1. 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; and
after the arranging and before the moving, performing a preliminary centring of the tyre along a transverse direction by symmetrically and simultaneously moving a first grip element and a second grip element of the overturning device up to bringing the first grip element and the second grip element against diametrically opposite zones of the radially outer portion of the tyre while the tyre abuts against an abutment plane and
subsequently spacing the first grip element and the second grip element from the tyre.
