1. A method of monitoring a pressure in a tire, which comprises:
- sensing a pressure prevailing in the tire or a temperature prevailing in the tire and outputting a sensor output signal; and
deciding whether the tire pressure is to be measured in dependence on a magnitude of a change in the sensor output signal.

Abstract
A tire pressure monitor and a method of measuring a pressure in a tire include a decision whether the tire pressure should be measured. The decision is made in dependence on a magnitude of a change in a signal which is output by a sensor which senses the pressure prevailing in the tire or the temperature prevailing in the tire. As a result it is possible to reduce the size and the weight of the components of a tire pressure monitor to be accommodated in the tire or in the rim to a minimum.
