Provided is a tire post-inflation device. The tire post-inflation device includes a framework, a lifting rod, a chuck assembly, lifting drive cylinders, and a pressing assembly. The lifting rod is disposed on the framework. The chuck assembly is connected to the lower end of the lifting rod. The chuck assembly is formed with an inflation port for inflating a tire. The lifting drive cylinders are disposed on two sides of the lifting rod. The lifting drive cylinders are configured to drive the lifting rod to move up and down. The pressing assembly is disposed on the framework. The pressing assembly includes a pressing rod and a drive assembly. The drive assembly is configured to drive the pressing rod to press the lifting rod that is lowered into place.

A device for cooling and stabilizing a cured tyre, includes a beam with a non-movable element; a movable element; a guide; and an actuator arranged to move the movable element along the guide relative to the beam. One of the non-movable element and the movable element includes a shaft having at its end a spline, and a first disc in the axis of which the shaft is arranged. The other of the non-movable element and the movable element includes a closing mechanism including a second disc with a threaded axial opening, a main electric motor and a securing socket having a cylindrical shape with a thread. The closing mechanism is configured to cooperate with the shaft via the securing socket corresponding to the shape of the spline and to adjust the size of the tyre through sliding, along the axis, of the second disc.
