Problem to be solved: to provide a system, a method and a program for quantitatively evaluating high speed direct straightness stability of a tire by an on-board test.System 1The acquisition section 10 for acquiring the measured value by the on-board test apparatus 20 andLag angle δ Cornering stiffness calculation unit 11 which calculates the core stiffness CS (f) with CF.Using the joint stiffness CS (f) calculated for each front wheel tire and rear wheel tireYaw rate steady gain G ψ A constant gain calculating section 12 for calculating (0) andLag angle for front wheel tires δ An alignment torque stiff calculation unit 13 for calculating alignment torque stiffness ATS (f) with SATYaw rate steady gain G ψ Ratio of (f) of alignment truthfulness (0) to (0). ψ A quantitative evaluation value gat / ψ A quantitative evaluation value calculating section 14 for calculating (s) is provided.Diagram
