How to Remove and Install Tires with Tire Pressure Monitoring?
3 Answers
First, remove the tire. When pressing the tire, we usually start by locating two points on the outside and two points on the inside to separate the tire bead from the rim. While locating these points, it's crucial to avoid the tire pressure sensor. Generally, choose two points that are 90 degrees from the valve stem. After pressing, secure the tire on the turntable and prepare to remove it. Start by prying the outer bead of the tire off the rim. When prying the tire, ensure the tire pressure sensor (valve stem) is positioned about 20 cm ahead of the pry bar's lifting point (rotate clockwise).
Last time I replaced tires with TPMS (Tire Pressure Monitoring System), I had to be extra careful about the sensor positions to avoid damaging them. For most vehicles, the sensors are located near the valve stems—mark the tire positions before removal for easier reassembly. Use a professional tire changer and gently pry from the inner side of the rim, avoiding brute force to prevent damaging the sensor diaphragms. After removal, check if the sensor screws are loose or corroded; clean or replace them if needed. When reinstalling, ensure even application of sealant and inflate slowly to avoid pressure shocks to the sensors. Finally, start the car to let the system self-check—sometimes it takes a few kilometers of driving for the TPMS to reset. Remember to maintain the rim sensors regularly, as dust buildup can affect accuracy. This job is best done in a clean workshop—DIY at home carries risks, like injury from improper tools or misread tire pressure values.
The key to dismounting tires with TPMS is to protect the sensors from damage. I usually start by loosening the valve core with a wrench and marking its original position for easy reinstallation. When prying the tire off, do it gently, using a lever-type tire tool to lift the rim edge from the inside out, avoiding the sensor area. If the sensor has an aluminum housing, wipe off any oxide with a soft cloth. Before mounting the new tire, check the O-ring for cracks—replace it if aged. After inflation, wait a few minutes for the system to initialize, then test-drive to verify the dashboard display. From my experience, cleaning the inner rim after dismounting extends sensor life. To save money, you can rent tools and DIY, but beginners shouldn’t risk it—damaged sensors cost hundreds to replace, so visiting a professional shop is wiser.
