Claim 11:
12. A method for checking tyres, comprising:
arranging a tyre in a station for checking tyres;
moving at least one sensor within the tyre;
performing first checks on an inner surface of the tyre with the at least one sensor;
engaging a radially outer portion of the tyre with grip elements of an overturning device;
extracting the at least one sensor from the tyre and spacing the at least one sensor from the tyre;
overturning the tyre by 180° by rotation of the grip elements around an overturning axis perpendicular to a rotation axis of the tyre;
moving again the at least one sensor within the tyre;
performing second checks on the inner surface of the tyre with the at least one sensor;
extracting again the at least one sensor from the tyre and spacing the at least one sensor from the tyre;
transporting the tyre outside the station for checking tyres;
after the arranging and before the moving, engaging a bead of the tyre with a grip member to lock the tyre on the grip member;
after the engaging and before the overturning, disengaging the grip member from the tyre while the tyre is retained by the grip elements;
after the overturning and before the moving again, engaging an opposite bead of the tyre with the grip member;
disengaging the grip elements from the radially outer portion of the tyre; and
after having locked the tyre on the grip member and prior to performing the first checks on the inner surface of the tyre:
lifting the tyre from an abutment plane,

wherein moving said at least one sensor within the tyre comprises:
lowering a mechanical arm, said at least one sensor being placed at one end of the mechanical arm.
