The invention aims at providing a tire with a specially shaped tire bead, which is energy-saving and light in weight and is capable of fully playing the overall performance of a bead ring. The tire comprises sidewall rubber, edge margin outer protective rubber, carcass ply, a transition layer, an air-tight layer, a rubber core and an edge margin part, wherein the sidewall rubber is arranged on the outer side of the tire, and extends downwards to the edge margin outer protective rubber; the edge margin part is arranged on the lower side of the edge margin outer protective rubber; the carcass ply is arranged on the inner side of the sidewall rubber; the transition layer and the air-tight layer are arranged on the inner side of the carcass ply from outside to inside; the carcass ply downwards extends to the edge margin part and is of a dual-layer integrated structure; the rubber core is arranged on the upper part of the inner side between the double layers of the carcass ply; the specially shaped bead ring is arranged at the lower part of the inner side between the double layers of the carcass ply; the carcass ply wraps the lower part of the specially shaped bead ring; the upper part of the specially shaped bead ring is filled with the rubber core; a reinforcing film is arranged on the outer side of the part, in the edge margin part, of the carcass ply; two bending sections are arranged on the connected part of the outer side of the edge margin part and a rim; the bending section I sinks inwards; the bending section II protrudes outwards. According to the tire with the specially shaped tire bead, the weight of the tire is reduced, the rolling resistance is reduced, and thus energy saving and consumption reducing are facilitated.
