Tire forming-mold and tire manufacturing method

In each protrusion-forming recess of a mold, a non-through-hole vent is provided at one end side, and a through-hole vent that is longer than the non-through-hole vent is provided at another end side. When there is an ingress of rubber of a green tire into each protrusion-forming recess, air inside the protrusion-forming recess is discharged through the through-hole vent and the minute amount of air remaining inside escapes to the non-through-hole vent. Each through-hole vent is set with a large capacity, enabling an ingress of rubber into the vent hole that will later become spew to be stopped inside the through-hole vent. Since the volume of air that is trapped inside the protrusion-forming recess is a minute amount, and so the volume of air that escapes into the non-through-hole vent is also a minute amount.
