Method for checking tyres, each tyre having a main rotation axis (X-X) and an axial centreline plane, said method comprising: simultaneously advancing tyres step by step along a check path and checking said tyres during time intervals placed between subsequent steps; wherein for each of the tyres, provision is made for: ■ checking at least one first half of the tyre by executing a plurality of checks along a first part of the check path, wherein the first half is an axial half of the tyre delimited by said axial centreline plane; ■ overturning said tyre around an overturning axis after the exit from said first part of the check path; ■ conducting said tyre to the inlet of a second part of the check path; ■ checking at least one second half of said tyre by executing the same plurality of checks along said second part of the check path, wherein the second half is the other axial half of the tyre delimited by said axial centreline plane; characterised in that during each of said time intervals, the tyres are subjected to a plurality of successive check cycles; wherein during each of said check cycles, check tools (43a,43b,43c,43d,43e,43f,43g,43h) are arranged in fixed check positions while the respective tyres rotate around respective main axes (X-X); wherein between one check cycle and the next, check tools (43a,43b,43c,43d,43e,43f,43g,43h) are moved into different check positions. simultaneously advancing tyres step by step along a check path and checking said tyres during time intervals placed between subsequent steps; wherein for each of the tyres, provision is made for: ■ checking at least one first half of the tyre by executing a plurality of checks along a first part of the check path, wherein the first half is an axial half of the tyre delimited by said axial centreline plane; ■ overturning said tyre around an overturning axis after the exit from said first part of the check path; ■ conducting said tyre to the inlet of a second part of the check path; ■ checking at least one second half of said tyre by executing the same plurality of checks along said second part of the check path, wherein the second half is the other axial half of the tyre delimited by said axial centreline plane; characterised in that during each of said time intervals, the tyres are subjected to a plurality of successive check cycles; wherein during each of said check cycles, check tools (43a,43b,43c,43d,43e,43f,43g,43h) are arranged in fixed check positions while the respective tyres rotate around respective main axes (X-X); wherein between one check cycle and the next, check tools (43a,43b,43c,43d,43e,43f,43g,43h) are moved into different check positions. ■ checking at least one first half of the tyre by executing a plurality of checks along a first part of the check path, wherein the first half is an axial half of the tyre delimited by said axial centreline plane; ■ overturning said tyre around an overturning axis after the exit from said first part of the check path; ■ conducting said tyre to the inlet of a second part of the check path; ■ checking at least one second half of said tyre by executing the same plurality of checks along said second part of the check path, wherein the second half is the other axial half of the tyre delimited by said axial centreline plane;
