TPMS Sensors typically need to be replaced for one of the following three reasons:
Battery Life – Estimated life of 5 to 10 years or 100k miles
Damage – Caused by accidents, pot holes, etc
Corrosion – Typically from road salt (cold weather climates) or galvanic corrosion
Note: It typically makes sense to replace all sensors at once since batteries have similar life spans
Should I replace my TPMS sensor when replacing my tire?
If the new set of tires is expected to cross over the TPMS battery threshold consider replacing the TPMS Sensors now to avoid tire mounting fees
Otherwise TPMS manufacturers recommend using a service kit to replace TPMS components to prolong life
