A method for inspecting three-dimensional forms of one or more marks formed with unevenness on a surface of a tire, which comprises a step of measuring heights of unevenness inclusive of these marks on each area element in a predetermined tire surface region to acquire data of unevenness distribution, a step of specifying a tire surface portion corresponding to a mark model for the respective mark in the tire surface region from data of three-dimensional form of a previously prepared mark model as a mark template and the acquired data of the unevenness distribution, a step of determining a coincidence between the data of the unevenness distribution and the data of the three-dimensional form of the mark model in the specified tire surface portion on the respective mark to judge an acceptance of the three-dimensional form of the respective mark based on the coincidence.
