1. A passenger car tire pressure monitoring system (TPMS) comprising:

  • a processor, wherein the processor is configured to;

    determine a safety condition of a specific tire of the passenger car, based on deviations from a load-dependent tire pressure standard that is configured dynamically based on a real-time load of the specific tire measured by at least one load sensor; and

    determine the load-dependent tire pressure standard by looking up a database comprising a plurality of tire pressure standards correlating respectively with a plurality of loads for the specific tire;

    an indication device configured to provide at least one of a visual, audio, or heptic indication of the safety condition of the specific tire; and

    a plurality of sensors configured to collect data of the tire load;

    wherein;

    the safety condition comprises a tire deformation limit;

    the TPMS is a non-FMVSS138 system; and

    the plurality of sensors are disposed at seats of the passenger car to measure occupancy of the passenger car to thereby indirectly measure the tire load data.
