1. A computer program with a program code, stored on a computer readable medium and executable by a computer system, for performing a method of monitoring the tire pressure in a vehicle tire, in which temporally successive tire pressure measured values are sensed by a pressure detector, and at least part of the tire pressure measured values is transmitted from a transmitter to a receiver with a variable frequency of occurrence, wherein the frequency of occurrence is derived from the sensed tire pressure measured values, the computer program comprising:

  • instructions for decrementing or incrementing a count of counter beginning with a starting value;

    instructions for comparing the count with a tire pressure change dependent parameter derived from the sensed tire pressure measured values; and

    instructions for triggering a transmission when the count reaches the tire pressure change dependent parameter.
