Abstract: A method for encapsulating a monitoring device for a pneumatic tire, wherein the monitoring device includes a threaded rod and a pressure sensor, includes the steps of positioning the monitoring device in an encapsulation chamber of an encapsulation device with a portion of the threaded rod extending from the encapsulation chamber; engaging the threaded rod against the encapsulation device to suspend the electronic monitoring device within the encapsulation chamber; and filling the encapsulation chamber with encapsulation material to encapsulate the monitoring device to form an encapsulated monitoring device. The encapsulated monitoring device may be mounted to a pneumatic tire with an attachment patch.
