PURPOSE:To improve maneuvering stability during turn, by a method wherein a rubber stock having specified hardness is disposed, adjacent to a carcass layer, to the inner side of a carcass layer body where a bead part is not folded back, and the upper end thereof is placed in the vicinity of the maximum width position of a tyre. CONSTITUTION:An inflated tyre has a bead part 3 where the end part of a carcass layer 1 is folded back around a bead wire 2 from the inner side A toward the outer side B of the tyre. In this constitution, a rubber stock 4 having hardness A of 90 or more is disposed adjacent to the body of the carcass layer to the inner side of the body of a carcass layer 1 not folded back at the bead part 3. The rubber stock 4 is positioned adjacent to the inner side of the carcass layer 1 body in a manner to surround a bead filler 5, and the upper end thereof is placed in the vicinity of the maximum width W position of the tyre. This constitution enables improvement of rigidity of a side part during cornering and maneuvering stability.
