Patent abstract
Provided is a mold for vulcanization of a tire which does not entail troublesome work including removing vent spews, and which does not spoil the external appearance of the tire with the spews, and prevents light failures from occurring in the tire. Vent grooves are formed in sidewall molding surfaces for molding sidewall parts in such a way as to extend zigzag in the tire circumferential direction. At least one vent hole is formed in each of the vent grooves.
