The provided is a tire manufacturing method for obtaining a tire 10 that comprises a tire body part 11 and a tread rubber part 12, comprising: a base tire preparation process S101 preparing a base tire 1, which is a tire body part of a used tire and will become the tire body part 11; a molded tire assembly process S102 assembling a molded tire 4 by attaching tread rubber 2, which will become the tread rubber part 12, to outer circumference side of the base tire 1 prepared; a molded tire vulcanization process S103 vulcanizing the molded tire 4 assembled; and a sipe formation process S104 forming a sipe 16 on a surface 5 of a tread of the molded tire 4 vulcanized.

A sipe forming system is provided. The sipe forming system includes a cutting base including a pivot plate having an aperture, a cutting drum extending at least partially through the aperture, a blade coupled to the surface of the cutting drum, and a mechanical power source operably coupled to the cutting base and configured to rotate the cutting drum. The sipe forming system further includes a positioning assembly pivotally coupled to the cutting base and configured to receive a tire tread. The positioning assembly includes a housing, the housing being selectively positionable relative to the pivot plate, and at least one positioning device configured to position the tire tread received by the positioning assembly with respect to the cutting drum.
