To provide a tire wear degree estimation device that is able to expect a further improvement in estimation accuracy in estimating a vehicle tire wear degree per travel distance.SOLUTION: A tire wear degree estimation device for a vehicle includes: dynamic load radius information acquisition means that acquires dynamic load radius information on a tire of the vehicle; load information acquisition means that acquires load information on the vehicle; tire air pressure information acquisition means that acquires tire air pressure information on the vehicle; travel distance information acquisition means that acquires travel distance information on the vehicle; and tire wear degree estimation means that estimates a tire wear degree per travel distance of the vehicle. The tire wear degree estimation means estimates a tire wear degree per travel distance by using the dynamic load radius information and the travel distance information at a time point at which both the load information acquired by the load information acquisition means and the tire air pressure information acquired by the tire air pressing information acquisition means can be regarded as the same.SELECTED DRAWING: Figure 1
