A tire inflation gas telemetry system (30) is installed inside a tire (174) mounted to a wheel (170) and is placed within a protective housing (100) having pneumatic cylinders (116, 126) with piston rods (128, 130) that are extended or retracted by tire inflation gas pressure changes. The housing is suspended by a cable (156) slung around the wheel. The cable is slack or taut depending on motion of a first piston rod, and the telemetry system is pivoted into alternate protected and operational orientations by motion of a second piston rod. When the tire is uninflated, the cable is slack, and the telemetry system is pivoted into the protected orientation. As the tire is inflated, the cable becomes taut causing the housing to be drawn tightly against the wheel, and the telemetry system is pivoted into the operational orientation.
