Tire, tire mold, and tire production method

A tire comprising:

• a bead portion configured to fit onto a rim, wherein
• the bead portion includes a first vent line extending in a circumferential direction, a second vent line outward of the first vent line and extending in the circumferential direction, a columnar protrusion outward of the second vent line, and a saw cut extending between the first vent line and the columnar protrusion and intersecting the second vent line,
• the first vent line, the second vent line, the columnar protrusion, and the saw cut project from an outer surface of the bead portion,
• the second vent line is on the columnar protrusion side with respect to a midpoint between the first vent line and the columnar protrusion,
• the saw cut has a width smaller than an outer diameter of the columnar protrusion,
• a ratio of a distance from the first vent line to the second vent line to a distance from the first vent line to the columnar protrusion is not greater than 70%,
• the bead portion includes a bead including a core extending in the circumferential direction and an apex radially outward of the core,
• the outer surface of the bead portion includes a seat surface radially inward of the bead, a flange surface axially outward of the bead, and a heel surface between the seat surface and the flange surface,
• in a cross-section of the tire along a plane including a rotation axis of the tire, a contour of the heel surface is represented by an arc, and
• the first vent line is at a center portion of the heel surface.
