　ところで、近年、複数のユーザで車両を共用するカーシェアリングが普及しているが、次のような問題が顕在化している。具体的には、カーシェアリング用の車両は、異なる保管場所（駐車場）に点在しており、カーシェアリングの事業者または車両のメンテナンス事業者が日常的に当該車両を点検することは容易でない。 Incidentally, in recent years, car sharing in which a vehicle is shared by a plurality of users has become widespread, but the following problems have become apparent. Specifically, vehicles for car sharing are scattered in different storage locations (parking lots), and it is not easy for car sharing operators or vehicle maintenance operators to check the vehicles on a daily basis. .
　特に、車両自体と比較して日常的な点検の必要性が高い内圧及び摩耗状態など、当該車両に装着されたタイヤの状態を点検することは容易ではない。ユーザにタイヤの点検を委ねることも考えられるが、完全性を期すことは難しい。また、点検のために当該車両の保管場所に保守者が出向くことは、コストが掛かる。 Especially, it is not easy to check the condition of the tires mounted on the vehicle, such as the internal pressure and the worn state, which are more frequently required for daily inspection than the vehicle itself. Although it is conceivable to leave the tires to the user, it is difficult to ensure completeness. In addition, it is costly for a maintenance person to go to the storage location of the vehicle for inspection.
