An apparatus for checking a tyre, having a support, a deformation system, a lighting arrangement, a moving member and a processing unit. The deformation system is configured to form an elastically deformed portion of inner surface and an elastically deformed portion of outer surface on the tyre. The lighting arrangement includes light sources and cameras to illuminate and detect deformed inner and outer surface portions of the tyre, and generate corresponding control signals. The moving member sets the support in relative rotation with respect to the light sources and the deformation system around a rotation axis of the tyre. The processing unit is configured so that while the light sources illuminate the deformed portions of outer and inner surfaces, the deformation system acts and the moving member imparts the relative rotation.
