Zusammenfassung:Method for checking tyres, and relative station (100), comprising: - illuminating a first portion of outer surface by means of a first illumination system (6) with a first light source (11) turned on and a second light source (12) and third light source (13) in respective inactive positions more backward along said first optical axis (8) with respect to the first light source (11), and acquiring a first two-dimensional image by means of a camera exerting a compression force in order to elastically deform the first portion of surface; - illuminating a second portion of outer surface by means of the first light source (11), second light source (12) and third light source (13) in time sequence, with the second light source (12) and the third light source in the respective active position more advanced along the first optical axis (8), and more distal from the first optical axis, with respect to the first light source (11), and acquiring respective second two-dimensional images of the second portion of surface by means of the camera; - illuminating a third portion of outer surface by means of a second illumination system (7) almost telecentric with a second optical axis (9) which forms an angle with the first optical axis greater than or equal to 60° and less than or equal to 100°, with the first illumination system (6) turned off, and acquiring a third two-dimensional image of the third portion of outer surface by means of the camera (5).
