17. Tire
removal
TPMS-equipped wheels with internal sensors must be handled with great care during
tire removal and installation procedures. A suitable tire changer and proper bead
lubrication will greatly facilitate these operations.
Test sensor for proper operation before proceeding.
17.1. Breaking the bead
Remove valve cap and insert and wait until tire deflates before breaking the bead.
Many bead breakers use a blade to break the bead loose from the wheel; with this
kind of equipment, position the wheel so the sensor is at 6 o'clock before beginning.
If the bead does not break loose at the first attempt, remember to insert the bead
breaker blade away from sensor body throughout the procedure. If you are using a
bead breaker with rollers, make sure the roller will not push the bead into the wheel
well or the bead might hit the sensor during rotation.
If you are using a blade-type bead breaker, make sure the blade is
well away from the sensor. Otherwise, the blade might push the tire
bead into the wheel and it might contact and damage the sensor.
