A tire dynamic load radius calculating device (1) includes a tire rotation sensor (2s), a drum rotation sensor (3s), a drum rotation angle calculating unit (c1), and a tire dynamic load radius calculating unit (c2). The drum rotation angle calculating unit (c1) is configured to calculate a rotation angle of a drum (3) per one rotation of a tire based on signals from the sensors (2s, 3s). The tire dynamic load radius calculating unit (c2) is configured to calculate a dynamic load radius of the tire (2) based on a formula (R = L/2π), using the rotation angle calculated by the drum rotation angle calculating unit (c1). In this formula, R represents a dynamic load radius of the tire, and L represents a distance traveled by the tire per one rotation of the tire.
