Claim:
1. A method for controlling tyres in a tyre production line, comprising: predisposing a tyre to be controlled, the tyre having a rotation axis and a middle line plane orthogonal to the rotation axis; elastically deforming a portion of a lateral wall of said tyre by imparting, through physical contact, a force of compression on an outer contact surface belonging to said lateral wall portion, said compression force having at least one component parallel to the rotation axis and sense directed toward the middle line plane; illuminating, with a light radiation, one surface of said lateral wall portion and detecting an image of said illuminated surface; generating at least one control signal representative of the detected image; and analysing said at least one control signal in order to detect a possible presence of flaws on the lateral wall portion.
