Change in a regression formula for correcting a rotation speed is found early. A correction device includes a rotation speed acquisition unit, a comparison value calculation unit, a torque acquisition unit, a regression formula specification unit, a rotation speed correction unit, and a verification unit. The rotation speed acquisition unit acquires a rotation speed of each of a first tire and a second tire mounted to a vehicle. The comparison value calculation unit calculates a comparison value showing comparison between the rotation speed of the first tire and the rotation speed of the second tire. The torque acquisition unit acquires a wheel torque. The regression formula specification unit calculates, based on the comparison value and the wheel torque, a parameter that specifies a regression formula in which the comparison value is modeled, the regression formula including an element dependent on the wheel torque. The rotation speed correction unit calculates, based on the rotation speed of the second tire and the parameter, the rotation speed of the first tire in which influence of slipping is canceled. The verification unit compares an estimated comparison value estimated based on the wheel torque and the parameter calculated by the regression formula specification unit, with the comparison value calculated by the comparison value calculation unit. One of the first tire and the second tire is a front wheel tire, and another of the first tire and the second tire is a rear wheel tire. The first tire is a tire to which a driving force larger than that to the second tire is applied.
