To provide a control apparatus capable of properly performing tire rotation.SOLUTION: A control apparatus comprises an input part into which information on how to use a plurality of tires attached to a vehicle is input, and a calculation part that calculates a residual travel distance until differences among groove depths among the plurality of tires exceed a predetermined allowance, on the basis of the information on how to use the tires. For example, the information on how to use the tires includes at least one of tire air pressure, the number of times of steering, a steering speed, an axle load, a vehicle speed, vehicle acceleration, vehicle deceleration, an engine torque output value and lateral acceleration of the vehicle.SELECTED DRAWING: Figure 1 【課題】タイヤローテーションを適切に行うことができる制御装置を提供すること。【解決手段】制御装置は、車両に装着された複数のタイヤの使われ方に関する情報が入力される入力部と、タイヤの使われ方に関する情報に基づいて、複数のタイヤ間における溝深さの差が予め定められた許容値を超えるまでの残走行距離を算出する算出部と、を備える。例えば、タイヤの使われ方に関する情報は、タイヤのエア圧、ステアリング操舵回数、ステアリング操舵速度、軸重、車両速度、車両加速度、車両減速度、エンジントルク出力値および車両の横Ｇの少なくとも１つを含む。【選択図】図１
