Why would tire pressure light come on after getting new tires?
Each tire’s pressure sensor is housed in the valve stem. A few minutes after you start up the car, each one communicates, wirelessly, with the car’s computer. 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.
