PURPOSE: An apparatus for measuring the sole width of tread of a tire is provided to reduce failure rate due to the extrusion process of the tread by reduction in the error range of the width of the tread measured. CONSTITUTION: An apparatus for measuring the sole width of tread of a tire comprises first and second lighting devices(16a,16b), a servo motor(25), a driving controller(30), and an image processing module(40). The first and second lighting devices are placed on both sides of a tread(14) transferred by a conveyer belt(12). The first and second lighting devices lights the side of the tread. The sub-motor is placed in the upper space of the conveyer belt vertically to the transfer direction of the tread. The driving controller controls the operation of the first and second cameras(20a,20b). The image processing module receives and processes image signals from the first and second cameras.
