1. A system of estimating a load bearing on a vehicle tire, comprising:

  • a vehicle tire having a tire cavity and supporting a load;

    an inflation pressure measuring sensor attached to the tire for measuring an inflation pressure level within the tire cavity;

    a contact patch length sensor attached to the tire for measuring the contact patch length of the tire rolling against a ground surface carrying a tire load;

    a tire rolling speed sensor mounted to the vehicle for measuring a rolling speed of the tire;

    a tire wear state estimation calculator for estimating a tire wear state of a tread of the tire; and

    a tire load calculator for estimating a tire load from the contact patch length, the inflation pressure level, and the tire rolling speed;

    the tire load calculator in the estimation of the tire load operably utilizing as a compensation factor input the estimated tire wear state.
