Do you have to replace TPMS sensors with new tires?
Most tire shops and repair shops recommend servicing the TPMS after changing or installing new tires or wheels by replacing the valve core, retaining nut, seal and cap on the valve stem, then testing the system to make sure it’s operating correctly. The indirect type uses antilock brake sensors to detect wheel speed.
Why is my tire pressure light on with brand new tires?
RAY: One of your tire-pressure sensors is bad, Patsy. Each tire’s pressure sensor is housed in the valve stem. If the pressure is low, the computer makes the dashboard light go on. Or, if one of the sensors does not communicate at all, that also makes the light go on.
How does the tire pressure monitor work on a Toyota 4Runner?

The initialization process is completed when the signals from the 5 tires have been received.
What kind of tires do Toyota 4Runners use?
Tires and wheels are installed that are not equipped with a tire pressure sensor. Snow tires or tire chains are used. l The battery of the sensor has been depleted. Wheels other than manufacturer factory wheels are used.
