The present invention is relative to a method for checking tyres, comprising : providing a tyre (3) having a rotation axis (X) on a support plane (2) defining a rested lateral portion (10a) and a freelateral portion (10b) detecting at least one three-dimensional profile of a ring-shaped surface (31) of said tyre with centre in said rotation axis (X), said three-dimensional profile including a height of a plurality of points of said ring-shaped surface; translating a tool (23, 25) towards said tyre arranged on the support plane so as to rest on a measurement surface (M), said measurement surface being a portion of said ring-shaped surface (31); pushing said measurement surface through said tool (23, 25) up to a predetermined tool height calculated with respect to a value that is a functionof a height of said undeformed measurement surface as present in said three-dimensional profile of said ring-shaped surface (31) setting said tyre (3) in relative rotation with respect to said tool (23, 25) so that said tool
