Modern cars are increasingly equipped with TPMS (Tire Pressure Monitoring Systems), which act like a "smart bracelet" for tires, monitoring their health in real time. However, many auto repair shops may not be aware that this small system requires special attention when changing tires, particularly the valve stems (which are integrated with it).
How does TPMS work?
The TPMS sensor is typically mounted directly inside or on the underside of the valve stem. It transmits real-time tire pressure and temperature data to a receiver inside the vehicle via radio signals, which is then displayed on the dashboard.
Why is it important to check it when changing tires?
The sensor is fragile: improper use of a pry bar during tire removal or installation can easily damage this delicate electronic sensor. Once damaged, replacement is very costly.
The valve core degrades: Like regular valves, the rubber portion of a TPMS valve can degrade and crack over time. A degraded valve stem can cause a slow leak, rendering the TPMS system useless. Ensure the seal is intact: The sensor is secured to the rim by a metal seal. This seal can fail after repeated disassembly and assembly, leading to air leaks.
What are the best practices?
We strongly recommend that you replace the TPMS valve stem as a standard consumable item with every tire replacement. It's like getting a new pair of shoelaces when you buy a new pair of shoes. Doing so will:
Avoid risk: Prevent damage to expensive sensors due to handling errors.
Ensure a permanent solution: Ensure the new valve stem seals perfectly, eliminating leaks for years to come.
Increase service value: Show your customers your professionalism and attentiveness, making this service completely reasonable and worthwhile.
