When separating bead from the wheel, you must locate the tire pressure sensor at ______ from the bead breaker?

• A. 180 degrees
• B. 0 degrees
• C. 90 degrees
• D. 270 degrees

Answer: (A)

When separating the bead, protect the tire pressure sensor by keeping the bead breaker opposite the sensor around the wheel. Positioning the tool 180 degrees away from the sensor places the contact point on the opposite side of the rim, reducing the chance of striking or damaging the sensor as you work the bead loose all the way around. Placing the bead breaker closer to the sensor (0, 90, or 270 degrees) raises the risk of contact with the sensor and its wiring, which can lead to damage or malfunction. So, the bead breaker should be located opposite the sensor, about 180 degrees away.
