Abstract: A method and an apparatus for forming a carved groove of a green tire capable of forming a carved groove of a necessary depth without being influenced by variation of outer diameters of the green tire is provided. In a method and an apparatus for forming a carved groove for a lug groove with a cutter on an outer circumferential surface of a green tire before curing, a distance sensor is moved along a portion to be carved on the outer circumferential surface of the green tire to measure outer diameters of the portion to be carved, cut shape data for a green tire having an ideal shape stored in memory beforehand is revised on the basis of the measured outer diameters, and the cutter is moved in accordance with the revised cut shape data for carving.
