PURPOSE:To aim at saving the labor for replacement of large size aircraft tires by supporting a tire holding means to the rear of the deck of a vehicle body through a swingable and turnable link mechanism, and by providing support columns which can be operated by an actuator and a link mechanism. CONSTITUTION:A support arm 9 in a tire holding means 7 is attached to a support column 5 planted on the rear end of a vehicle body deck 2 projected from the rear end part of a self-propelling type vehicle, through a swingable parallel link mechanism 4. The tire holding means 17 is composed of a tire holding frame 18, a holding roller 20 and a height adjusting mechanism 21. Support column arms 30 which can be swung by an actuator 39 and upper and lower links 36, 34 are provided on both sides of the vehicle body deck 2, and a stamp body 32 is provided at the front end of the vehicle body deck 2. A large size aircraft tire W is supported by the holding means 17 while a support column 26 is grounded in a stable condition, thereby it is possible to facilitate the replacement of tires with no human labor.
