Abrégé

The invention relates to a device for testing a tyre (2) for representing tomographical images of sections of casing of said tyre, comprising a source (11) of ionizing radiation arranged outside said tyre (2) and a detector (12) for receiving said radiation, said detector (12) being situated opposite said source (11) with respect to at least one section of casing, the axis (X-X) of said tyre running parallel to a sectional plane (P) passing through the focus (F) of said source (11) and said detector (12), whereas said tyre and the source-detector assembly are moved with a rotational motion relative to one another about an axis of rotation (Z-Z) perpendicular to said sectional plane (P), according to a predetermined angular excursion range. According to the invention, said detector (12) is designed to be disposed in a central internal zone (20) of said tyre (2) during the implementation of a testing cycle.
