1. A pressure monitoring system for a plurality of tires installed on wheels of a motor vehicle, the motor vehicle being potentially assembled from component sections including tractor and trailers, the pressure management system comprising:

  • a plurality of tire pressure sensors mounted in communication with tires mounted to the wheels of the motor vehicle to provide tire pressure measurements;

    an ambient temperature sensor providing temperature measurements;

    a vehicle velocity sensor providing vehicle velocity measurements;

    a real time source; and

    a body computer installed on the vehicle coupled to receive the tire pressure, ambient temperature and vehicle velocity measurements and having access to the real time source, the body computer including cold leak detection programming providing norms in terms of a target tire pressure at a defined temperature and responsive upon execution to the target tire pressure, an initial tire pressure measurement and an initial ambient temperature measurement for adjusting the initial tire pressure based on initial temperature before comparing the tire pressure to targets.
