An apparatus for checking tires described as a linear camera having an objective line lying on an optical plane; a first, a second and a third light source for emitting respectively a first, a second and a third light radiation; a command and control unit for selectively activating at least one from among the first, second and third light source and activating the linear camera in order to acquire a two-dimensional image of a linear surface portion of the tire synchronously with the activation of the first, second and third source. The first and second light source lie on opposite sides of the optical plane. Furthermore, the first, second and third light source include each one or more sub-sources each having a respective main extension direction parallel to the optical plane and the distance of the sub-sources of the third light source from the optical plane is less than the distance of the first and second light source from the optical plane.
