A circumferential main groove detection method for detecting, by a computer, a position of a circumferential main groove of a tire from 3D data of a tread surface of the tire, the method including: a cross-sectional data extracting step of extracting, at a plurality of places in a tire circumferential direction, cross-sectional data of the tread surface along one direction inclined with respect to the tire circumferential direction; an area dividing step of dividing the cross-sectional data respectively into a plurality of areas along one direction; an evaluating step of evaluating relative unevenness in the areas; and a circumferential main groove identifying step of overlaying evaluation results of divided areas at an identical position in the tire circumferential direction and identifying the position of the tire circumferential main groove.
