1. A tire monitor comprising
an in-tire controller that stores a target inflation pressure representing the pressure to which said tire should be inflated
when said tire is at a standard temperature; and
a communication link for coupling said in-tire controller to a processor external to said tire,
wherein said in-tire controller transmits said target inflation pressure to said external processor when said external processor
is connected to said in-tire controller;
a sensor array comprising a pressure sensor and a temperature sensor mounted in said tire; and
a memory that stores sensor readings including said pressure and temperature values generated by said pressure sensor and
temperature sensor, respectively,
wherein said in-tire controller causes said temperature and pressure values to be stored in said memory and wherein said in-tire
controller transmits said stored pressure and temperature readings to said external processor; and
a motion sensor for generating a motion signal when said tire is moving.
