tire changers to work without interference from the sensor, which is necessary for achieving the correct seating of the tire bead on the rim. Proper positioning also helps avoid any potential leaks or malfunctions that could arise if the sensor or valve stem were to become misaligned during the mounting process. Thus, placing the valve stem under the mounting head is essential for ensuring a successful installation and maintaining the functionality of the tire monitoring system.
