El-Watch has developed the Tap & Tell solution for easier management of tire health than ever before. Use the app to activate the Tap & Tell mode, then hit the tire gently with a hammer. The sensor detects the impact, and it is registered in the correct position on the vehicle. This implies that the sensors may be fitted inside the tire before mounting it on the vehicle, and there will be no confusion about which sensor is in which tire. This also simplifies the change between summer and winter tires.
