Abstract
A pneumatic tire includes: an annular structure that is cylindrical and metal where at least an outer side surface in the radial direction is a rough surface; a tread rubber layer that will become a tread portion provided along a circumferential direction of the annular structure on an outer side of the annular structure; and a carcass portion including fibers covered with rubber, provided on at least both sides in a direction parallel to a center axis of the cylindrical structure including the annular structure and the tread rubber layer.

A pneumatic tire comprising:
- an annular structure that is cylindrical and metal where at least an outer side surface in a radial direction is a rough surface;
- a tread rubber layer that will become a tread portion provided along a circumferential direction of the annular structure on an outer side of the annular structure;
- and
- a carcass portion including fibers covered with rubber provided on at least both sides, in a direction parallel to a center axis, of a cylindrical structure including the annular structure and the tread rubber layer.
A method for manufacturing a pneumatic tire comprising:
- an annular structure that is cylindrical and metal where at least an outer side surface in a radial direction is a rough surface;
- a tread rubber layer that will become a tread portion provided along a circumferential direction of the annular structure on an outer side of the annular structure;
- and
- a carcass portion including fibers covered with rubber, provided on at least both sides, in a direction parallel to a center axis, of a cylindrical structure including the annular structure and the tread rubber layer;
- wherein the method includes:
- a procedure for obtaining the annular structure where at least the outer side surface in the radial direction has been subjected to roughening;
- a procedure for arranging an unvulcanized tread rubber layer on the outer side of the annular structure;
- and
- a procedure for vulcanizing the unvulcanized tread rubber layer and bonding the tread rubber layer and the annular structure.
