Abstract: Provided are a tire forming mold which enables damage on ribs and blocks of a tire to be effectively prevented when the tire is removed from the tire forming mold in spite of a simple structure thereof, and a pneumatic tire producing method using the same. The tire forming mold according to the present invention is a two-division type of tire forming mold, including a mold main body for forming one side of the tire, wherein the mold main body is provided with a movable part which constitutes a part of a tread forming surface in the direction of the circumference thereof while the tire forming mold is being closed, and which can be moved while the tire is being removed from the tire forming mold.

Abstract: A pneumatic tire includes a sidewall surface with serrated portions, each of the serrated portions being formed by aligning numerous serrated concavo-convex stripes thereon, the serrated portions being spirally arranged along a circumferential direction of the tire. The concavo-convex stripes are formed by formation of concave grooves on the sidewall surface. The depth of the concave grooves is 0.3 to 2.0 mm. An interval between adjacent serrated portions is set 5 mm or more when measured along a radial direction of the tire.
