The device is used for facilitating a tire fitting and is usable in combination with a self-centering platform, rotatable about an axis, and with a fitting tool. The device is constituted by an auxiliary tool provided with a frame and having a lower free end which is removably constrainable to the self-centering platform. The frame comprises a support which, when the free end is constrained to the platform, is vertical, lateral and external of the wheel. A pusher element is connected to the support and can move in a parallel direction to a longitudinal axis of the support. The pusher element interacts contactingly with a tire wall situated facing upwards and forces an upper bead to remain below an upper edge of the rim during rotation of the self-centering platform in order to achieve tire fitting.
