Tire mounting method using a tire mounting device

A tire mounting method for automatically mounting a tire onto hub bolts of a motor vehicle, comprising the steps of:

• gripping the tire and temporarily tightening nuts on the hub bolts on which the tire has been placed with a first working mechanism;
• after the tire is set to a first mounting region by the first working mechanism, fully tightening the nuts that have been temporarily tightened by the first working mechanism with a second working mechanism, which is disposed in association with the first mounting region on a front wheel side of the motor vehicle, and has a base arm and an arm separate and distinct from the first working mechanism;
• and
• after the tire is set to a second mounting region by the first working mechanism, fully tightening the nuts that have been temporarily tightened by the first working mechanism with a third working mechanism, which is disposed in association with the second mounting region on the rear wheel side of the motor vehicle, and has a base arm and an arm separate and distinct from the first working mechanism and the second working mechanism,
• wherein all of the first working mechanism, the second working mechanism, and the third working mechanism are positioned on a same side of the motor vehicle when viewed along a direction in which the motor vehicle is conveyed, and the first working mechanism is disposed between the second working mechanism and the third working mechanism.
