1. A cornering force calculating method of calculating a magnitude of a cornering force to be applied to each of a plurality of wheels provided to a vehicle when the vehicle is cornering, the plurality of wheels being each assembled with a tire, the cornering force calculating method comprising:

  • a centrifugal force measuring step of measuring a magnitude of a centrifugal force to be applied to the vehicle which is cornering, the centrifugal force being in a direction substantially orthogonal to a vehicle traveling direction;

    a contact length deriving step of determining a contact length in a wheel circumferential direction, at a contact portion of each of the plurality of wheels of the vehicle which is cornering;

    a width direction deformation amount deriving step of determining an amount of deformation in a wheel width direction, at the contact portion of each of the plurality of wheels of the vehicle which is cornering; and

    a cornering force calculating step of calculating a magnitude of a cornering force generated in each of the plurality of wheels provided to the vehicle, based on the magnitude of the centrifugal force, the contact length, and the amount of the deformation in the wheel width direction.
