2. A sensor system for a tire, in which a sensor unit is installed in a tire'"'"'s air chamber, comprising:
-
a base which fixes the sensor unit in its installation position, the base being attached to the sensor unit;
a conductive path with a pair of contact points formed in the base, the conductive path connecting the contact points thereof; and
a detection circuit with a pair of contact points formed in the sensor unit, the detection circuit connecting the contact points thereof, and the contact points being arranged corresponding to positions of the contact points in the base, wherein a relative change in a distance between the sensor unit and its installation position is detected based on an open and closed state of the detection circuit.
