So how do you not damage the TPMS?? This will be good for when I need new tires. Thanks
You can avoid the valve stem area when breaking the bead and remove the sensor after you lever off the first bead as per the manual instructions.
Section 10-16 and 10-17"○Lightly break the air valve portion [A] of the bead.
CAUTION
Do not deep break the air valve portion of the bead
to prevent damage to the tire pressure measurement
sensor.
CAUTION
Be careful not to scratch the tire pressure measurement
sensor.
○Pull the opposite bead of the tire [A] upward.
○
Unscrew the bolt and remove the tire pressure measurement
sensor [C], spring and air valve.○Step on the side of the tire opposite the air valve, and start
plying the tire off the rim near the air valve with tire iron.
Any scratch may damage sensor."
When levering the second bead off the rim the bead tends to catch on the sensor if you don't take care to avoid it and it could easily break.
The first 5 or 6 tire changes I did I removed the sensor as instructed. But I eventually got good enough at tire changing that I no longer bother.
