A vehicle stability control device is mounted on a vehicle in which a front tire wears faster than a rear tire. An equation for calculating a target yaw rate includes a stability factor of the vehicle as a parameter, wherein the calculated target yaw rate becomes lower as the stability factor becomes larger. Understeer degree increases as the target yaw rate becomes higher than an actual yaw rate. When the understeer degree exceeds an activation threshold, vehicle stability control is activated. The vehicle stability control device further performs wear coping processing. In the wear coping processing, a wear degree parameter being wear degree of the front tire or a difference in wear degree between the front tire and the rear tire is calculated. When the wear degree parameter exceeds a wear threshold, the vehicle stability control device corrects the stability factor to be larger than a default setting value.
