Abstract: An arrangement for provision of vehicle tire sensory information while a tire (12) is mounted on a wheel rim (10) of a vehicle. A sensor unit (16) includes a tire condition sensor (e.g., electronics 38), a signal transmitter (36), and a housing (20) that contains the sensor and the transmitter. The housing (20) has a mounting hole. A stud (18) is welded to the rim (10) and extends into the space bounded between the tire (12) and the rim (10). The stud extends through the mounting hole of the sensor housing (20). A retainer (e.g., 26) extends between the sensor housing (20) and the stud (18) such that the sensor housing is held fixed relative to the stud.
