The present invention provides a tire casing including a sidewall part, a bead part, a carcass ply, and a belt part and having been previously vulcanized prior to sticking a tread member, wherein when a distance from an end part of the tread member joint surface to an end part of the bottom surface of the bead part along the surface of the sidewall part is defined to be 1, the tire casing has a side rubber member (A) extending in a proportion of from 0.09 to 0.30 of the distance along the surface of the sidewall part from the end part of the tread joint surface, and the side rubber member (A) contains 100 parts by mass of a rubber component comprising at least one or more selected from the group consisting of a natural rubber, a synthetic isoprene rubber, a polybutadiene rubber, and a styrene-butadiene copolymer rubber, and from 40 to 100 parts by mass of carbon black having a nitrogen adsorption specific surface area (N 2 SA, as measured according to JIS K6217-2:2001) of from 70 to 150 m 2 /g. Thus, a tire casing capable of not only enhancing low fuel consumption but also enhancing external damage resistance of a shoulder portion of a sidewall part close to a road surface is provided.
